UML diagram

[Philippe LeGrand]

Hello all.

I am trying to learn more about the internal design of Thuban, and I
noticed that a UML model exists, but the .xmi file fails to open on all
the systems that I have tried (Eclipse on multiple platforms, Umbrello
on Kubuntu & an old Debian, etc.)

Does anyone else have this problem? Is there an updated version
somewhere?
