Oracle Toplink is now open source

Oracle has released the Toplink O/R mapping framework as open source. They proposed a new persistence project, named Eclipse Persistence Platform (or EclipseLink for short), at the Eclipse Foundation and they are donating the Toplink source code to start the project.

The EclipseLink will be a runtime project offering only libraries and no IDE tooling. Other Eclipse projects, like Dali, offer tooling for JPA and O/R mapping. The project will include the Toplink O/R mapping tools and APIs, a JPA implementation, an OXM framework, a SDO implementation and other persistence related technologies.

Toplink is a very mature and successful product. It is maybe the fist successful O/R mapping product for Java and it is great to see Oracle donating it to the open source community.
