[DDI-users] Storing XML

[Mark R. Diggory]

Hi Andrew,

This is a shameless plug for a system we have been developing.

We are working on an Opensource Digital Library System that utilizes the 
DDI are its primary storage XML format. This system is primarily for 
Social Science Reseach data such as that published at the ICPSR. It 
provides Indexing/Searching capabilities and server side data analysis 
tools for subsetting and manipulating the datasets. We are preparing for 
a software release towards the end of this year.

Feel free to find out more about this project at the following sites:

http://www.hmdc.harvard.edu
http://www.thedata.org
http://thedata.sourceforge.net

We have a couple production systems running at Harvard. This is an older 
version of the "Virtual Data Center". But will be upgraded to our 
release version once it is completed.

p.s. We currently archive the DDI's in a custom repository backed by 
Postgresql. I have been researching eXist http://exist.sourceforge.net 
or Xindice as a possible future Repository Implementations and have some 
rudimentary Tests/Implementations in the works.

At this stage of development we are investigating the possibilities of using some sort of XML-aware database management system. Currently, I am considering Xindice system (formerly dbXML) developed by Apache Software Foundation as a possible tool for our needs. However, I would very much like to know how other developers address the similar problem. What tools, database management systems and languages do they use?
