The California Digital Library's SearchLight service (
searchlight.cdlib.org/cgi-bin/searchlight), which was originally based upon the DBA code, has replaced DBA at the University of California, San Diego. Since we are no longer maintaining the code, please join the DBA mailing list and share your patches and improvements with other interested parties directly. We will not be releasing any patches or new versions of DBA ourselves. We encourage you to take the code and use it as you see fit, under the terms of the GPL. If you or your institution would like to volunteer to be the official maintainer of the DBA code, please contact Christy Hightower."
as seen at freshmeat: "This release adds backwards-incompatible API modifications, the ability to write to databases, an API for writing to databases, a QuickStart tutorial, Doxygen use for automatic documentation, prototype distributed searching, and multiple bug fixes. There are now no test suite failures." Visit open.muscat.com for more.
Both the Ecila (French) search engine codebase, catalog-1.0, and the U.K. eLib endproduct ROADS v2+ are open source and increasingly used tools for building web-based catalogs a la Yahoo. Some eLib folks have explicitly turned to open source as a way to keep formerly well-funded projects going (see the press release describing this decision). Open source as "exit strategy" isn't terrifically sustainable, but a step in the right direction nonetheless.
