#3 Identify API/Driver/ORM that can be used with MongoDB, Google data store

[Khurshidali Shaikh]

Identify API/Driver/ORM that can be used with MongoDB, Google data store. The idea is to implement diff persistence layer for MongoDB, Datastore but without having to add imports or annotations at model level which are specific to MongoDB or Datastore.

A JPA kind of annotation may work well. Need to find JPA support for MongoDB. For Datastore this seems to be present already.
