GoodRelations - The Web Vocabulary for E-Commerce

This is the archive of the goodrelations dicussion list

GoodRelations is a standardized vocabulary for product, price, and company data that can (1) be embedded into existing static and dynamic Web pages and that (2) can be processed by other computers. This increases the visibility of your products and services in the latest generation of search engines, recommender systems, and other novel applications.

The gr:seeks property is brilliant! This will allow GR to encompass a
"buyer's market" in one fell swoop. I've gone through TIWAN and the only
thing unaccounted for would be discussions/negotiations and service oriented
requests (or offers to buy).

As for negotiations, we could make the object of the
gr:offers/gr:seeksproperty the
sioc:topic of a sioc:Post to link to the natural language discussion. To
link the structured reply offers and counter-offers, we could use
sioc:replyTo, i.e.

        a sioc:Post
        sioc:topic foo:theirOffer1
        sioc:content "I can get you that after I get off work tonight, I
live around the block from you and have this set in my garage, great cond.,
just give me a call"^^xsd:String


      a gr:Offering ;
      sioc:replyTo foo:myWant1
      gr:hasBusinessFunction gr:Sell;
      gr:hasPriceSpecification foo:UnitPriceSpecification_2 ;
      gr:includesObject foo:TypeAndQuantityNode_1 .

      a gr:Offering ;
      sioc:replyTo foo:theirOffer1
      gr:hasBusinessFunction gr:Sell;
      gr:hasPriceSpecification foo:LowerUnitPriceSpecification_3 ;
      gr:includesObject foo:TypeAndQuantityNode_1 .

Does that make sense? Using sioc:replyTo would cover negotiations, while
enabling eBay-style auctions as well as reverse auctions.

I'm pleased to see that Services are indeed covered by GR. Other than the
above example, I see no need to continue development of TIWAN.
