[Kent Fitch:] > Is RDF a candidate for representing Topic Map > type assertions about resources? This is a good question. Like you, I have a hunch that it's possible that it's possible. If we assume it's true that topic maps can be interchanged as RDF documents, it's also important to ask whether or under what circumstances it would be worth the effort to use RDF. I'd very much like to know good technical and/or economic arguments in favor of preferring an existing or proposed RDF-based syntax over the hyperlinks ("extended" xlinks) already being used to interchange topic maps. Does anyone know any such arguments? I attended Ora Lassila's excellent talk on RDF at XML 99, which made the RDF phenomenon a lot clearer for me. During the question period, I asked from the audience whether the RDF model would be supportable by using extended xlinks to express tuples and their arcs. Ora said that RDF is a set of abstract notions that exist at a higher level than specific syntaxes. He said that he would welcome an alternative syntax based on xlink. It's also interesting to note that one completely separable and optional part of the Topic Maps architecture, called "facet link", is an xlink whose semantic appears to be at least in some respects indistinguishable from the tuplet-and-arc semantic carried by RDF tuplets. If facet links can be used to express RDF-based assertions (and I don't yet know any reason why they can't), then there already is an xlink-based syntax for RDF, defined by the Topic Maps standard. -Steve -- Steven R.
