Raj, re your second proposal, can you clarify the difference between
Thing/link, the existing Thing/url, and the object's id (microdata @itemid,
RDFa @about)? Would Thing/link serve the same purpose as the proposed
sameThingAs property <http://www.w3.org/wiki/WebSchemas/ThingIdentity>?

Thanks,
Justin
