Hi Jannik,
you should definitely talk with Mircea who is planing to create a FAMIX Corpus. He wanted
to create something more complex than a bunch of mse files on a server. He was trying to
identify useful metadata to add to the files to.
Anyway, I like the idea and yes from the point of view having a mse files repo I think
the only mandatory meta-data are: name and version of the extractor used to create the mse
and the version of Moose that can load the file. Other simple meta-data could be: name and
version of the extracted system, language of the system, and number of classes and methods
(just to have an idea of the system size).
Indeed this was in really early version of famix and after we lost it.
Metadata is important. Guillaume and andre also worked on how to manage versions so that
we can compute different trend analysis.
We discussed also with usman about the structure of a typical project
- original files
- maximum import mse files
- shrunk mse files (because to compute certain metrics we do not need to load the
complete use files - size problem)
A project should be a FAMIX entity so that we do not fill up code with path and other
uglies.
And so that we can query
Project
allProjects
Project
named: 'Azureus';
loadLatestVersion
…
If people want to discuss and join I think that this is needed for moose.

Hi guys,
Each time we need to do case studies in Moose, we have to select the software
application, in a certain version and probably without all the source code needed. This
results on evaluations that are probably not reproducible.
I think that we need to unify our efforts and share the mse files of our models. With
that, it will be not necessary to generate a FAMIX model each time we need one.
For now, I begun to generate the model from the Qualitas Corpus 'e'
(http://qualitascorpus.com/). There are 486 multiple versions of multiple Java systems.
The mse files are really big (more than 650Mo for Eclipse_SDK3.7). I tried to load the
biggest one in Moose, and it loads ! I just needed to attribute 2Gb of memory in the
info.plist file of Moose 4.6.
I propose to put the files on a server. For all the tar.bz2 files, I need 3.65Gb.
Now, we lack ok at least two pieces of information : (i) the version of verveineJ used
for the extraction. For now, VerveineJ has no version (I took the latest one). (ii) the
version(s) of Moose that can load the file. I tried one mse file with Moose4.6.
We also need a server that can accept all the files.
Any suggestion ?
Jannik
