I see a difference between the identification role of sameThingAs and Raj's proposal for a property that can be used to categorize something. This is based on my assumption that a category for the church named "Sagrada Familia" might be a link to the wikipedia category "Churches in Barcelona" or the geonames code "CH" for "church." If sameThingAs also exists as a property, then the link to dbpedia:Sagrada_familia would use that property. I wouldn't expect to see sameThingAs -> geonames:CH. Raj, have I understood your meaning of "category"? kc > > I don't think Thing/url could be made to work for this purpose.
