[RePost] XML Server

[Olivier Deckmyn <od...@teaser.fr>]

Hi all,

I have a need for an "XML Server" and I wonder if cocoon can fulfill my
needs :

What I want to do is a knowledge base (that might be huge), that is queried
and updated through the web.
The web site is made with zope (www.zope.org) an object oriented application
server.
I want to store my knowledge base in an XML DB.
When a user queries the KB (knowledge base), zope send a XPath or XQL query
to the XMLDB, via a simple HTTP Post for example. The result is sent via a
simple HTTP result : it should be the XML text of the answer.
I also need a way to update the XML data through HTTP (from the zope server
to the XMLDB)...but I don't know any query language for this...

Update performance can be medium...but it would be nice to have good query
performance.

I think that XSL services are useless for me, as the HTML formatting is done
on the Zope Server.

I know eXcelon can fullfill my needs but it is too expensive ($50K !!!) and
closed source...

Can I use cocoon to do so ? If yes, where can I find a simple sample that
will help me start ?
Or is ozone better for this job ?

please help !

thx .
