srs and domain model approved

today we approved at the meeting the srs and the domain model.
we dsicussed also the sequence diagrams and the architecture draft. i'll extend the architecture tomorrow and then start with the class diagram. so that i can start with the implementation at Thursday.

today i took a look at the perspective wiki engine. but i think, it's not usable for our needs. because with a wiki engine, you can edit the whole page. but in our case, the user should be able to edit only a part of the page. i'll describe this in the design document, which i just created.

in the srs i refined the last use case. so i think we have now a solid srs, which we can work with.
