Gathery and Giftag

So here, by the sound of it, is the hProduct equivalent of Gathery, the application I built to collect museum objects marked up with some POSH. No-one was going to support an object microformat, for strong reasons (though I still wish there was a more general object uF for objects than hProduct), but essentially this product is the same thing, but for making a wish-list. Read more on RWW: Giftag: Social Wishlists Using Open Standards . I'm wondering now, though, whether there might be mileage in using hProduct with extensions for museum collections - it's still better than the nothing we have at present.
