What do you think?

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.
foo:Negotiation1
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
...
foo:theirOffer1
a gr:Offering ;
sioc:replyTo foo:myWant1
gr:hasBusinessFunction gr:Sell;
gr:hasPriceSpecification foo:UnitPriceSpecification_2 ;
gr:includesObject foo:TypeAndQuantityNode_1 .
foo:betterOffer1
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.
