UML2 specifications, metamodels and profiles

[SF_lt]

UML2 superstructure is adopted 2004-10-02, infrastructure specification is under reviewing, proposal is dated to 2003
OMG's site states, that OMG members can access revision versions - it would be great to get the latest infrastructure revision version. Can someone share it?

as I understand, metamodel should be created before developing UML profile (except cases, which are quite trivial). However, there is great lack of the articles/tutorials, how to do this - profiles development in examples.
Still, haven't found anything better than Lidia Fuentes article :-)
"UML bible" book only mentions about existing profiles, parts of the profiles, but no more :-/

Could you expand a little more on what it is you need to do?

[SF_lt]

don't know exactly, which part:
1. just for curiosity
2. have modeling technique based on aggregates and need to create UML profile for it. And there is no good source to learn how to create profile (at least, can't find; not EA profile)

I once uploaded a little sample at EAUG. You may look inside and use it as a start.
