Jackrabbit is the open-source implementation of JSR 170, the Java Content Repository (JCR) API. JCR aims provide a standard Java-based API to content management systems, offering these features:
Granular read/write access, allowing fine-grained access to content elements.
Versioning across the entire content repository, and of any content within the repository, with the ability to select any version of any repository item.
Event monitoring (observation) provides a subscription mechanism on content modification.
Full-text search and filtering, with the ability to index the contents of the entire (non-binary) content of the repository. Jackrabbit currently integrates out of the box with Lucene.
Fine-grained access controls with JAAS or ACLs.
Object classes allow profiles or document types to be defined and inherited, with constraints specific to a content type. This gives the application programmer the ability to operate on content object types.
Namespaces and standard repository properties are defined to allow namespace uniqueness and hierarchy for the stored content.
Locking and concurrency facilitates concurrent access to repository content.
Linking between content elements provides a standard mechanism to enforce soft and hard link in the data model.
After a long development period, the Jackrabbit project made its 1.0 release. It can be downloaded from the following URL: http://jackrabbit.apache.org.
