This is interesting! It seems to have a large overlap with the Juneau project in the Incubator, which can map annotated beans from/to various formats, including RDF with Jena.
http://juneau.incubator.apache.org/#about.html Sesame in the olden days had something called Alibaba which was very similar, but since abandoned, I think it also had such an EntityManager. Would this module be particularly Jena-specific? I would think PA4RDF could work well with Commons RDF and then be useful without having to pick an RDF implementation. (except I guess you use Jena for mapping to native types?).

It basically turns any RDF subject into an object with the predicates defining the properties of the object. The current implementation can apply the annotations to interfaces, abstract or concrete classes. It has been used in several projects with different corporate and government owners. I would like to contribute the code and documentation to the Jena project as an "extras" project. Further information about the project and the code can be found at https://github.com/Claudenw/PA4RDF. Is there any objection to accepting this contribution?
