Namespace Definitions: Cracks!
I said that the most important problem of using namespaces as SW architecture is that they aren't definitive. TimBL noted that "a langauge definition = a namespace", and that there are "problems in defining langauges":- [[[ (There is currently (1999/9) much debate in the XML world over exactly what defines a language, the proposed answers ranging though: the publisher of the namespace including any information in the definitive schema; a separate note of a schema; a schema plus a different namsepcae URI document plus a version plus an HTML profile; and "nothing". If this debate resolves itself such that athe identity of a language is not clearly defined. In that case the XML namespace mechanism may prove an insufficiently firm foundation for the semantic web, or any application of data on the web.) ]]] - http://www.w3.org/DesignIssues/Meaning.html I don't like to say "I told you so" but (there's no way I can finish this sentence); read on:- O.K., so how do we define a langauge, and therefore namespace? I argued that we dereference it and look for a schema who's namespace eventually points to a self-describing Schema (such as XML Schema), but I'm beginning to think that the foundations of Web architecture are a quagmire of doubt and uncertainty. Now it's everyone elses turn to say "I told you so" at me... Kindest Regards, Sean B.
