How do we do that?

Well, we supply software for new libraries - absolutely #freesoftware as in beer, and can even aid with some #hosting costs so there's nothing out of pocket.

For existing libraries, which might already have systems they can't easily migrate off of, we can provide #adapters so that the MoP software can provide an #API for use in federation. The current code is setup using #objectorienteddesign to do just this - each system will need an adapter written though!
