JCR Mangement (JCRM)
JCR Management will provide tooling and a JCR (http://en.wikipedia.org/wiki/Content_repository_API_for_Java) persistence framework for EMF with pluggable JCR implementations.
The Contributions
- My employer inovex GmbH (http://www.inovex.de) contributes 7 person days where I can work on this project within working hours.
- Ed Merks:
- helps as a mentor for questions regarding the Eclipse foundation.
- implemented a new feature request for EMF that I had (dynamic feature delegation)
- answers a lot of my questions in the newsgroup
- The ATL team contributed an initial meta model and transformation that will speed up ATL integration.
- Nick Boldt created the initial JCR Management (CVS, website, ...) setup at eclipse.org
Tasks
- See Bugzilla for an overview of the ToDo's https://bugs.eclipse.org/bugs/buglist.cgi?short_desc_type=allwordssubstr&short_desc=&product=EMFT&component=JCR+Management&long_desc_type=allwordssubstr&long_desc=&order=Importance
Status
Development of a demoable prototype finished.
Next Milestone
Create a first downloadable presentation of the project to show the potential of Eclipse modeling to the Jackrabbit community.
Ideas
- Using Cedrics Compare editor inside the JCR Manager
Values
- simplicity
- transparency
- no dependency on JCR implementations
FAQ
- What's the relationship between JCR Management and Jackrabbit JCR-OCM?
One part of JCR Management has the same goal as JCR-OCM - exposing node data and operations to domain models - but it uses an MDSD approach based on Eclipse Modeling Framework (EMF). This makes JCRM depending less on reflection and using more generated classes instead. It will delegate as many calls on JCR node data as possible to minimize copying node data to domain model objects. Additionally JCR Management also has many other goals. The source code of JCR-OCM can be found at http://svn.apache.org/viewvc/jackrabbit/trunk/contrib/jackrabbit-jcr-mapping/jcr-mapping/ and the documentation is in the former Graffito project (http://incubator.apache.org/graffito/jcr-mapping/index.html).
CVS Access
Some important things are now checked in. Third party jars are not yet checked in as the IP for Jackrabbit needs to be reviewed by Eclipse. Please use the plugin id's as project names ("org.eclipse.emf.jcrm.metamodel" and "org.eclipse.emf.jcrm.model")
CVS Repository Connection
- Server: dev.eclipse.org
- Repository Path: /cvsroot/modeling
- User: anonymous
- Password: (leave blank)
- Connection Type: pserver
- Checkout As: Empty EMF Project
Modules
- You can check out the plugins in the org.eclipse.emf/org.eclipse.emf.jcrm/plugins folder as CVS modules
