Rafael,

I would love to review the adapter and commit that to the project, and I
would add my own Derby adapter.

Subject: Slide DB2 pureXML Adapter

Hi Folks,

Happy New Year!

I have been working with Zeus to develop a DB2 v9 pureXML Adapter.  And we
would like to contribute it back.

What does it do?
1) Simplifies the relational schema
This adapter stores the Slide metadata using the file adapter XML file
schema/format.  But it uses a lot of the Relational Adapter classes.  You
can think of it as a relational adapter that is aware of the new XML type.
This greatly simplifies the relational schema.  The prototype implementation
currently has only two tables each with 4 columns.

2) Stores XML in an XML column
The other thing this database adapter does is it stores all XML data in an
XML column and all non-XML in the BLOB column.  This will allow folks who
store XML the ability to query the XML using parametric XQueries to search
and manipulate documents.

We have been running it against the Slide test suite and it seems to pass as
well as the other relational adapters.

Would a slide contributor be interested in reviewing the code?  What do you
think?

regards,
