Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning.

Said by Rich Cook.

It happened on Wednesday and it was a lovely day because it wasn’t too warm and small clouds where all over the sky which was perfect for taking some outdoor pictures after the ceremony. For lunch we went to a local restaurant. Our parents had organized a champagne reception and Sabines sisters an ice cream bomb as dessert.

In the evening Sabine and I went to a local cinema for viewing the new film about Harry Potter. All in all a very happy day.

On Saturday we will also have a churchly ceremony and a “small” (eve-of-)wedding party.

1. Ralph Mueller gave us some infos about the Eclpse Foundation and the Eclipse eco system in Europe (PDF)
2. Alex Koderman talked about the verinice project, an open source solution for Information Security Management (PDF)
   Break
3. Tom Ritter spoke about Model Sharing in a Distributed Model-Driven Development (PDF)
4. Martin Flügge showed us Dawn, a web-based collaborative extension for GMF editors (PDF)
5. Eike Stepper gave us a talk about the Net4j signalling platform (PDF)
   Break
6. My talk was about how to COPE with long term metamodel evolution (PDF) and
7. Max Bureck spoke about a graphical QVT/R-Editor (PDF)

There was some kind of running gag due to the unawareness of the speakers to actually show a demo because of miscellaneous technical reasons.

In the beginning and during the breaks we had the opportunity to have nice chat and the advantage of a delicious buffet. Thanks to the sponsors.

After the camp some of us moved into a timeless restaurant for celebrating an Eclipse Stammtisch which was also very nice.

All together it was a long but very nice day.

Please note: There will be a second Eclipse Stammtisch on the 16th June where you will have the possibility to meet some members of the Eclipse Board of Directors. Please have a look at Eikes post announcing the Stammtisch. If you want to participate please enter your name into the Doodle poll.

During the last days I have prepared a paper about the thesis for the MDSE 2008 workshop in Berlin. After my two MetamodelDoc presentations this would be my third public talk but the first in English. I look forward to see you there.

Update: The thesis is now available for download in the Publications section.

I am back in the year 2008 – asking my self: “Why did I have kept the pages?” … Probably because of an article about Bresenham’s line algorithm in 16-bit-assembler(!).

Using search engines, news groups, forums or mailling lists  on a daily basis – life has become so easy…

The thesis was written about the creation of a graphical editor for a model driven software development process. The abstract follows below:

„base“ is a model-driven software development environment for internal use by „b+m Informatik GmbH Berlin“. For editing models in „base“ a tree-based editor has been used in the past, which builds on the Eclipse Modelling Framework (EMF). A tree representation in particular is difficult to manage for the dataflow model, because conceptionally the model represents a graph in the mathematical sense of the word. The objective of this thesis was essentially optimizing the developmental process in „base“. To this end, a graphic editor for dataflow models was developed on the basis of the Graphical Modelling Framework (GMF). The meta-model, on which the dataflow models are based, contains 20 element types, which can be placed directly in the editor’s drawing area. The complexity of the models used in GMF increases over proportionally though with the number of element types and is consequently difficult to administrate. This was the reason for developing „GenGMF“ instead of implementing a graphic editor with GMF itself. „GenGMF“ is a Domain Specific Language with an appropriate generic model-to-model transformation for the automatic construction of GMF models. The dataflow editor was modeled using this new development for the construction of graphic editors. Using „GenGMF“ for development of the dataflow editor allowed construction of a „GenGMF“ model requiring 72% less model elements than generated GMF models. In addition, it did not have to be manually adjusted. The result is ease of use for presentation in the graphic dataflow editor.

If you have any questions regarding the thesis, „GenGMF“ or „base“ just send me a note.
