Thanks for sharing.

Just to be sure, If I understand well, the realm data store (on mobiles devices) is fully open source (Apache 2.0). I think it was not the case at start in 2014 but it is now. They are seen as an alternative to SQLite. https://github.com/realm <https://github.com/realm> This is the other component of the architecture that is closed source (the realm object server). > > I am happy to help you out though - I've written a LOT of persistence active > record type things and am pretty dang handy with GLORP as well. > > Drop me a note if you want to collaborate.
