JSR 170 ou Content Repository for Java (JCR)

JSR 170 or Content Repository for Java (JCR) is a specification defining a set of APIs and interfaces allowing access to the repository Java regardless of the operating system where information is stored. It allows the various solutions and ECM to gain access to a set of directories content distributed on a heterogeneous network, for example.

This specification was developed under the Java Community Process and was accepted in its final version on June 17, 2005. The reference implementation is the project Apache Jackrabbit (http://jackrabbit.apache.org/) in its version 1.0 in April 2006. Currently the latest version is the jackrabbit-core 1.4.5 released on 9 June 2008.
The future of the JSR-170 is the JSR-283. Currently it's a draft version.

The idea behind JSR 170 is to facilitate extraction and publication of information with a Web browser. It's also communication between repositories. Indeed, the contents can be indexed in different benchmarks but remain accessible without specific developments.
