Jackrabbit 3

Project Oak (formerly Jackrabbit 3) is an effort for a new implementation of the JCR specification. In contrast to Jackrabbit 2 the goal is not to implement all optional features of the specification but rather to distil out the most important ones and trade the rest for a more lightweight and performant implementation. Currently this page is merely a collections of links. It should however evolve into a more elaborate source of information once the project progresses.

Technical

• OakErrorCodes

• Conflict handling through rebasing branches

• Some early information is available from the RoadMap (mostly out of date). Here is a more up to date release road map.

• Oak-over-HTTP

• Jackrabbit 3 Strategic Plan

• Goals and non goals for Jackrabbit 3

• OakComponentStructure

• Jackrabbit 3 will be based on a small Microkernel on top of which most of the JCR functionality will be implemented.

• The Microkernel uses a flavour of the Jsop protocol for its API.

• Transactional model of the Microkernel based Jackrabbit prototype

• Index Implementations

• Clustering the Microkernel

• Slides: Implementing JCR on the Microkernel

• Recent technical discussions on the dev list:

  • jr3 http api as a first class citizen

  • jr3 trade consistency for availability

  • jr3 On pluggability and OSGi

  • jr3 clustering and Apache ZooKeeper

  • jr3 optional features

• Support usage of JAAS based authentication with Repository in OSGi
