Universal Data Element Framework (UDEF)A
nice comment in today's Semantic Web discussion group pointing to an underlying problem: "If we want RDF-based formats to be interoperable, they can't be extensible, because inevitably some mutually incompatible extensions or vocabularies will arise, or they can't be decentralized since some authority will have to maintain this interoperability." The author, Adam Atlas (?), lays out three approaches: (1) hardcode these similarities in function into parsers, (2) create new ontologies for the express purpose of bridging these similar but incompatible formats, or (3) politely ask the vocabulary authors to add compatibility. None of these, he argues, is workable.
