Hibernate Query Parser
Experimental new parser for HQL and JPA-QL queries, to convert these into SQL and other different targets such as Lucene queries, Map/Reduce queries for NoSQL stores, make it possible to perform more sophisticated SQL transformations.
There is much to do and many tests to be ported from the existing parser or added from scratch; anyone is welcome to help by sending pull requests, commenting the code on github directly or by by using the mailing list or IRC chat channels:
