Implementation.jpa and other data access efforts
I have started reviewing and adding implementation.jpa [1] to Tuscany
SVN. I was wondering how would that relate to the other efforts being
done related to data access, and if we should align this to the same
direction. Maybe we could have something like :
- implementation-data-xml
- implementation-data-sdo
- implementation-data-pojo / jpa
Thoughts ?

The current implementation-openjpa is exposing the JPA EntityManager
and from that point, the developer is exposed to all the JPA API to
handle the data crud operations. I think there is room for
improvements here, were we could abstract the JPA API as an
implementation detail of a implementation-data-pojo / jpa, that would
use the JPA api's under the covers.
Thoughts ?

On the face of it it sounds like a good idea.
Is there some abstraction at the implementation-data level. I expect (but
don't know) that these implementation types will all be providing access to
data in various forms. The current implementation-data provides a CRUD style
interface. Implementation.openjpa seems to favour persist, find, createQuery
etc. What will xml and sdo be providing?
