Good technical presentation. It would be good to explain how this solution makes developers more productive than other parser generators however. Also, how are MGrammar and MSchema better together?

Also, I was incidentally looking at a cool web tool which uses a DSL to generate UML diagrams (http://www.websequencediagrams.com/). Digging some more into it, I found out language specs for UML (such as http://www.itu.int/ITU-T/studygroups/com10/languages/Z.120_1199.pdf) and that made it clear that any DSL language needs to be very well speced and documented. The presentation didn't demonstrate those aspects.

I'll put a plug for my codeplex project:
NPEG is a c# peg parser.

Technically, OMeta is a PEG parser, which implies a top-down parsing strategy and a "scannerless" parser (no separation between tokenizing and parsing). MGrammar is an LALR(1) bottom-up parser with a conventional DFA-based tokenizer; the MGrammar language has separate constructs for defining tokens and for defining parse productions.

I'm not sure that was the level of detail you were asking for, but that's the situation as I understand it :-) The MGrammar folks intend to produce a white paper on this at some point, but haven't yet.

Any comments about the relationship between MGrammar and OMeta?

I will probably attend the session later today. I'll try to put up a summary on www.larswilhelmsen.com - The webcast & PPTX will also be available tomorrow or something.
