Description:

The Apache Jackrabbit™ content repository is a fully conforming implementation of the Content Repository for Java™ Technology API (JCR, specified in JSR 170 and 283). The Jackrabbit content repository is stable, largely feature complete and actively being maintained.

Jackrabbit Oak is an effort to implement a scalable and performant hierarchical content repository as a modern successor to the Apache Jackrabbit content repository. It is targeted for use as the foundation of modern world-class websites and other demanding content applications. In contrast to its predecessor, Oak does not implement all optional features from the JSR specifications, and it is not a reference implementation.

Project Activity:

Apache Jackrabbit Oak receives most attention nowadays. All maintenance branches and the main development branch are continuously seeing moderate to high activity.

Apache Jackrabbit itself is mostly in maintenance mode with most of the work going into bug fixing and tooling. New features are mainly driven by dependencies from Jackrabbit Oak.

The team is further reducing usage of Google's Guava library and Jackrabbit Oak is now using Java features where possible. The long term goal is to remove the dependency on Guava.

The Solr integration module has been removed from Jackrabbit Oak, after deprecating it last year. Instead, the team invested heavily into integration with Elasticsearch and added AI/ML inference capabilities.

Community Health:

The project is generally healthy with a continuous stream of traffic mostly on JIRA issues and GitHub pull requests reflecting activity of the respective component.

Commit activity is moderate, mirroring the activity on the JIRA issues and the desire of the individual contributors to bring features and improvements in for the next Jackrabbit Oak release.
