I would only promote what Seth would prefer promoting.
Having an API could be a better solution, as it would allow to provide a
unified front-end to annotation packages while letting annotation to be
stored in a number of different backends (loaded environments like it was
the case, the coming SQLlite ones, remote SQL database, web-service,
Having an API would also permit to make changes to the SQL schema without
causing a lot of trouble to all users.
