Re: ProductDB
Awesome indeed, but the two solutions are not equivalent, because
owl:propertyChainAxiom is a regular implication (a sufficient
condition to conclude barter:wants, but not its inverse), while your
N3 looks like you want an equivalence axiom (both the sufficient
condition and its inverse).

I really need to take a closer look at OWL2. Without knowing
about owl:propertyChainAxiom, I would have suggested N3:
{
?person gr:seeks ?off .
?off gr:includesObject ?obj .
?obj gr:typeOfGood ?product .

All wiki content is licensed under the GFDL. This first conversion contains product names, list prices, alternate names, reviews and links to external sites for over 20,000 products represented using a blend of GoodRelations, FOAF and OpenVocab. The product categorisation scheme has been converted using SKOS. There are about 500,000 triples in the dataset and since it is Linked Data, all the entities have URIs. For example: * http://productdb.org/apple-iphone * http://productdb.org/2006-porsche-boxster There are some owl:sameAs links to dbpedia resources, e.g. * http://productdb.org/asus-eee-pc-701 * http://productdb.org/shaun-of-the-dead We hope to improve cross-linkage to other datasets in the future. Talis provides a SPARQL end-point at: http://api.talis.com/stores/productdb/services/sparql Other services such as free-text search and faceting are linked from: http://api.talis.com/stores/productdb Cheers, Ian Ian, Awesome!

Aha. I'm not surprised that GoodRelations provides such a relation - it's fairly comprehensive. I'm be a little concerned over it's complexity for common FOAF-like use cases though. There's quite a lot of indirection to get from the foaf:Person to the product they want - in GoodRelations, a person would seek an Offering, which includes a TypeAndQuantityNode which has a type of good which is the end product. So: #me gr:seeks [ gr:includesObject [ gr:typeOfGood #product ] ] . Really I'd just want something like: #me ex:seeks #product . Yes, that's not quite as expressive - I can't say how much I'd be willing to pay for it, or how many I want, or in what timeframe I want to buy it, but it's enough for a simple wishlist. ex:seeks could of course be defined in terms of gr:seeks, so that mapping could be done in both directions, but I do think that a simpler term is needed. Then a wishlist becomes as easy as: a sioctypes:WishList ; foaf:maker #me . #me ex:seeks #product1 , #product2 , #product3 . Ian's barter vocab is closer to this, though I think it could be improved by specifying domains and ranges for the terms and generally defining them a little less loosely. -- Toby A Inkster mailto:m...@tobyinkster.co.uk http://tobyinkster.co.uk
