Well, there is Orbit, a MVC framework for Kepler that is somewhat like
Rails. The plan is to integrate it with Saci, a LuaSQL based ORM, (equivalent
to ActiveRecord) and use it as a higher abstraction over
CGILua.
But
this is all still preliminary work (both Orbit and Saci are in pre-alpha) and
our focus now is on platform documentation and the new release of Kepler and
its current set of libraries.
