An open-source, federated content repository

JSR-283 now at Proposed Final Draft

JSR-283 has just reached the proposed final draft stage, and the latest specification is now available for download. The reference implementation (RI) and technology compatibility kit (TCK) will be done as part of Apache Jackrabbit project.

David Nuescheler, one of the authors, has a nice summary of what’s new in JSR-283.
Update 1: I do have to say that I’m disappointed in the license for the draft. Unlike some other recent JSRs (e.g., JSR-303), the JSR-283 license (apparently) does not allow for implementation of the spec, even for testing or evaluation purposes.

    Thanks a lot for the comments around the JSR-283 licensing. It is definitely our intention to have the of JCR 2.0 as liberal as possible, which in my mind means to be as close as possible to the Apache License 2.0.During JSR-170 we were constrained by the JCP license requirements, so I really appreciate any suggestion that we could use to make the final license as liberal as possible, especially if there is precedence with.Please send any suggestions to

    Thanks for replying, David. The main thing I’d like to see is the ability to implement the spec (with common sense limitations), much like the JSR-170 license or the more recent JSR-303. Perhaps it’s already allowed by the JSR-283 license, but it’s not obvious if it is. Per you’re suggestion, I’ve just emailed the suggestion to the JSR-283 group.

ModeShape is

a lightweight, fast, pluggable, open-source JCR repository that federates and unifies content from multiple systems, including files systems, databases, data grids, other repositories, etc.

Use the JCR API to access the information you already have, or use it like a conventional JCR system (just with more ways to persist your content).

ModeShape used to be 'JBoss DNA'. It's the same project, same community, same license, and same software.
