Hi
You can try to find the UML diagrams made by the old EDG ATF and EGEE
PTF (try asking Erwin Laure). For the LCG-CE and LCG-RB the diagrams
will still be about right; for data management they will be completely
different.
Maarten Litmaath has a different type of diagram, but with similar
information, for both the lcg and glite WMS/CE combinations.
You could try contacting the DM folks directly (I suggest Akos Frohner);
I know at some point he had constructed similar UML diagrams for some
components, but as this was some time ago I don't know whether they
referred to an earlier stack (e.g. Fireman) or the current stack.
