Sine yesterday there where only fun activities on the schedule, the newbies from my group decided not come. So I had a free day, which I use work on the my thesis. I think that I will just design the metamodel after mof and then use xsl to transfrom it accordingly because the file format it not xmi.

After bbqing I went to tirili. Pics can be found in my gallery

After having the problem of ordered assoziations, 3 different options have be discussed:

1. Define a constrain type like before between 2 assoziations,

2. Define a meta-association from which all the other assoziations go off and the metaassoziation orders them

in the right way

3. Just use tags.

Well, none of the 3 solutions solve the problem because every information added would just appear in the xmi file but does not provide any order. So the only solution is to postprocess that information. So every association will be tagged, because the tag mechanism is allready provided by the mof model, while the other ones would require to define those elements first.

I still have no clue how to sort them later, but I will figure that out.

Yesterday was the first day of the Introduction week for the new students. I was tutor for the newbies. We should them the campus and gave them some information we thought that it might be usefull. Today there there are some fun activities, but since all the people in my group where from outside würzburg, they decided to take a day of, giving me the possibitlity to work on my thesis.

After trying to provide a MOF-compatible meta model for gast, i ran into one major problem:

how to order association. I don't know why the hell i came up with that idea that will just cost me a lot of time. The main usage is that i can use qvt, but i think i will hack something together because otherwise i will run out of time.

Now i have to face this problem. Using stereotypes is not an option, the are not available in mof, so no use. I could define my

one ones. Since they are defined in the infrastructure of the uml, it should be possible. But actually i don't want to do that.

One idea today was to see if its possible to tag the association itself, but i have to see if mof allows that.

but that will wait until saturday i think. the next 3 days i will be tutor for the new students.

Since everybody is blogging today, I just started my own blog. And since I'm lazy I installed wordpress as a blogging software

and now have a fully futured php/mysql blogger. I will try to figure out which nice features this software has.
