Hi, devs. Thanks for feedback.
There are important info from JCR v2 [1] unfinished standard (Public Review. Final release at Sep-2008): http://wiki.apache.org/jackrabbit/Proposed_JCR_2%2e0_API_Changes - xpath & jcrsql are deprecated in jcr2, but supported + new language JCR-SQL2 which is much extended jcrsql with joins. + new Java API for quering called QueryObjectModel (JCR-JQOM) (like Hibernate Criteria or LINQ) recent Jackrabbit 1.4 already has this features, but they are not stable yet. eXoJCR hasn't this features yet. Jackrabbit has a parser [2] from JCR-SQL2 to JCR-JQOM, so we can simply translate some subset of QOM to HQL. What else parsers / query frameworks can you recommend? I looked at some jpa, jdo ql implementations but they are not expose nice Query Model for reuse.
