ContentBasedQuery questions/ideas.

[Matthew MacKenzie <matt@xmlglobal.com>]

Team,

I have started looking more closely at ContentBasedQuery, and have a few 
questions for those of you that may have been more closely involved with the 
registry specifications.  Please excuse my ignorance if I am off in left 
field, here are my observations and questions:

1.  Does ContentBasedQuery need to fall under the FilterQuery umbrella? (I 
think not, just checking.)

2.  In the RS spec, appendix D talks about a syntax for defining 
"Classification Indexes".  I read this over and over and don't really see how 
these details relate to content based queries, they seem to relate more to 
defining how a registry implementer might  build side tables in their RDBMS 
so that a keyed query could take place (e.g. id-1 LIKE fo% AND id-2 LIKE 
%ar).  Does the ContentBasedQuery spec have to address the needs of the SQL 
implementer, or should it remain technology neutral with apendixes for 
implementation specific issues (if available)?

3.  How does everyone feel about a "Content Handler" architecture that would 
allow for a content based query to span more than just XML documents?  The 
registry's self describing CPP could contain a list of mime types that can be 
content searched, and the implementation of each content type other than 
XML/HTML and plain text could be left up to registry vendors.

Thoughts? Opinions? Flames?

Also, if you would like to volunteer to help with this stuff, let me know.
