That was one of the threads (Distributed RDDL) I started reading before I noticed the January date... This time I went and read (most of) Keith Moore's RESCAP draft and immediately I thought of the last great NS URI dereferencing war. At the time I said something like, "if you had a DNS-like substance for URIs, you could look before you leap." Have a look at http://www.ietf.org/internet-drafts/draft-moore-rescap-rc-00.txt A RESCAP recursive query would help RDDL processing (the client could pass the NS URI back and receive all the URIs contained in the document). It seems a bit tricky to capture both arcrole and role in the results (simple attribute name/value pairs). RESCAP could work fine for simple NS URI aliasing, however. I.e. you could use a good, long term URN-type NS URI and provide a list of mirrored, load-balanced and/or locally cached instances of the schema document available over either HTTP or FTP. Because it supports signed data, a local server could maintain a secure cache. take it easy, Charles Reitzel At 01:04 PM 3/12/01 -0500, you wrote: >At 03:43 PM 3/12/01 +0100, Eric van der Vlist wrote: >>The URI may be a good schema location for my processing needs and a bad >>choice as a base name for my datatypes. >> >>The prefix is a shorthand for the namespace URI that is, in principle, >>independent of the schema location. >> >>This is a powerful feature of W3C XML Schema that would be lost if the >>namespace URI had to match the schema location. > >I'm starting to wonder if maybe we need options which combine the >capabilities of RDDL with the indirection of technologies the IETF is >developing for asking questions about the nature of particular URIs. > >URI metadata might dig us out of this problem.
