However, RDDL works reasonably well as as long as namespace URI == URL That is, you can put a RDDL document at a ftp or even a mailto URL if you care to. The problems only arise when namespace URI == URN. This may come down to first answering the question of how one resolves URNs. Then we can put RDDL documents there too. :-) >What is good about RDDL is that it solves "some" of the problem which is how >to get markup/create/present metadata about a namespace.

Of course, this requires first solving the problem of how to resolve URIs that aren't URLs. -- +-----------------------+------------------------+-------------------+ | Elliotte Rusty Harold | elharo@m... | Writer/Programmer | +-----------------------+------------------------+-------------------+ | The XML Bible, 2nd Edition (Hungry Minds, 2001) | | http://www.ibiblio.org/xml/books/bible2/ | | http://www.amazon.com/exec/obidos/ISBN=0764547607/cafeaulaitA/ | +----------------------------------+---------------------------------+ | Read Cafe au Lait for Java News: http://www.cafeaulait.org/ | | Read Cafe con Leche for XML News: http://www.ibiblio.org/xml/ | +----------------------------------+---------------------------------+
