Tijs van der Storm is talking about some of the Meta Modeling work that goes on here at CWI. In some ways, this talk is reminding me of the OMeta talk at StS - I'll let the experts decide how much overlap there really is :)

About 37 minutes in, Niall Ross asked specifically about this stuff compared to OMeta. So - OMeta uses PEGS, they use SDF. And their work is less general than OMeta - they are targeting DSLs, as opposed to general language development.
