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)

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

foo:myWant1
      a gr:Offering ;
      gr:hasBusinessFunction gr:Buy;
      gr:hasPriceSpecification foo:UnitPriceSpecification_1 ;
      gr:includesObject foo:TypeAndQuantityNode_1 .

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

foo:QuantitativeValueFloat_1
      a gr:QuantitativeValueFloat ;
      gr:hasUnitOfMeasurement "CMT"^^xsd:string ;
      gr:hasMinValueFloat "30.0"^^xsd:float .

foo:TypeAndQuantityNode_1
      a gr:TypeAndQuantityNode ;
      gr:amountOfThisGood "1.0"^^xsd:float ;
      gr:hasUnitOfMeasurement "C62"@en ;
      gr:typeOfGood foo:myDreamTVSet .

foo:UnitPriceSpecification_1
      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?

Best
Martin
