For the benefit of the uneducated among us, would you care to explain this a bit more fully? To the extent that RDF Core truly introduces new concepts, it certainly should label them using an RDF namespace. However, if RDF wants to use values that have genuine XML datatypes (especially if those values are going to be represented in RDF's XML syntax), why should we not say "xsd:integer" rather than "rdfdt:integer"? I'm not talking now about datatypes that are "sort of like" XML datatypes, but are really and truly XML datatypes (as is, I believe, what we're trying to do). What's the point of having URIs if you have to invent new ones in order to refer to what is supposed to be the same concept from a different language? Talk about a "chaos of namespaces and architectures"! --Frank Sergey Melnik wrote: > > Janathan, Uche, DanC, > > thank you for identifying the problem (I do remember DanC's posting > related to grazing on someone else's grass ;) > > I'm going to replace xsd: by rdfdt: in the next revision of the > document. snip > > Uche Ogbuji wrote: > > > > > http://lists.w3.org/Archives/Public/www-archive/2002Jan/att-0131/01-RDF_Data > > > > typing.htm > > > > > > I am concerned that this document element names into the XML Schema > > > namespace.
