EMLS 2015

We will have (hopefully) our EMLS workshop again at SE 2015 in Dresden. The primary goal of that workshop is to bring people together working on common issues to foster their collaboration. Therefore, we encourage people to submit interesting collaboration ideas, research questions, case studies or case study plans, or other initiatives to the workshop when it will be announced on 1st December 2014.

MODELS 2014: A Personal Review

Yes, I know, MODELS was in September and such a late review is kind of awkward. However, I was quite busy in the last couple of weeks. So the review had to wait.

First of all. Models was great and the extended summer (from an almost Scandinavian perspective)  was also very motivating. I should remind myself to go to the south of Europe every September.

The workshops, I attended, were also very interesting and enlightening. In the reviews to my doctoral symposium paper were very motivating, especially because the term “relevant for research and industry” was in there without a negating in it. The meeting itself was also fascinating (thanks to Benoit Baudry and the reviewers).

I also attended an workshop on deep modeling which provided some good insight into different approaches in that field and where they differ. In the end we had quite an active discussion on what to do with the workshop and with this emerging field as such. In short you could say that the different approaches are diverse and therefore comparing them on term of quality is complicated. Especially because the vocabulary is not unified. Therefore, one result of the discussion was the creation of a glossary for common terms to be able to come up with a method to compare the approaches. And someone coined the NoUML as a summarizing term for all deep modeling approaches as they are to UML as NoSQL is to SQL. Even though it was a funny remark, especially knowing that Models started as an UML conference, I think the term is good enough to cover all of the presented approaches and even allows to come up with a total different modeling concept without leaving the field immediately.

On Monday, I visited a tutorial on language modeling principles. As I am very interested in that field, I wanted to know if I can meet some interesting people there (which I did). While most of the tutorial was not completely new to me, Ralf Lämmel presented it in an interesting way which also provided some deeper understandings of the different parts and views of the principles. I was especially intrigued by his definition of mega models. I still do not like the name, as I find it – personally – not very descriptive. However, his definition was concise and expressive.

Here it is: A mega model is model which specifies the relationship of different models to each other. A model is that context could be a model, a meta-model or a transformation. And a relationship between two models could be conforms to, (as in my VAO paper this year) an aspect base model relationship or many more.

Subsequently, we used the notion of mega models to formalize the big picture of our iObserve approach which we integrated in one of our recent publications (which will hopefully be accepted).

So all in all Valencia was quite thrilling and productive. So I look forward to go to Ottawa next year. And maybe we are able to publish my generator composition approach at ICMT 2015 which would be a great development.
