The gnuprologjava package by Constantine Plotnikov is an implementation of ISO Prolog as a Java library (gnu.prolog). We are looking for a new maintainer (Constantine is willing to answer questions and provide suggestions, but has no time to support it).

The first thing to do is ensure that the package works with GNU Classpath and/or the now-freed parts of openjdk, not just the proprietary JDK release from Sun. Other ideas from Constantine:

• It should really compile to JVM bytecodes to fasten things up and the compiled code should be more optimal with respect to unification and head matching.
• It should support part 2 of the ISO standard (modules).
• More documentation is required.
• The parser should be redesigned.

If you're interested, please take a look at this general information about GNU packages and being a GNU maintainer, and then email maintainers@gnu.org with a bit about your background and interest. Thanks!
