Eric van der Vlist has developed a Java interface for R.V. Guha's rdfDB, a lightweight RDF database.

Describing the new interface, van der Vlist writes:

This new interface allows querying the database using its query language and to get the results back row by row and column by column in plain Java and/or as a result tree fragment in a XT XSLT transformation.

Van der Vlist has pressed his new interface into action on his XMLfr site, using the RDF database in conjunction with an XSLT style sheet to automatically generate per-topic pages. (An example for "Java".)
