Today sees the release of the latest version of TM4J, the open-source topic map engine. This release is primarily a bug-fix release, but also enhances the tolog query implementation to enable dynamic association predicates to use a variable for the association type, thus allowing queries such as: $ASSOC(foo, bar) to find the type of all associations between topics foo and bar.

Source and binary distributions can be downloaded from the TM4J SourceForge page.
