		<description>Your post set prompted me to look into several solutions.  I ended up surveying the bulk of the xml database field.  The end result that I wanted to pass by you, is, why not use IBM&#039;s DB2 Express-C 9.5 (a free edition, a mature platform on various OSs) and transition the Daisy repository to a pure xml db?  DB2 would allow a transition path from the relational model, using the current Daisy relational db schema, to a pure xml-based repository solution, in the same database. 

See page 55, Fig 2.2 of &quot;http://www.redbooks.ibm.com/abstracts/sg247301.html?Open&quot; for where I&#039;m coming from, along with the surrounding explanation.

The end solution would allow managing entities with a flexible set of attributes (Daisy documents) using a non-relational, XML databaase with Daisy Query mapped to XQuery with its performance attributes.

This has been fun.  Daisy is great!</description>

		<description>Thanks for the links.

BTW, currently these are just some random musings, no actions planned.</description>

		<description>Given Daisy&#039;s document-centric approach, something like &lt;a href=&quot;http://www.couchdbwiki.com/index.php?title=Main_Page&quot; rel=&quot;nofollow&quot;&gt;CouchDB&lt;/a&gt; might also be appropriate.  Although it&#039;s probably not quite ready for &quot;prime time&quot; yet, it might be worthwhile to continue watching this space.

I&#039;m &lt;em&gt;very&lt;/em&gt; interested to see where you go with this.</description>

		<description>Interesting topic! I&#039;ve often thought about Daisy&#039;s storage model in this context too. You may also be interested in the column store work at the Hadoop project, which includes an RDF api through Hbase.

This recent write up on Amazon&#039;s Dynamo project may be of interest too: http://allthingsdistributed.com/2007/10/amazons_dynamo.html</description>
