Apache Jackrabbit is an open source content repository for the Java platform. The Jackrabbit project was started on August 28, 2004, when Day Software licensed an initial implementation of the Java Content Repository API (JCR). Jackrabbit was also used as the reference implementation of JSR-170, specified within the Java Community Process. The project graduated from the Apache Incubator on March 15, 2006, and is now a Top Level Project of the Apache Software Foundation.

JCR specifies an API for application developers (and application frameworks) to use for interaction with modern content repositories that provide content services such as searching, versioning, transactions, etc.
