Hi Sherman:<br>
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).<br>
<br>
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:<br>
<br>
foo refers to the namespace of the example<br>
pcs refers to the namespace of a fictuous ontology for product types
and features (e.g. eclassOWL or others)<br>
<br>
foo:martinhepp <br>
a gr:BusinessEntity;<br>
gr:offers foo:myWant1.<br>
<br>
foo:myWant1<br>
a gr:Offering ;<br>
gr:hasBusinessFunction gr:Buy;<br>
gr:hasPriceSpecification foo:UnitPriceSpecification_1 ;<br>
gr:includesObject foo:TypeAndQuantityNode_1 .<br>
<br>
foo:myDreamTVSet<br>
a pcs:TVSet , gr:ProductOrServiceSomeInstancesPlaceholder;<br>
pcs:hasScreenSize foo:QuantitativeValueFloat_1.<br>
<br>
foo:QuantitativeValueFloat_1<br>
a gr:QuantitativeValueFloat ;<br>
gr:hasUnitOfMeasurement "CMT"^^xsd:string ;<br>
gr:hasMinValueFloat "30.0"^^xsd:float .<br>
<br>
foo:TypeAndQuantityNode_1<br>
a gr:TypeAndQuantityNode ;<br>
gr:amountOfThisGood "1.0"^^xsd:float ;<br>
gr:hasUnitOfMeasurement "C62"@en ;<br>
gr:typeOfGood foo:myDreamTVSet .<br>
<br>
foo:UnitPriceSpecification_1<br>
a gr:UnitPriceSpecification ;<br>
gr:hasCurrency "EUR"^^xsd:string ;<br>
gr:hasMaxCurrencyValue "200.0"^^xsd:float ;<br>
gr:hasUnitOfMeasurement "C62"^^xsd:string .<br>
<br>
<br>
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.<br>
<br>
<br>
That would be a minimal change to the vocabulary but would allow to
reverse all BusinessFunctions (e.g. seeks maintance, seeks disposal,
etc."<br>
<br>
What do you think?</div></blockquote><div><br>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). <br>
<br>As for negotiations, we could make the object of the <span style="font-family: courier new,monospace;">gr:offers</span>/<span style="font-family: courier new,monospace;">gr:seeks</span> property the <span style="font-family: courier new,monospace;">sioc:topic</span> of a <span style="font-family: courier new,monospace;">sioc:Post</span> to link to the natural language discussion. To link the structured reply offers and counter-offers, we could use <span style="font-family: courier new,monospace;">sioc:replyTo</span>, i.e.<br>
<br><span style="font-family: courier new,monospace;">foo:Negotiation1</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;"> a sioc:Post</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;"> sioc:topic foo:theirOffer1</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;"> 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</span><br style="font-family: courier new,monospace;">
<br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">...</span><br style="font-family: courier new,monospace;"><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">foo:theirOffer1</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;">
a gr:Offering ;</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;"> sioc:replyTo foo:myWant1</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">
gr:hasBusinessFunction gr:Sell;</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">
gr:hasPriceSpecification foo:UnitPriceSpecification_2 ;</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">
gr:includesObject foo:TypeAndQuantityNode_1 .</span><br style="font-family: courier new,monospace;">
<br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">foo:betterOffer1</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">
a gr:Offering ;</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">
sioc:replyTo foo:theirOffer1</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">
gr:hasBusinessFunction gr:Sell;</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">
gr:hasPriceSpecification foo:LowerUnitPriceSpecification_3 ;</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">
gr:includesObject foo:TypeAndQuantityNode_1 .</span><br>
<br><br>Does that make sense? Using <span style="font-family: courier new,monospace;">sioc:replyTo</span> would cover negotiations, while enabling eBay-style auctions as well as reverse auctions.<br><br>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.<br>

<pre>Hi All,
I've considering the GoodRelations ontology for <a href="http://overdogg.com" target="_blank">overdogg.com</a> wants and
needs. Looking at the GR spec [1], I am not able to see anything classes or
properties for describing wants/needs. I created the Things You Want and
Need (TIWAN) ontology[2] to model wants/needs as well as reverse
auction-style marketplace. I would like to know if a merge between the two
would be something that you would be interested in. I can definitely see
where GR plugs into TIWAN, e.g. to describe providers/suppliers. Is
wants/needs within the scope of GR, or should I continue using TIWAN with
tie-ins to GR?
