Java Content Repository (JCR) Standard

The JCR standard, specified in the Java Specification Request 170 and 283, is an implementation independent way to access content bi-directionally on a granular level within a content repository. The JCR standard allows for the clear separation of reusable repository functionality (search, versioning, access control, etc.) from application-specific functionality.

This allows the developer to concentrate on applications' core features, considerably shortening development time. Different applications can use the same API to access content, so that development and maintenance becomes more efficient, improving the total cost of ownership of content applications.

Roy T. Fielding, Ph.D., Chief Scientist

The Content Repository API for Java Technology (JCR) is poised to revolutionize the development of Java EE applications in the same way that the Web has revolutionized the development of network-based applications. JCR ’s interface designers have followed the guiding principles of the Web to simplify the interactions between an application and its content repository, thus replacing many application-speciﬁc or storage-speciﬁc interfaces with a single, generic API for content repository manipulation.
