My thoughts on various sections: :::4. An interpretation of XML and namespaces::: This section doesn't seem to give an interpretation of namespaces especially after previous section leaves the reader hanging but instead seems to dwell on the philosphical question of what should be done about elements with no namespace URI.I think that entire section is an unecessary digression that disrupts the flow of the article. :::5. An interpretation of schemas::: I like the way this section describes the relationship (or lack thereof) between namespaces and schemas. :::8. A proposal for an answer to the riddle : the Namespace Description Language::: You state "What should I obtain when resolving a namespace name ? A Namespace Description Language document. This is NOT a collection of names, but a program can build a collection of names from it. Apart from the different names appearing in the namespace, what information could the NDL document provide ? Well, I'm not sure yet, but I think that for each name which corresponds to an element name, there should be the definition of the correponding element type URI. This URI would enable us to fetch a meta-data RD and get some associated resources, like a human-readable documentation of the general meaning (e.g. out of any pattern) of the tag." This reads like a reinvention of RDDL to me. The interesting problems that RDDL doesn't solve are (a.) Where to place RDDL files for XML documents containing elements from multiple namespaces such as MSFT's annotated XSD schemas for creating XML views of relational data that typically contain elements from 2 or 3 namespaces (as a practical example) and similarly (b.) Where to place RDDL files for namespaces that do not have a resolvable namespace URI. Your description of a NDL doesn't seem to address these problems. -- THINGS TO DO IF I BECOME AN EVIL OVERLORD #229 If I have several diabolical schemes to destroy the hero, I will set all of them in motion at once rather than wait for them to fail and launch them successively. ----- Original Message ----- From: "Nicolas Lehuen" <nicolas.lehuen@u...> To: "Jonathan Borden" <jborden@m...>; "Leigh Dodds" <ldodds@i...>; <xml-dev@l...>; "Joe English" <jenglish@f...> Sent: Saturday, January 19, 2002 9:13 AM Subject: Re: What a namespace is. > I've updated the article I wrote on my Web site : > > http://nicolas.lehuen.com/Articles/Programming/Ideas/fog0000000033.html > > It is not authoritative in anyway.
