Today I gave a mini-tutorial at the 5th International Conference on Software Language Engineering (SLE 2012) attempting to explain grammarware to meta-modeling researchers. Since grammarware is a huge area, I chose to discuss a selection of memes from grammarware, illustrated with examples from the Spoofax ‘technological space’ (as they say). Here are the slides. A recording of the talk may be published as well. Note that the slides do not have much text explaining what they are about. We plan to elaborate the tutorial material in an associated paper for the SLE 2012 post-proceedings.
