Delayed post #1: aspects of [web] preservation

[[this post never got finished but I'm having a clear-out of my drafts and they're getting published or deleted, ready or not]]

Brian Kelly just blogged [[hmm, well, back in July, I think....]] on the JISC-PoWR site about "three key aspects of web preservation": experience, information, and access. I have a fourth, but I've been using it in the context of "sustainability" (the subject of my thesis), and so first I want to say a couple of words about this vs preservation, since although I've been writing papers for Ross for a couple of years arguing about the distinction between the concepts, I've not really rehearsed this in public before.


For the last couple of years I've been arguing that the problem of sustainability (S) is distinct from that of archive-style preservation (P). I won't go into the details of the distinction here but in essence I see P as concerning the persistence of a state, and S as the persistence of a process or activity. Recent work by Chris Rusbridge and others has been blurring the boundary ever more, although in a useful way: by questioning the purpose of preservation and weighing up what are the important aspects ("significant properties") of resources, they have been starting to argue for an approach to preservation that looks a lot more like what I was previously describing as sustaining. I still sort of believe that it is useful to distinnguish between the two concepts, but there's a lot of overlap.


The aspect that I think is especially pertinent to sustaining is "purpose". I don't think this is the same as the "experience" that Brian cites Kevin Ashley on (although experience and information may feed into purpose). It's focused on the objectives of the resource, which may be attainable through radically different experiences; for example (in the case of the environment in which KA operates), the learning objectives that an educational resource was created to serve. For a museum, perhaps a resource was prepared for use in a temporary exhibition, with the objective of enriching the experience visitors to that physical space by illustrating relationships betweeen objects, and providing media resources to bring them to life. When that exhibition closes, the original objective is partially voided - there is no physical visit to enrich - but aspects of it may still be viable - the objects probably still exist and the tales about them are still worth telling, perhaps more so than ever since we've stuck them back in the store-room out of easy access. Brian was talking about web preservation, of course, and I've taken a non-web resource as an example, but my interest in the question of sustainability extends beyond the web and the point applies regardless.

In any given digital resource that we're talking about preserving/sustaining, experience and information at least (perhaps access, too, sometimes) will have contributed to the original purpose to varying degrees - sometimes the experience is the whole purpose, sometimes it's an unimportant side effect of providing access to information. And sometimes it's important to the preserver regardless of its significance to the original purpose.

So if the original purpose is no longer served by a resource, what then for our "preservation" plans? There are still often reasons to preserve (freeze) or sustain (keep alive) an application, or aspects of it - in other words, some sources of value, ranging from historical interest to new uses, which may let a resource adapt and survive. The "significant properties" idea fits in to this. For me, if you are trying to maintain some quality of the original it's more of a preservation activity; whereas if you are more fundamentally interested in continuing to extract value through maintaining utility of whatever sort, we're talking sustaining.

EDLocal >> EuropeanaLocal

Fleur says: EDLocal becomes EuropeanaLocal. I'm looking forward to hearing what else came out of the recent launch of the project, which will hopefully help to smooth the process of participating in Europeana for institutions of all sizes. I'll keep you posted (but I expect Fleur will do a better job so keep an eye on her blog!)

Two interesting ReadWriteWeb stories

Just a quickie. Two things caught my eye on RWW:
Confirmed: Microsoft Acquires Powerset. So MS moves into semantic search with the acquisition of a promising startup. Yahoo! will have to fight ever harder for survival if MS is really determined to do this. Anyway, it may be time to start talking to MS about how to work with all the yummy structured data we have in MLAs (yes, that means you EDL)
Gnip: Grand Central Station for the Social Web. This is all about tackling the myriad interfaces and data formats of social software APIs. It's a comparable problem to that faced in our sector and the solution of a mediator is interesting mainly for that reason. It's also potentially directly relevant where we're working with data in social sites.

Showing us the way

I presume it's uncontroversial to say that it would be useful to have terminologies available as web services. Right now, you can browse various sources of reference terms that are useful to museums (amongst others): sources like the british & irish archaeological bibliography (including its approved term lists); the National Monument Record Thesauri; and the museum codes and SPECTRUM terminology termbank maintained by the Collections Trust (to highlight some UK examples). I'm certain it would be useful to have these available as web services (some more so than others); likewise other thesauri that AFAIK aren't available to programme to: ULAN and AAT, for example, which are collected under the CCO initiative.

There's every chance that I misunderstand some or all of these "services" in terms of how they're used and by whom (I'm very shaky on the status of CCO and its relationship to AAT, for a start). But I'm sure that there are many ways in which a programmatic interface to their contents could be used. Which is why (to get to the point of this post) the service that OCLC's top geeks have come up with here is a great example for us in the museum world to look at (blogged here on Hanging Together). This is a collection of esssentially library-related thesauri onto which they have created web services. I like the look of FAST best of all; it could be really useful for us in the dusty bones world too.

Lorcan Dempsey also blogs today about the WorldCat identities API and other cool services. I fancy the name look-up service: aside from anything else it gives us a URL to refer to for those individuals in the WorldCat database. Here's a not-so-random entry.


So once again we can learn a lot from libraries leading the way. One of the cool things, though, is that OCLC are a cross-domain organisation, and people like Dempsey think constantly about breaking down the barriers between libraries, archives and museums. If they've sprinkled their magic onto library terminologies, I'm sure they'll be only too happy to help the museum world to take similar steps.

Mike Dunn on "technical due dilligence"

Extracted from an interview with Mike Dunn of Hearst, published on ReadWrite Web, these are the top five aspects of "technical due dilligence" that Dunn looks for when considering a startup for acquisition.


  1. The primary things I look for are a thorough understanding of a company's current technology state and a roadmap of their future. I then fill in the building blocks to paint a picture of the company and its structure via the next 4 areas.
  2. Staffing: The company should have a proper ratio of dedicated to outsourced staff. The focus for in-house staff should be on owning and extending the company's value-add. The focus of the outsourced staff / service should be on areas where technology is available at a reasonable price.
  3. Infrastructure and Architectural: I look for alignment between the infrastructure in place and their roadmap. I try to understand their architecture, i.e., have they designed something that will be stable, yet scale and grow as their business requires? Have they over or under built, are their investments proper for current state and extensible as their growth requires?
  4. Workflow and Processes: This is usually the hardest part of my interviews with startups because while most have ways they do things, they often aren't comfortable expressing them. They also aren't normally done in a way that's repeatable to the point where they could be called a workflow. This is OK. As they mature, standardized workflows and processes will be established, normally out of a necessity to ensure they're providing a stable environment that doesn't get negatively affected as they introduce change.
  5. Costs: This is the spreadsheet part of the conversations. What has been spent to get them to the point they're at, what do they need to spend near term, possibly with funding from my company, and what do they envision they'll need to spend? I look for a grounded approach to spending.


With a little flipping around these consideration probably apply just as well to museums.

Conference ketchup

Well it's been a pretty busy time. After many years of avoiding presenting at conferences, following a number of crappy performances in '99, I bit the bullets kindly shot at me by Ross and Jill and opened my cakehole to several hundred unfortunate captives, first at the UK Museums on the Web conference in Leicester, and then at the EDL plenary conference in the Hague. And I'm truly grateful to both Ross and Jill for the opportunity to do this: it's very flattering, humbling, really, that they felt I'd have something worth saying to such informed and inquisitive audiences.

In the end, nervous anticipation gave way to the onrush of time and once I was up there in front of faces familiar and not I felt a more at ease than I would have expected. Having listened to the recordings, well, there were a lot more "ums" and "errs" than ideal, but hey, I didn't forget too many things and I kept pretty close to time, which is a big improvement on my earlier debacles.

So what was I talking about? In Leicester, I talked about Europeana. It was not meant to be an overview as such (that's not really my role), but an account of my involvement and interest, focussing on my hopes for the project and, of course, the role that APIs play in that. During Q&As and coffee breaks I had a lot of really useful feedback to my question: what is stopping many more UK museums from getting involved in the project? On the whole these revolved around the burden and mechanics of providing data, which was pretty much as I suspected. It's made me more determined to do what I can to simplify these processes, but also to ensure that the pay-off to partners is as high as it can be and as well understood as possible. Perhaps we have the furthest to go to achieve the latter.

At the Koninklijke Bibliotheek in the Hague I had an even shorter slot, which was fine by me, as part of a panel whose other members were intimidatingly illustrious. The subject of the conference was "Users expect the interoperable", and this particular session had two panels discussing interoperability in relation to archives and museums, respectively. I took part in the latter panel. I still don't know if I actually said anything, really, because I had little in the way of conclusions to offer: I just teased out some ways in which I thought "interoperability" questions pertained to APIs in a museum context. I also looked at a few examples from the world of semantic enrichment - a strange choice, perhaps, but made because there are really no proper museum APIs to compare to, and in order to show that a lack of standardisation in that area is no barrier to those APIs (Calais, Hakia, and Yahoo! Term Extractor) being useful. Simplicity gets you a long way, as does the use of existing data formats (e.g. DC or microformats). These also fit well with the other drum I was banging, the services that EDL could offer to contributors and third parties for enriching content. So, a kind of bitty talk but at least it was brief!

On Tuesday the conference wrapped up (and I do want to talk a lot more about it ASAP, because apart from anything else the first prototype was shown off and it's COOL!). I attended a hurried meeting of WP1 and Harry Verweyen presented his paper on the business model. I think he's done a great job, although this is so far outside my area of comptence I scarcely dare comment. He'd also done a lot of work integrating some of my suggestions into the plan, and it became still clearer to me how much of this hangs off the success of the semantic web tech part of the project.

Both conferences were really rewarding in their own ways and I'll try to offer some proper notes from them as soon as I find my feet again.

Hakia, semantic enrichment, and EDL

Moving in the same direction as Reuters, with its OpenCalais service, Hakia has started offering two new APIs, one related to search and the other to content summarising and enhancement (see RWW's story). Perhaps it has some way to go before this is a really useful service in terms of the quality of its output (if RWW's experience is any guide) but it's early days. In any case, putting this alongside Calais and Yahoo!'s Term Extractor (not to mention other semantic enhancement services extracting, for example, location data), this shows at least that there are quite a few people out there that think there's a market for this sort of service.

Semantic enhancement (as well as data validation) is a service that I've mooted as a possibility for Europeana. With a specialist and very authoritative data set, it could appeal to those needing to enrich cultural heritage content. There may not be a lot of money in it, but as Harry Verwayen pointed out to me, that's not necessarily the only benefit to the service provider (or I doubt Reuters would be in this game). Building traffic around the site and strengthening the brand is a benefit. Similarly, increasing the use of the ontology/thesauri used by EDL increases its influence.

Harry is putting together a presentation for next week's WG1 meeting after the EDL plenary, and he's generously put my name on the front too although I have little to contribute beyond these slightly flaky suggestions. We'll be throwing these ideas into the mix in a discussion of business models for EDL when it goes live.

Clarification

Following my off-the-cuff post about the Museum of London's strike (in which I did not participate, not being a member of a union), it's become apparent that there is some confusion as to the status of this blog. It's important, therefore, that I make it very clear that the contents of The Doofer Call are a personal expression only. This is a research diary for my PhD that I've chosen to make public in order to engage in debate and help people find things that interest me; my profile states this. However, because I talk regularly about things I'm doing at the Museum I can see that casual readers might mistakenly believe that I am writing in an official capacity, or with official sanction, and any confusion is my fault and for me to address. Hence this post.

Friday's missive may turn out to be factually incorrect (one might argue that the pay at MoL is not rubbish, or that the pay rise was not over a year late) or inaccurate in its representation of the reasons for the disgruntlement that led to the unions striking, but that's not really the point. What's important is that it's clear that what I wrote was not an official press release, but the completely unofficial, independent expression of someone who is also employee, written at home, out of office hours (like this).

So for clarity, I am posting a disclaimer that can also be read as a declaration of interests. Please read it here.

My apologies to anyone who previously mistook this blog to be anything other than my thoughts in my words, I hope this has made things clearer.

Note: all of the organisations with which I have a formal relationship are included as tags on this post in the hope that people searching for the organisations and stumbling across this blog will also see this clarification.

Disclaimer and declaration of interests

The following are organisations with which I have a formal relationship (most of which I've written about at some point). The opinions expressed on this blog are mine alone, and are not to be attributed on the basis of this blog to any of these organisations:
  1. Museum Of London, my employer. This includes Museum in Docklands and MoLAS. The Museum is also a contracted partner in my PhD

  2. the City of London Corporation write the contracts and the pay cheques, and the Greater London Authority are 50% partners in the Museum

  3. University of Leicester, Department of Museum Studies, at which I am studying for a PhD

  4. Lexara (and previously Simulacra and MWR), the non-academic partner in my PhD. Lexara also supply some technology to the Museum of London.

  5. Richard de Clare Primary School, where I am a parent governor with oversight over ICT across the curriculum

  6. EDLNet, the EC project for which I am the official representative of the Museum of London

None of the above sanctions or previews anything that I write here. Equally, you should read my remarks in the light of my committments to them all.

If anything written here is inaccurate or unclear, please contact me directly or through comments about changing it.

Victorian photographers API now also alphatastic

Didn't manage (didn't dare) to upload this before going-home time on Friday. There is now another string to the bow of the nascent REST alpharama here. You can query the people in the database of 19th Century photographic London (pardon the contraction) at the PhotoLondon website we launched recently. Right now, it only sends you back a list of people matching your criteria (100 records per page) with no details. I will soon produce a detailed machine-friendly record page for each person (an example of a human-friendly one is here)

The querystring takes most of parameters you can see on the form including surname, forename, search text (but not multiple words like the form), gender, year of birth/death, "alive in..." year, place of origin, photographic occupation, non-photographic occupation, and presence of attached images. Here's an example search so you can see what you'll get back right now. Here's a wider one.

There are bugs, no doubt, and it will be of more use when I can send you the person's details, as well as a list of countries and occupations to build queries from. I realise I also need to write some proper documentation. Still, it's a start. Please tell me if it might be useful to you, and what you'd like to see it doing/do with it.

Guardian bigs up the 24 Hour Museum

Jack Schofield today writes up 24HM here. It's funny timing - as he himself points out, it's looking at a relaunch pretty soon - but perhaps there are clues in that as to the timing of this review. It's a pretty positive piece on the whole but suggests that "Culture 24 could be so much better" (after its relaunch). I'm as intrigued as JS to know what's planned - and whether, for example, it will be able to consume/aggregate RSS feeds as well as publish them!

Small API update

A couple of small advances on the API front (again, see here)


  • fixed a bug on the geo thing. For some reason an imbecilic code error wasn't breaking the script on my machine, but did on the web server. Now fixed.

  • a CDWALite-lite output for individual object records (example). There's more to add, glitches to fix, and ideally a better solution to the URL, but it's a start. Next thing is a search interface but that depends upon agreement within the Museum. A good solution may be to combine CDWALite and OpenSearch-style RSS, with the records enabling users to find the data end-point, as well as the HTML rendering. In due course I'll probably add tags to HTML record pages to point at data like this, or I may do it with some POSH.

  • the photoLondon website data now has a basic API, which I'll put on the live site next week. It returns basic person details and search parameters include: surname, forename, keyword, birth year, death year, "alive in" year, gender, country of origin, photographic occupation and non-photographic occupation. I'll work on the search result format soon, as well as the person details.

MoL APIs live (but very alpha)

Well there's more to do, but an alpha version of three services is now there if you want to play. All of them currently put out only XML, no JSON or raw text, GEDCOM or whatever else, but this may change and new services may be added. Have a read here. There is an events database, publications from our Archaeology Service, and a sort of geocoding tool. I've rejigged the code so that adding a different (XML) output format to these involves just writing XSLT and putting in a new value for the "mode" parameter, rather than fiddling around with C#, recompiling and all that. All feedback most welcome. But don't bug me about a collections API!

To start you off, here are links to one request from each service.
  • events API. This won't work forever as the events will expire. Uses the format that Upcoming outputs with xCal, DC and geo extensions
  • publications API
  • the geothingy converter whatsit

The browser on the server

I've been wondering about the possibility of running JavaScript outside the browser, in fact as part of the web server. Of course, old-style ASP could be written with that language but that's not really the same - what I want is the ability to take and manipulate objects on the server that you'd otherwise be expected to work with in a browser context. I was thinking initially about JSON - I know that it's perfectly possible to use JSON from other languages (libraries exist for PHP, Python, .Net etc) but wouldn't it be better just to do it with a JavaScript engine? And then I thought, well, Mozilla's engine would be the obvious thing, I presume they've built it in such a way it can run in other contexts. So I started googling and obviously this is a very well-trodden trail that I'm just late in exploring: there's loads of stuff out there. I've not checked out any of it properly but thought I'd put some links here in case anyone else is toying with the same idea, or is prompted to now.

Incidentally, one of the things that's nice about JavaScript is that it's all focussed around the DOM, unlike many other languages, and I'd think it's pretty forgiving too (depending on the engine). All of which makes it a good candidate for screen scraping. And one thing I've not yet found is a way to tie this into .Net nicely

Made an API

No, not a collections database interface, Mia's onto that one. But I'm scheduled to work on the events database about now, and with the mashup day (now full up, I think) coming it seemed a good idea to grab a day and finish off this job. For ages we've had an RSS feed which gets a lot of use, including consumption by sites like dockland.co.uk, and of course search functionality onto the events web pages, but the feed is (a) a bit basic and (b) just shows everything for the next 14 days.
I wanted to turn the static feed into a properly searchable REST interface, as well as load it with more good data. So I plugged a hole whereby only a start date could be specified, put in filters for audience, event type, and keyword (like the web pages), and neatened up the separation into XML. Now it can be churned out in raw straight-from-the-database XML or in RSS 2.0 with extra hCalendar. I've got a couple of tweaks to make (adding in addresses and geo data) and then will invite the world. The plan is that you can set the format in the query string, so RSS2 will be one option but so will xCal (as used in Upcoming's XML) and whatever else - it'll just pick up a stylesheet and apply it on the fly. There are more filters I could apply, and documentation to do. Then thinking about pagination with OpenSearch extensions... and then who knows. Most of it will wait, so I'll post soon with the details on the where and how.

WHATWG, RIAs and online/offline applications

TechCrunch has a really useful survey of the current status of browser storage, what it really means, how it relates to WHATWG's work on HTML5, [Google] Gears and current and forthcoming browsers. It's explained a lot to me and given me at least the idea that WHATWG's work is coming to something. Looks like we can't yet know quite how the RIA technologies like AIR, Silverlight etc will tie in with this, but the article ends on a very optimistic note about being able to programme to one API since the only mature product (Gears) should be fully HTML5 compliant. All good.

Freebase - a LOT is interesting about this

Alex Iskold (again) gives a great explanation on ReadWriteWeb of what Freebase is, how it works, and where it fits into the Semantic Web. I've got nothing to add, except that I've realised I must explore it, but it's blindingly obvious that this is one possible path we could explore to binding together information from multiple museums and linking it to more broadly understood concepts and data from outside that domain. I love the sound of the query language the API uses, too (metaweb query language, MQL), it's so obvious and yet so novel and useful.
Iskold follows up with another post putting Freebase and others into a broader context of semantic search: Semantic Search: The Myth and Reality

Google Earth in your browser

GE in your browser: about time too. Just wanted to test it, so using the utility that O'Reilly Radar pointed to I've embedded GE below to show some more pics, this time from Chalkney Wood in bluebell season. They're not all that well placed, it must be said!

You'll need to install the plugin, of course, and its currently Windows only, and for the main browsers.

Screen-scraping and POSH

I hesitate to put this post in thing-versus-another-thing terms, and I won't. For one thing I think that both the alternatives I'll discuss are not in opposition but compliment one another. But there are strengths and weaknesses to each.

Mike Ellis and Dan Zambonini recently unveiled hoard.it, which Mike showed me a draft of some time ago but which looks like it's come a long way. Hoard.it is basically not unlike Dapper in that you can teach it to screen-scrape sites, but instead of basically making an API onto those sites it will ingest the data and then offer it up through an API once scraped (not sure if this is live yet). It can screen-scrape by spidering specified sites. I don't know if their other plans are yet implemented but they also hope to let you scrape a given page via a bookmarklet, and to give the app the ability to match up a given page to templates in its memory. What they're showing is more targetted than the application is capable of because it's aimed specifically at gathering museum collections data, and displays it all appropriately, whereas of course the whole screen-scraping thing that hoard.it is capable of has many more uses than that. It's cool, and in typical style it's an example of "just get it done" tech designed to get something useful underway, even if it's but a stepping stone to something else.

Making templates for a screen-scraper is one way to gather data from the "surface" of the web. Another way to achieve something similar is to embed some sort of standardised "meaning" in the HTML. Microformats are one such route, as are various other flavours and approaches to Plain Old Semantic HTML (POSH). Early last year I put aside my effort to test this idea out for indicating and gathering museum objects. I called it Salad Bowl but Gathery has taken its place as my favoured moniker. Nothing else has changed in the last year, though.

Gathery is a test of two things, really: firstly, the idea of using microformat-like POSH for museum objects; and secondly, the dream I've long had of being able to gather things I liked as I explored the web. Technically there are three elements, I suppose: the POSH; a bookmarklet to identify any number of objects on a page and pass your selected one to the application; and the application that takes that data, processes it (including looking for better quality data at a "home" URL - say, an OAI-PMH source) and lets the user do stuff like tag and describe it, and ultimately feed it back out. It's functional but not complete (I laid it aside because I was unsure which direction to go with the POSH, not to mention being quite busy), but in many ways it's similar to what Dan and Mike are doing with hoard.it. When you boil it down, the differences come down to the screen-scraping as opposed to the POSH approach.

So I've been trying to draw out the pros and cons of hoard.it and Gathery (the latter will probably never come to anything), but essentially it's a comparison of screen-scraping and POSH (though a pro for one isn't automatically a con for the other). Bear in mind that I have at the back of my mind a set of questions relating to how we move towards a semantic web for museums, as well as how to achieve the things I've always wanted as a user, namely an easy way to search and gather material from collections all round the web. Obviously my comparison is based on a good knowledge of what I built and pretty thin knowledge about hoard.it, and since I've not publicised Gathery it's not easy for you to test the comparison (though do ask for the URL if you're interested). But take think my pros and cons as relating to screen-scraping and POSH and let me know if you think they cover the important aspects, and tell me where I'm wrong and what I'm missing.

Gathery (or microformat/POSH approaches)
Pros:

  • m-object, The POSH I drafted and tested with Gathery, has two levels: content indicator (points to the "home" URL where the best content resides, includes a GUID and an institutional identifier); and content carrier.
  • content carrier is optional, so it is not necessary for content to reside on the page: the author can choose to do no more than indicate that an object's record exists somewhere else
  • authors using explicitly-chosen standards should be less fragile than screen scraping
  • Gathery is focussed around user behaviour and goes where they go, including outside museum sites. If someone embeds in a blog or Wikipedia a pointer to an object on the Museum Of London site, it can be submitted to Gathery which will go to the "home" URL to look for the fuller record
  • content owners get to decide the relationship between their data and the fields in POSH of whatever sort (a microformat, the m-object quasi-format I dreamt up, RDFa etc)
  • data content can be in any number of forms other than the m-object snippet on the page itself

Cons:

  • POSH or microformats require explicit choices and action by website owners, whether they are museums or private individuals etc.
  • the m-object content carrier part is inflexible [whereas screen-scraping is in some respects as versatile as the scraper's designer wishes]
  • content creators have decided how to align their data with standard fields, as opposed to the gatherer (see also pros!)

Hoard.it (or screen-scraping approaches)
Pros:

  • scraping of (well-structured) content requires only that the template be built: nothing extra is required of the site owner
  • it is adaptable to fit the available data and the preferred data model of the operator (the ingesting application), and to an extent the template creator
  • clumsy, semantically overloaded HTML is avoided
  • hoard.it includes a spider (though of course this is just as possible for a POSH-based application)
  • when the bookmarklet is available (if it's not already) then hopefully users will be able to gather data from wherever, and apply existing or new template to it

Cons:

  • screen-scraping by definition depends on content at the surface of the web i.e. on web pages. All the content you wish to grab needs to be there
  • data is rarely structured on screen in an unambiguous and subtle way. Data that is structured for machine-to-machine communication or indexing is. Using this where possible would therefore be better
  • the scraper template designer tries to fit what they find to the data model they have, whilst the data's owner may have other ideas about the best fit
  • fragile (part 1) - a change of HTML breaks the template and may make previous data models for an item unworkable, breaking the logical link between versions of an item
  • fragile (part 2) - a change of location breaks the knowledge of an item because there is no concept of a home URL or a unique identifer.
  • if users are declaring their own templates, there are no common standards for the data they are ingesting

This is all a bit of a muddle, and perhaps it's unwise to mix up discussion of two particular (and very alpha) applications with discussion of the two broad approaches they take to similar problems, but for me it's a good way of teasing out the merits of each. I also think that there's scope to combine them - for example, whilst hoard.it might continue with a gunslinging, screen-scraping, get it done approach, it could also advocate to museum web techs that they use some minimalist POSH (a bit like COINS) to uniquely identify their objects and give them a "home URL", ideally an end-point with proper structured data that it could also ingest (CDWALite or whatever). It could demonstrate the merit of this relatively easily. In this way something that didn't require too much from authors could add an extra dimension to an application that requires nothing from them at all, other than nice and regular HTML.

OT: Leuven photos

As I said, Leuven is a beautiful place. In truth the only chance I had to explore it (having arrived at half past midnight, and rushing back to the station before the meeting even finished) was between leaving the hotel and the start of the meeting. I took my time, though, and snapped incessantly on my intentionally circuitous route. This slide show is the best of it. Hope you like it. They're all mapped, too, if that tickles your fancy.

Good 'Times for APIs

Not quite as abstract and "strategic", perhaps, as Reuters' OpenCalais play, but the news that the New York Times is opening up as an API of some sort is significant. They have to make money from their content, and yet they look like they're giving a lot of control over it to other programmers. What stronger example could one wish for to argue that it's good to open up access to content that we actually want people to use as fully and freely as possible?

RWW's article points also to a post that I didn't remark on first time around: APIs and Developer Platforms: A Discussion on the Pros and Cons.

Slicing the market mini-, sorry Micro-update: TO'R on MicroHoo

In his piece MicroHoo: corporate penis envy? Tim O'Reilly makes lots of interesting arguments concerning where Microsoft should be putting its energy - as far as he's concerned, it should forget about trying to grab a slice of the search market and focus instead on building the internet operating system. For Yahoo!s part, it should realise it's the number one internet media company and make the most of it. There's lots here to chew on (and object to, as Michael Arrington does here, and I happen to agree with him and Jakob Nielsen that search, especially semantically intelligent search, is far from ticked off), but the paragraph that grabbed my attention concerned a couple of other players:

Apple's apparent success with an "own the stack, from the device to cloud" strategy is misleading. With both the iPod and the iPhone, a key element of success is precisely the device's openness to what Apple does not own. Imagine an iPod where you could only buy music from the Apple music store instead of ripping your own CDs (this is Amazon's mistake with the Kindle). Imagine an iphone without the Safari browser (opening a world of web apps to the phone) or the Google Maps application. Apple owns key elements of the stack, but it's a permeable stack, and getting more so.)


This is handy material for making the argument that museums shouldn't try to (or be required to) "own the stack". Far better to focus on a layer in the stack and make it permeable. iTunes (the music store) is clearly an example of trying to corner a part of the market outside Apple's home turf, but (a) they're big and ballsy enough to try it (and who else was doing so effectively at that time? Aside from Napster...) and (b) the core offering is still actually the hardware, and it allows you to acquire music by other means. Amazon and Kindle is interesting too. Perhaps it's too early to say they've made a mistake, though they probably have. I doubt it will stay closed and succeed. Nevertheless, as I acknowledged before, they are making a grab for more of the stack. But let's not forget, they're HUGE!

What can we learn? Well there's that point about openness/permeability. If we must insist on claiming the vertical market from top to toe, from collections management system to the end user's screen, then at least make it permeable and open. Otherwise your carefully grown fruit will wither on the vine, forgotten and increasingly past its sell-by date.

Leuven that aside...

I'm not quite sure where to go with a pun of profound lameness even by my own pitiful standards, but I'm giving it a Creative Commons Attribution Sharealike licence in case anyone can make it pay. Not holding my breath.

Anyway, to the point: bloody hell, railways! Well there are other points, but just wanted to get that off my chest. To Beligium by Eurostar is lovely, unless there's a strike. Eurostar to their credit did all they could to help, moving me onto a later train in the not-quite-certainty that it would get past Lille. They also told my hotel I'd be late. I got there, well, the right side of dawn but the wrong side of midnight. And travelling back I had the more day-to-day joy of British trains being titsup. Not forgetting Junior puking on the journey to the train before all of that. I must have offended St Christopher or something.

But the travel trauma was all worthwhile. The meeting itself was really good and I would love to return to Leuven, it's a beautiful and tranquil place. Imagine a city centre so quiet at rush hour that most of the traffic consists of parent cycling next to their infants on the way to school.

My take-homes from the meeting were many. Here are some.
  • There seem still to be divergent thoughts on whether there will be a record page, although I think it's looking very likely (as seen in the maquette). This means different things for different types of institution and material. Where the original DO on the institution's website is more than an image of moderate size, the visitor will have a motivation to leave Europeana and visit the original. For films and audio this will be clearcut. For assets where the surrogate is in any case an image, they may be less likely to leave. Perhaps this depends upon the size of the largest image that Europeana will show. It does bring home, however, how vital it will be to demonstrate to content contributors that there will be superb reporting of usage of their material on that site.

  • linked to the previous point, if EDL hosts only image surrogates (and occasional small derivatives of multimedia?), it keeps its costs down and traffic to institutions high, but we must keep in mind quality control of the originals hosted elsewhere - what will be acceptable standards for different formats, and how do we control this when they're actually never ingested?

  • a drawback to the plan of ingesting only thumbnails is that for institutions with no existing online presence this is not very helpful. Perhaps EDL should offer a premium service, or one for limited numbers of surrogates per institution, where they can offer to hold a full size image/media asset and display this in a modified details/record page. I'm very keen on this, as a means to attract the participation of tiny museums by, essentially, offering to get them online for the first time. The current model presupposes that every partner is already online - we need a 180 degree turn on this. It's also possibly a modest source of revenue.

  • EDLLocal is obviously the plan to encourage the participation of the minnows at the moment, and I need to find out more about this. Nevertheless, if it still presupposes a web destination outside of Europeana for all DOs it's not enough, IMHO. We need to see just how low we can set the barrier to participation, and how big we can make the reward. Rather than requiring a URL for each DO, it would be better to be able to take whatever a contributor can give - a DVD of images and a spreadsheet of metadata, say - and offer them

    • fuller record pages on Europeana

    • API access and code fragments for dropping onto a blog or whatever

  • I like the idea of using a wiki for UGC related to objects. It has the advantages of being

    • cheap and out of the box

    • very easy to create new pages

    • EDL GUIDs/DOIs usable for page names

    • microformat/POSH friendly?

    • familiar to many

    • clearly distinct from the "authorised" content

  • The new home page that Jon Purday showed looks like progress. The concept is a good step, the graphical side isn't finished but getting there

  • There was plenty to read and discuss about reorganising EDL for the next phase of the project, the build of version 1.0 (first we have to launch a series of prototypes). It's too early to talk about this.

  • We worked on the vision and mission, which was quite fun and threw into relief some differing ideas of what the whole thing is about. Personally I like for a vision something like: Europeana.eu: culture and heritage, connected and shared. It's short, it emphasises both the connections being made between knowledge and the sharing of this with people.

  • Money is tight, realistically EDL will be relying on a subsidy of some sort for a good while to come, but there may be some good commercial opportunities. These needn't conflict with either the ownership of the source data and digital assets by contributors, nor the public service/public good ethos. The semantic graph derived from the combined dataset will belong to EDL, and this could be very marketable. I have to work up ideas here, I have OpenCalais in mind as some sort of model.
One other outcome was that the cabbie who finally got me home solved a UFO mystery I'd been intrigued by for a few months. One evening last autumn I watched a string of lights for about ten minutes as they emerged over the horizon and slowly rose through the clouds. Either it was something fast but a long way off - I was thinking shed-loads of planes from one of the Suffolk airbases - or actually as slow as they appeared and nearby. Turned out they were the latter - a whole load of candles floating under balloons, released from Gosfield School to confuse those who Don't Even Want To Believe But Are Intrigued By The Lights

To Leuven (expenses paid), but who will pay for EDL?

Tomorrow sees EDL's working group 1 meeting at the Katholieke Universiteit in Leuven, not far from Brussels. Quite exciting to be visiting, albeit fleetingly, a place that played host to Matsys, Bouts, Erasmus and Vesalius, amongst others (not to mention, apparently, the infamous AQ Khan). I'm looking forward to attending, though with no expectation of being able to contribute a lot since this group covers different ground to the one I've worked with up till now. I'm not even sure if I'm part of the group or simply in attendance. Anyway, the meeting will look at progress with Europeana so far, and consider the business issues facing it, particularly how to move to phase 2 (i.e. following the prototype, to be launched in November) and how to build a sustainable future. Working my way through 100-odd pages of reading matter in preparation for the meeting, I'm struck by how big a challenge it will be to find the necessary ongoing resources, but also the fact that they are tackling the problem head-on and examining a wide variety of options, from direct subsidy, through subscription by contributors or users, to corporate partnership or sponsorship.

A significant factor in the search for revenue-raising avenues is the fact that Europeana is not going to be a content owner in any significant way, but rather a broker/facilitator for accessing content owned by others. One possibility that I believe it could be worth exploring for two reasons is some form of partnership with a search provider. Yahoo! may be a bit too distracted to talk at the moment, but along with Google could be productive partners. Both sides could benefit by working on an interface and aligning their data structures, and EDL could perhaps offer quite a bit to such a partner in terms of preferential access to the semantically enriched data it will hold. This might be directly to do with searching the resources in EDL, or it might be, say, helping to clean up datasets of people and places. In exchange, maybe either some cash or technological assistance? Perhaps some of the semantic-y startups currently taking wing could also be interesting to work with, but they won't be as well resourced. Cultural heritage organisations have a lot of knowledge and context to offer here so maybe there's a business model to be had.

Yay! Follow the Search Monkey!

Well, rock'n'roll, looks like Yahoo!'s* Search Monkey is going live today. Apparently this will allow us as site owners to (cribbing from RWW's report) "share structured data with Yahoo!, using semantic markup (microformats, RDF), standardized XML feeds, APIs (OpenSearch or other web services), and page extraction. " On the basis of that data, other developers will build apps and users will enhance their search. This seems to be precisely the sort of thing we wished for in the SWTT (in fact legendary Mike Lowndes pointed to earlier signs of this move last month). It's also what I had my doh! moment about last week.

So if it's what I hope it is, we can co-ordinate with others in the sector on some standard fields (and keep it simple initially), push our content into Yahoo! and build apps on top of their search engine. My reservation would be that at the moment it seems to be about building either "Infobars" or "Enhanced Results", but perhaps there's something more API-like and programmable there, or on the way.


* is this the right way to punctuate the possessive of that annoyingly-punctuated name? Answers on a postcard (to Jerry Y!ang).

Microsoft's prototype chirpy cheap cheap multi-touch interface: Touch Wall

No point rewriting this post on RWW, this is cool though. Watch the vid. Shame there are not plans to "productize" now, but the cost sounds low and the interface intuitive (and obeying the conventions developing around multi-touch).

It's also worth looking at the Touch blog now and then. It's mainly about near-field communication (lots of RFID) but also touch interfaces (nothing on this MS thing yet).

Digital archiving and risk management, that's DRAMBORA's game

The DRAMBORA project is blogged about on ULCC's da blog. It's another initiative in the digital curation/archiving community that could have outputs that can be directly transported into good management practice beyond formal archiving.

The Passively Multiplayer Online Game, PMOG

TechCrunch led me to the Passively Multiplayer Online Game, PMOG. Looks like it could be fun, and I wonder if it will turn out to have a bit of overlap with the "web quests" idea of the sort that NMOLP was apparently inspired by (not much point clicking that link, though, it's password protected. Google it and look at their cache if you like, though :-). Just keep escaping the login windows).

The Yahoo! Internet Location Platform

Brady Forrest writes about the Yahoo! Internet Location Platform, which sounds very cool. Couldn't be simpler, really. I'll have to have a look at just what sort of entities that relate to MoL have a WOEID (What On Earth ID), but doubtless there's lots we can do with this. If we can find the time...
He also points to this for how it all ties to Flickr.

Slicing the market

To follow up my recent posts on the 21st century museum and the National Collections Online feasibility study, here's a little more about the question of how funds are allocated by bodies like HLF, and how come we've tended to see them requiring digitisation projects to run from end to end, from digitisation to web publication.



I don't really know enough about the programmes that were run in the past like, for example, NOF Digitise and the HLF (still funding today). However from the projects that I do know that drew on these funding streams, it seems clear enough that concentrating on digitisation per se was never enough - a user-facing product was expected. These did have a sort of aggregated interface (http://www.enrichuk.net/, now pointing at MICHAEL UK) but not really what I've got in mind.



It's quite understandable that this practice persists, indeed there is a good case for it. For funders, they want to see direct user impacts, and a website that can generate stats is nice for that. For museums, well they have a two-fold role - to hold and to document their collections; and to research and interpret them for various audiences. Naturally, then, there will be forces within them urging them to do something with the stuff they digitise, and do it now. The downside is that this has led to fragmentation of the materials digitised for these programmes.



My argument is that for modest sized projects it's not good to spread yourself too thinly trying to do everything, but instead to concentrate on part of the value chain. It's a straighforward architectural thing, and essentially I've realised that I'm just asking for a shift in the assumptions of funding bodies from demanding vertical slices to demanding (contributions to) horizontal slices - in short, to encourage the building of a strong sector-wide layered architecture. Vertical businesses deal in multiple (if not all) links in the chain from production to consumption. This is not really suited to much of what we do. Indeed even behemoths like Amazon don't yet do this (though they a strategically building out from their core business) - they don't actually write books or commission, edit and publish them, print them, or market them, or at the other end deliver them. They flog 'em and dispatch them, and act as an agent for others to do the same.

It's crazy to ask, as a precondition for funding, that a museum or partnership does the whole chain from digitisation and record enhancement, to search engine development, perhaps aggregating records, through to building the user experience as a website, a game etc. Things get done again and again and again, effects are diluted, money wasted. Lots of good stuff will still be made, of course. I don't know what this horizontal architecture would be like, though just possibly we can see parts of it falling into place with PNDS and the Integrated Architecture, and I don't know to what degree it would play a part in many projects in which UK museums engage, but I'm just suggesting that instead of HLF, for one, getting hung up on projects doing the whole end-to-end thing they should support us in coming up with a model to slice the market differently, working on one step at a time, and recognising that the very process of creating the digitised content is a valuable step that is somewhat independent of the creation of an audience-facing instance of it. Vertical slices make silos.

For more on slicing and dicing see here. Shalom.

National Collections Online: why, what, how...in fact, ?!?

Friday afternoon we gathered at the Science Museum's Dana Centre, perhaps two dozen people sampling a variety of disciplines but all, for one reason or another, interested in the National Collections Online project. This was a workshop for the feasibility study being run by Flow Associates (Bridget McKenzie and Mark Stevenson) following up the discussions they've had with, presumably, all or most of those there. NMSI and the V&A had good representation, not just techy and new media but curatorial and from the collections data side. The National Maritime Museum, the third museum partner in the project, had a couple of representatives too. Culture24 is another partner, and Jane and Jon were there. The NMDC, who I take to be the initiating partner, had no direct representation but wil hopefully learn the lessons anyway. The rest of us included e-learning experts, a couple of people from other museums and the Wellcome Trust, Ross flying the flag for academia, Ben Hayman of Lexara that for the commercial sector, Nick of Collections Trust, Jill Cousins from EDL (which I thought was brilliant, unfortunately she couldn't stay until the denouement but I have a feeling that her presence may have swayed some sentiments in the direction of EDL), and finally Tom Steinberg, director of mySociety. A very interesting crowd.

The biggest problem with the session was, I guess, exactly the same as that which it was trying to address, and perhaps will have helped us to break through it before the next gathering. That problem is the vagueness of the project, which made it almost impossible to talk incisively about it. Someone mentioned a 10,000lb gorilla at one point; all I could see was a big cloud in the middle of the room, who knows what was at the heart of it. I've not talked about NCO before so I should do the basics: Flow's inquiry is into the "viability of an online resource to integrate national museum collections", and perhaps we can orient ourselves as to what this might mean by the well-known points of reference that they have mentioned: CHIN/CCO, CAN, culture.fr, Artstore, Powerhouse. It seems that many people said "not a portal", which was the common response at the session too. Given this, we both needed to decide what we were talking about if not a portal, and know that in advance to make much progress on questions like whether a "single point of access" would be of use to various audiences. This isn't a criticism of how the session was run, it was sure to be tricky as a natural consequence of the fact that, even before the project properly starts, it maybe engaged in a major change of direction (and this is the time to do it!).

Anyway, it was a useful process and it did seem to bring out a good degree of consensus on the unsuitability of an old-skool "portal" approach. I took away a couple of key points though, including a useful reminder:
  1. Fiona Romeo made a remark that inspired a "doh!" moment in me: why not talk to Google about them ingesting our content directly? This time last year we were talking about this very prospect at the UK Museums Semantic Web Think Tank, and it still seems like a really good plan (Yahoo! too, especially since they seem at least as keen on adopting semantic technology). Still, somehow, I'd stopped thinking about this line of attack having been concentrating on the opportunity (or threat, if done badly) offered by EDL. And in the session I didn't shy away from pushing EDL as the obvious place in which collections data should be aggregated, so as to scale to all museums and not duplicate efforts. I argued that NCO should wait for this to firm up before deciding what to do that would compliment or build upon it. However when Fiona mentioned the prospect of working with Google, I realised that over the last 6 months of talking to EDL about how to make sure that it wasn't seen as irrelevant by museums, I'd started to forget that it needn't be the only path down which we go to achieve our goals - just the one that grabbed my attention late last year. I think that the two approaches can be complimentary, and in fact EDL itself would be well advised to talk directly to the search providers about their ingesting structured data. NCO could, in theory, provide something of a breakthrough that would be genuinely extensible and scalable. This would also put the lie to one of my contentions, which was that there was little point in doing something that only involved a small number of nationals. On the contrary, if it opened a very wide door for cross-collection search as this approach might, it would be very worthwhile.
  2. I had a moment of clarity, which followed on from the recent hooha on the MCG list concerning the disappointment or otherwise of the NOF Digitise programme. One of my arguments was that it would be better to make distinctions in projects between those that do digitisation, those that build functionality, and those that build user experiences. I realised that I'm talking basically about slicing funding differently, changing from vertical to horizontal slicing, and that it's not unlike talking about markets. I'm going to post separately with more thoughts on that.
  3. We had useful input from Tom. Though he was kind of preaching to the converted about the idea of making our content as widely available as possible, it's not surprising, and he also furnished us with some useful parallels and metaphors. From our later chat at the pub it's clear enough that he's as keen on the lightweight dissemination of semantic data as I am (albeit sceptical about the Semantic Web - but then in a sense so am I, it's semantic technology that is making the headway, and there are riches to be found there that do appear to be speeding us in the general direction of a more semantic web in any case)

The slightly better shape we're in

Well one thing I didn't mention yesterday was the good news, which is that Friday saw the official launch internally of a new set of guidelines for "digital programmes". This is something that Pete had been working on for some time, doing exactly what I've been arguing for from the point of view of planning, not just for current usefulness, but for longevity. That is, he makes explicit links between the strategic and business aims of the organisation, and our digital activities. From there he turns this into a set of principles or activities that must be followed/carried out by "any member of staff considering the creation of a digitally based resource either as an item in its own right or in support of an exhibition, publicity campaign or event ". It's a very thoughtful document and a really big step for us. In fact it's pretty big full stop - 25 pages big.


Another part of the document outlines the planned ICT committee (heavy on the web), and gives a dozen strategic considerations that underlie the document such as centralised programme assessment, interoperability, technical fit, and some interesting ones like flexibility, which relates to the ability of potential partners to respond to our needs.


There's plenty more in there. There are still holes to fill, but I'm hopeful that this document will make a difference to how commissioning takes place from now on, with fewer nasty surprises for us and better allocation of resources for all.

The shape we're in (with a musical digression)

Today I'm still making the most of the quiet to dig into my vinyl and I'm working to the sounds of the german underground, mainly circa 1970-75. Right now, though, Phew (1981). This just so blows my mind. Can fans must have it, and they can get it on CD now (perhaps I will too, it's so hard to get at my LPs most of the time). Given that I've been writing about what our organisation needs to do to get its digital act together perhaps its good that the previous listening has been pretty calming: Alpha Centauri, Tone Float and Outside the Dream Syndicate (not that mellow, actually, the last one). Phew has lovely peaceful moments (like Dream, now), but a driving, anxious motion to some tracks too (Signal). The legendary Roger of defunct Revolver Records in Bristol sold me my copy, I don't think I've thanked him enough and probably never will, but thanks anyway, Rog.

I've been thinking about the holes in our policies (notably concerning the preservation of UGC - we may not want to bother, but we have to at least formulate a policy towards it), and I've been looking back over the 6 years I've been there and thinking about how our responsibilities have developed. We need to work up a business case for a larger team, and perhaps one of a different shape. Frankly it's a no-brainer, but the case needs to be made and it's a good exercise to outline those changes. We also need to work out with the Godot-like web committee (I'm sure it will be along any day now, with purposeful stride and a keen sense of what needs to be done) quite what role we want the web folk at MoL to have. There is a wide range of things we could be doing, and right now we try to do most of them, with some key exceptions like web design and rich media work (Flash, video), which we always farm out. But we do too much and can't always do it properly, and I feel the need right now to consolidate, to work on our infrastructure. If we can decide on exactly what we should be done in-house, and what can be effectively handled out of house, then we can get and give a clear idea of just what resources we need. Right now we have our content manager Bilkis (the one net gain since 2002), Mia, who does a lot of web work as well as various databases, and me, essentially just web.

Personally I reckon we need more people in the team, but there are alternatives, even if they're idiotic: the Museum could decide to draw in its horns and use our expertise just to commission, integrate and manage third party work, as well as content. We certainly do plenty of advising on this at the moment, and most of the vendors we've used recently have done great work for us (please drop me a line if you want to know whose work was not up to scratch), but I'm one of those who think the core work of a museum web team must also include taking care of the plumbing and probably building/running the core CMS too. Perhaps when I've finished my musings I'll post a proper list here of what functions I identify, what I think we should take into our remit, and what I think we should hand out. Best get on with it, then.

The MCG thread: 21st Century digital curation

Bridget McKenzie has blogged and kicked off a great discussion on the MCG list following a seminar last week with Carole Souter of HLF and Roy Clare of MLA. I've written a reply but as usual I do go on a bit so I'm sending a brief version there and putting more depth here.




There are so many strands to this exchange that I want to jabber about so I’m going back to the start – Bridget’s post. Bridget, if I get your drift, yes, I agree: there is a balance to be struck between the effort put into basic “digitisation” (though I think there are various ideas circulating about what that term implies) and interpreting our digitised collections, and I’m not sure we’re being helped to strike the right balance at present. Raves and gripes about past projects aside, it’s how we spend the scant funds now available that bothers me. Going from a time of relative plenty to a time where most budgets are Spartan rather than Olympian, how do we plan clearly how we spend them?

I’m torn. On the one hand, I get the sentiment which says, we need to be making things that people will enjoy, with some sort of mediation and aimed at well-defined audiences, just like any exhibition or public event we host. I accept that HLF amongst others want their funds to be used on things that we don’t automatically do, things that aren’t our “core activities”. And I take Dylan’s point that, when resources are scarce (which is always), demonstrating (actually, having) impact is really important. But….

On the other, I would suggest that digitisation being referred to as a core activity betrays the fact that it is indeed now something we have to do. The trouble is, it may be a part of our core work, but it has never been core funded (at least not in terms of funds additional to the pre-digitisation days). So it’s a cop-out to say “it’s really important, and therefore we won’t pay for it”. Who will, then? Until our core funders, whoever they might be, come up with the cash to do this newly core activity on an ongoing rather than project basis, we’ll have to act as though it’s not “core” and go begging precisely because it’s so important. But apparently HLF think it’s important enough to not fund it too, so we’re stuffed. I’m glad to hear that in Birmingham at least there digitisation is seen as something to drive with internal funds, I guess HLF are hoping more places will go that way.

The important thing that NOF Digi did (along with other HLF and DCMS funded projects) was get a load of collections records in some sort of order and snap some nice shots of the objects (which seems to be commonly accepted as equating to the “digitisation” of a typical museum/gallery item – making a good record and a decent photo). All the other stuff isn’t flim-flam – for those many users that had a great experience of Port Cities and other such projects, that experience was in no small part due to the contextualisation and linking built on top of the vital digitisation effort. I’m sure that BMAG’s Pre-Raphaelite website will be great, but as Rachel says, the payoff is much more than whatever users it attracts. Like an exhibition, the mediated experience will be more transient than the collections (physical or surrogate) on which it is built. We can’t equate web-ready records and surrogates with physical collections, but nevertheless they are the bricks and mortar from which our public-facing offering is built, and they will last longer than the wallpaper, lighting, video games and Persian rugs with which we make it “engaging”. Besides, sometimes all that stuff ends up seeming really forced just so we could secure the funding. Kind of like the way I’m now listening to Paul’s Boutique and hoping to find a clever excuse to quote some lyrics in support of my argument!

Unsurprisingly, then, I come out on the side of those like Bridget, Mike (E, not D) who argue that investing in the fundamentals in such a way that they can be built upon in future is the way to go. To me this means, basically, getting those records and surrogates done irrespective of anticipated clicks: if the object is worth accessioning, it’s worth recording properly. Getting that content into some public-facing form is, frankly, less vital, and we need to be considering intelligent ways of doing it. Building stuff in such a way that others can do good things with it is a step in that direction, which is why I’ve been pinning my hopes on EDL doing the Right Thing with an API. If this works the right way, any size of museum could contribute content and use Europeana’s centralised brain-power to do all the hard work. Then the basics are done, the mediating content can be tied in to it. But “digitisation” is the essential part. Like Mike, I’ve told both EDL and NCO (via Bridget) that they could reasonably drop a user interface altogether if they provide for other people to programme against an aggregated collection, but conversely a public UI without and API is pointless. I say “Rapunzel, Rapunzel, let down your hair” [see side 2 for details]. And Nick, the way you describe the vision for IA is very encouraging for this precise reason. Wish we’d had the chance to talk about it t’other night!

Stephen Lowy also raised the term sustainability. What he described is better termed preservation to my mind (although successful preservation needs sustaining…), but sustainability is at the core of this, and for this we need to make a clear distinction both conceptually and architecturally between the layers of the “digitisation” – the records and surrogates ([collections] data layer), access to them (the layer of functionality), contextualisation (a mediating layer of more content), showing them (a UI layer), perhaps including engagement with the resource in Web 2-ish ways (an additional set of social layers?). We shouldn’t be required to provide all of these parts; it’s ridiculous, even with multi-institution projects. Of course we often want to anyway, but for major funders to say, “we are only interested in helping you with the basics if you’ll build all the other layers too” is dumb.

I should add that I do actually believe that interpreting and being creative with our collections (and in fact going beyond them) is also a core activity of museums, and this obviously carries into the digital realm. To take a current famous example, Launchball, which I had a riot playing with my 5 and 7 year old yesterday: this is exactly what museums are for, but it could have been (relatively) rubbish if it had been compromised in the way Mike describes, perhaps tacked onto a digitisation initiative for the sake of funds and shorn of its purity. It has all it needs: food, sickles and girls

Mike again: “cash for sustainability is either not considered or frowned upon by funders who simply don't recognise that this is an absolute requirement in any successful (web) project.”, and Tehmina also wonders what measures are in place to avoid a repeat of situations where there is no planning for maintenance and continued content development. They’re right. At the start of each project we must be stating (a) what’s important about it (b) how long we want the important aspects to last (c) what strategies will be built in to assist this (d) what other potential sources of value the resource offers. This way we can build it appropriately (funds permitting) to ensure that we can indeed continue to realise value from the thing for the proposed lifespan. And once that period is over, we should also be in a better position to re-examine the resource, decide what’s still got potential to advance the organisation’s purpose, and maybe squeeze more value from it. And if we take the right approach to architecture, with conceptual and technical divisions between the layers, then if we’ve decided that one part is for a couple of years and another is “forever” we’ll be able to put out efforts where it matters.

Bridget asked: “what such lead bodies [HLF and MLA] should be doing to invest in 21st century digital curation?” Basically, I’d say, they should put their funds in three areas and realise that they need to be seen as separate endeavours
  1. invest properly in strategic, sector-wide initiatives like the Information Architecture, that one would hope will do the plumbing job we need, and feed into EDL (and beyond?). Fingers crossed for this one.
  2. support simple digitisation to create the straight-ahead content to go into EDL and/or IA. It’s still got to be done. If it’s not support with funds then MLA must ensure that digitisation is recognised by those providing the core funding as a core activity, and is adequately provided for on an ongoing basis. Not too optimistic.
  3. yes, still fund us to build some imaginative and innovative, born-to-die experimental exciting digital stuff aimed directly at the public. Who knows? Maybe.
  4. and funds need to have the right strings attached. Maybe this is sometimes related to “impact”; it should also be about identifying the “sources of value” in a resource, budgeting realistically for supporting them for a specific period, and planning for the end of its life.

Can you tell it’s a holiday weekend and I’m the only one at home?

PS. About those sickles: sorry, the Mummies also made it onto the turntable.

PhotoLondon, genealogists and GEDCOM

Since I discovered that at least one family history website was sending users in the direction of the newly belatedly launched "Database of 19th Century Photographers and Allied Trades in London: 1841-1901", I've been thinking more and more about how we can serve this audience.

GEDCOM (for which I guess this is effectively the official homepage) seems to be the data standard of choice for interoperability in genealogy software. The latest non-XML version dates to 1995, but although its mormon keepers have been using the XML form for several years now (it was published in 2002) apparently none of the software out there in general use supports it still. How tragic is that? I guess in the museum world we're not quite the worst example of data standards paralysis! Anyway, if it had to be that which I would offer to the millions of family historians out there, so be it. It would make a lot of sense, though, to talk to that audience a bit, which I started to do on this thread. Useful feedback, not just on the worth of offering GEDCOM at all, but reminding me also of various things I'd forgotten (maybe overlooked) about that site. Copyright, sources, addresses (we have lots more structured data than is visible there), all things we could improve (given some resources).

It all ties in with an announcement this week from Stephen Brown to the MCG and MCN lists of the launch of Exhibitions of the Royal Photographic Society 1870-1915. The data in this (and an earlier site) seem so congruent with the photoLondon data that it would be lovely to explore how they might be tied together. A case for large or small semantic web, for feeds and APIs, for literally pooling data, for imaginative use of search engines or god old fashioned web content creation and management...I don't know, but perhaps we'll explore this. And now I've remembered that some of our data is more precise and structured than I had recalled, perhaps the possibilities are that much greater.

Now to get stuck into some GEDCOM. I might succumb to the XML flavour, though because frankly that 5.5 version looks like a dog.

Broadband: have you tried it?

Well tonight of all nights is one where I simply have to blog at the first chance I get. I've been telling everyone that today I finally join the late 20th century, because up until now I was quite likely the last web developer in Britain never to have had broadband at home. Today, ahead of the planned date, it was switched on. Even before then my ISP (PlusNet) had doubled my allowance to 15GB/month, which should do for now...
Took me five minutes from unwrapping the router to being online (a little less to set up wireless), so it's no surprise that Fiona has been asking why it needed to take so long. Good question. There was an economic issue at one point, and then at about the time it stopped being one (prices falling, dial-up costs rising as we did more online and the modem got flakier and everything dropped to about 3kbps) it all became just TOO much for me to get my head around: so many choices, contract lengths, how much of what do I need? to bundle or not? And so on. So a good 18 months after getting the green light I finally get around to it and the whole thing is a breeze. Of course, it's too early to review PlusNet as yet, but aside from a slightly confusing sign-up process they've really impressed so far. I love the way they tell you everything on their website, so much more transparent than anything else I've seen.
As for broadband itself, well, to be honest I use it all day anyway so of course it doesn't blow me away, but what I hope it will do is have a profound impact on how I work and study. If I can work effectively from home at last and avoid a 2 hour commute every now and then; and if I can do my research away from the office, that will be all I could wish for. Speed is actually much less important than having no restrictions on what I can do and how long for, but fo course I get both. There's a ton of stuff I want to experiment with, too, which there isn't time for at work. Yippee!
So for most of you that might be reading this (but probably aren't) this is not new at all, and for me it's not really a shiny new toy (well, a bit). But it is a big change, and I'm dead excited. How millennial!

KML to go

Well I've finally bridged the gap between our site summaries (which have long been available online) and GMaps (likewise). I told part of the story earlier - the summaries that our archaeology service write are compiled into an XML document (processed out of Word via a macro...), and transformed into HTML with XSLT. But because the location data is always in OS grid references it's no good for online mapping apps (which all like latitude and longitude). So I've been trying to find a way to get lat/long for the sites (which number many thousands) in order to let us plot the data for World And Dog, if they're not otherwise engaged.

Step one was to get a way to clean up the TQ-style OSGB data. Step two, adapt code/write a web service to enable me to pass that lot in and get back latitudes and longitudes. From there I needed to combine the resultant XML with the original site summaries. I tried doing stuff with Yahoo! Pipes but it wasn't too keen on my XML, or at least it wouldn't show me the items. Anyway, instead of that I thought I'd draw both datasets into one XSLT transformation and output KML, which is what I've done today (thanks in part to the inspiration of Raymond Yee's great "Pro Web 2.0 Mashups" book from Apress). I would have liked to just pass in a single variable (year) and go through all these steps automatically but it wasn't worth the hassle since every step needed a touch of hand-massaging on the data.

The KML includes all the site summary descriptive content. Looking at the resultant Google Maps I see there are some glitches, like things in the wrong place, and things without coordinates, and actually I need to check out 1999 which has a fatal error somewhere. I don't have time to fix these right now, but overall I'm pretty excited: at long last, we have a nice mapping interface for the public to look at all those thousands of excavations, desktop assessments, surveys etc. that MoLAS has conducted since 1992 (but not 2007 yet). Well I say all, in fact some of those from outside the London area are not included.

Now I'm hoping that someone will come and do something cool with the KML. In due course I'll have a go myself, but if you come up with anything please let me know!

So here are links to the functioning maps. Save them to My Maps and do something with the result!

OSGB-lat/long web service for GIS

We have loads of geographical information. Trouble is, it's almost all in OSGB grid reference form, which is no good for feeding to apps like Google Maps. Worse, much of it uses old-style 100km squares (mainly TQ, which covers London). We've taken a couple of approaches to this - hand-making a few maps in Google (for example, our Olympics work is mapped here), and using batch processing scripts from ESRI or others to manipulate the data in the geographical fields of our archaeology database, creating latitude and longitude values to accompany the OS grid references. However there is still a good set of data that needs another approach - for example, our site summaries for the last decade and more are available online. These XML-driven pages contain only OSGB data. I plot them very crudely onto our own ESRI-based map application, but would much rather have KML to work with.

So to the point. I came across a great script on the Hairy Spider site that also runs a web service. I wanted to take this further so that (a) I could pass in lots of values, not just one at a time (b) it could handle the TQ-style syntax (c) not keep on hitting friendly Mr Spider's server. The code available is for the convertion from OS eastings and northings to lat/long only and I've not tried to reproduce his "proper" web service, but I do now have something that will work for my needs. I can pass in a querystring like
gr=tq709098,SW465987,tl123456,51232456,512300245600
and get back something like:



50.8618352280453
0.431144625126249
tq709098


50.7318874223712
-5.59642485933937
SW465987


52.0968934973257
-0.358719120254802
tl123456


52.0968934973257
-0.358719120254802
51232456


52.0968934973257
-0.358719120254802
512300245600



[note that the last three values in the query were all for the same grid reference but in different formats, producing the same lat/long]
For me this is pretty useful. I may well extend this to take more parameters and pass out KML, but the main thing is having a means to convert the data on the fly over HTTP.

Many thanks to Hairy Spider for doing all the hard work on this. I've tested the outputs and they're very close to the OS's own tool, so good work HS!

Next thing is to use this. I'll let you know when I do, and we might also be open about making the service publicly available if that would be of assistance to anyone that might be reading this.

AdaptiveBlue offers AB Meta. Did the earth move for you?

AdaptiveBlue is an interesting company. Although I've not found myself using their Blue Organiser tool all that much myself, I can see which way they're pointing and I like it. Now they have announced how they wish to refresh of the old familiar META tags in the heads of web pages with their take on object-centric metadata. AB Meta (apparently developed with other web companies) is all about surfacing semantic data into the layer that we typically interact with, and that even non-tech people can hopefully author without too much trouble. From their page:

AB Meta is a simple and open format for annotating pages that are about things.

A book publisher can use AB Meta to provide information about a book such as the author and ISBN, a restaurant owner can provide information such as the cuisine, phone number and address and a movie reviewer can annotate reviews with movie titles and directors.

The format allows site owners to describe the main thing on the HTML page in a very simple way - using standard META headers. AB Meta is purposefully simple and understandable by anyone. AB Meta is based on eRDF Standard.


I'm especially interested in this "surface" expression/implementation of SW. It's clear to me that much of the running in recent times has been made by companies looking to SW-style concepts and aspirations to deliver real benefits to their business, and only in a few cases has this led to them taking a classic-ish SW path (c.f. Reuters with OpenCalais). AdaptiveBlue and many others have instead set out along the light-weight, near-the-surface route, and as an eternal optimist (for some reason), I am hopeful that this will ultimately deliver the meat that the heavy-weight, deep SW needs to do something exciting. Thus killing the chicken/egg situation, with pay-offs along the way. This was the real take-home for me of last year's SW think tank.

Whether AB Meta has a part in this for museums I can't say. It's certainly lightweight but whether it will be different enough from existing alternatives to persuade our sector to adopt it, I don't know. Perhaps the earth will yet move.

As a PS, I should add that I dropped them a line to ask about a detail (whether it would be possible to include more than one object in the head of a page) and the reply came from CEO Alex Iskold. I think that's pretty impressive: presumably he's a busy guy (and he writes a good blog post, too) and yet he took the time to reply to a pretty pedestrian inquiry.

That IE7 prompt issue...

So here's why: Working around IE7s prompt bug, er feature (includes a possible solution)
Damn their eyes!

EDIT:
There's an alternative, but similar, solution here: http://www.anyexample.com/webdev/javascript/ie7_javascript_prompt()_alternative.xml. Both solutions require a relatively extensive script and callback, so it may be best if I stick it all into an external JS file and embed and call this with the bookmarklet. However I also now know that it's a security setting, so I've fixed my own IE installation. If you want to do the same, you must enable "Allow websites to prompt for information using scripted windows". Seems to all work then.

Bookmarklet update

OK, there are problems with with prompting bookmarklet in IE. It's all to do with the prompt. Yesterday it worked, but only on the first use, then it would stop prompting for the language-pair value (and in fact ignore the default value I'd put in there) and just skip straight to the translation page, which, without a language pair, can't do much. I think it may be to do with security, since it occasionally shows that "website trying to show active content" warning for a moment before scooting straight off to Google without a by-your-leave, let alone that prompt.

So for IE, for now, I'm just using a straightforward Italian-English bookmarklet
For Mozilla, the prompting version is now also Google-based and goes there. Here it is: translate
