Ideas for a RoadMap of TopLinkEssentials

This is totally uncommitted, just conversation fodder at this point.

From Doug Clarke @ Oracle

We are working on a roadmap that lays out our plans for TopLink Essentials. We are hopefully going to review this with Sun and get it published in the near future. The goals we plan to address in the roadmap include:

• Improved visibility and brand recognition of TopLink Essentials. We need to be growing the community and user base.
• High priority ER's filed and voted on in the GF issue tracker
• Several Advanced/Extended ORM initiatives that will expose functionality beyond JPA

The success of TopLink Essentials is also dependent upon addressing the bugs and enhancement requests of containers other then GlassFish who are leveraging us. We need to try and address what we can and also try our best to ensure our schedule produces functionality that can be included in these container's releases. Addressing these issues and schedules will be challenging.

Currently I am aware of the following containers including or certifying TopLink Essentials as their JPA implementation:

• GlassFish
• SunAS
• OracleAS 10.1.3.1
• Spring 2.0
• JEUS (Tmax Soft)
• EasyBeans - JOnAS EJB 3.0 Container

As far as release/milestone dates we are currently working to the GlassFish schedule since TopLink Essentials is a module of this project.
