[news.eclipse.modeling.mdt.uml2] Re: Reading UML Profile Elements in Jav

[Kenn Hussey <Kenn.Hussey@xxxxxxxxx>]

Dawid,

I'm glad to hear that it's working better for you now (but I'll take a 
pass on the kiss)!

1. Yes, this is expected; basically, everything in the resource that was 
encapsulated within XMI extension elements will be instantiated as 
AnyType elements and captured in the extension map for the resource. If 
you aren't interested in preserving these elements, you can simply 
discard them.

2. The 'String' primitive type is actually supposed to be part of the 
standard metamodel rather than a profile, but this is an example of the 
differences you'll see between the way tools interpret the UML 
specification. Interchange of profiles and stereotype applications is 
generally a challenge as a result, so unfortunately you will likely run 
into problems unless the model you are trying to open/import is in 
"native" Eclipse UML2 format... For information on how to work with 
profiles in UML2, please see the "Introduction to UML2 Profiles" article 
on the Wiki.
