The relation between OCL and graph patterns (pun intended)

My previous introductory blog posts talked about the importance of modeling, the concept of model queries (with OCL and EMF-IncQuery) and model evolution. Now it is time to give a glimpse into my research: translating OCL expressions to graph patterns, so that incremental evaluation techniques (see EMF-IncQuery) developed for graph patterns can be applied to queries formulated in OCL.

Change or die: model queries on evolving models

...the only constant

Modeling and model queries were discussed in my previous blog posts. Now it is time to turn our attentions towards a great challenge: that of evolving models.
