Thanks, that's nice to hear. There are certainly generalizations that have arrisen, we're not building this out of thin air but with reference to a lot of work done over decades (semantics, standards, pre-existing tools). It's open source, there is significant infrastructure there that could be grabbed and re-factored or extended to meet other needs. Of course the whole project is also a test of the oft stated, rarely proven "open-source it and people will join/contribute" too ;).
