Is there any interest on the list in storing biological/genetic information in XML databases? I'm developing an open-source embeddable native XML database and I'm getting quite a lot of interest from people working on biotech projects. I thought this would be a good place to announce its availability. Release 1.0.10 includes APIs for Java, C++, Python, Perl, Ruby and Tcl. This is a bit of an essay question... but I'd be interested to hear about any specific requirements this community has for database systems. Are relational stores perfectly suited to your kind of work? John Berkeley DB XML: http://www.sleepycat.com/products/xml.shtml
