Re: "Two-way Search" demo anyone?

Side note: I just put a recipe on-line that shows how the very same 
GoodRelations elements used for describing offers can be used for 
describing demand with the gr:seeks property.

http://tr.im/grseeks

BTW, you can combine that with most other recipes from

http://tr.im/cookbook

For instance, you could attach an image of a car wreck using 
foaf:depiction and ask for offers to repair (or to dispose ;-) ) that car.
