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.

[goodrelations] GoodRelations and TIWAN ontology

Hi Sherman:
Thanks - Briefly: I think we should integrate the efforts. Basically, it 
is simple to model wants and needs in GoodRelations. You just use a 
gr:Offering with the gr:BusinessFunction gr:Sell - this goes with the 
batteries supplied in the current version of GoodRelations (even though 
I never thought of this application before).

Example: I am interested in buying one TV set with a screen size of at 
least 30 centimeters, and i am not interested in offers more expensive 
than 200 euros:

foo refers to the namespace of the example
pcs refers to the namespace of a fictuous ontology for product types and 
features (e.g. eclassOWL or others)

    a gr:BusinessEntity;
    gr:offers foo:myWant1.

      a gr:Offering ;
      gr:hasBusinessFunction gr:Buy;
      gr:hasPriceSpecification foo:UnitPriceSpecification_1 ;
      gr:includesObject foo:TypeAndQuantityNode_1 .

      a pcs:TVSet , gr:ProductOrServiceSomeInstancesPlaceholder;
      pcs:hasScreenSize foo:QuantitativeValueFloat_1.

      a gr:QuantitativeValueFloat ;
      gr:hasUnitOfMeasurement "CMT"^^xsd:string ;
      gr:hasMinValueFloat "30.0"^^xsd:float .

      a gr:TypeAndQuantityNode ;
      gr:amountOfThisGood "1.0"^^xsd:float ;
      gr:hasUnitOfMeasurement "C62"@en ;
      gr:typeOfGood foo:myDreamTVSet .

      a gr:UnitPriceSpecification ;
      gr:hasCurrency "EUR"^^xsd:string ;
      gr:hasMaxCurrencyValue "200.0"^^xsd:float ;
      gr:hasUnitOfMeasurement "C62"^^xsd:string .

In order to make this a bit more beautiful an powerful, I could 
introduce a new objectproperty "seeks" that is used instead of "offers" 
to link between a business entity and an offering.

That would be a minimal change to the vocabulary but would allow to 
reverse all BusinessFunctions (e.g. seeks maintance, seeks disposal, etc."

What do you think?
