Hi all,
I would like to extend a UML UseCase Model by an ATL transformation. The
extended (or target) Model should contains Classes which are derived
from the UseCases. If I write something like this:
rule Model{
from m1:UML2!Model
to m2:UML2!Model(
name<-m1.name
)
}
The xmi id of the Model has changed, but I need a transformation that
keep the xmi id's or otherwise I need a possibility to collect traces.
Is there already something that could helps me? Maybe a transformation
or a workaround that provides me a solution of a kind of a copy
transformation of the model or an in-place transformation mechanism?
I'm not familiar with ATL very well, therefore I wonder if somebody has
already solved my problems ;-)
Thanks in advance
Christian

Hello,
Could you please prefix the subject of your ATL-related posts to this
newsgroup with [ATL], as I did in this reply? Thanks.

About model transformation traces:
http://www.eclipse.org/m2m/atl/atlTransformations/#ATL2Trace r
or, better (i.e., using model weaving with AMW):
http://www.eclipse.org/gmt/amw/usecases/traceability/
About XMI ids:
It is possible to get the XMI id of an element using the __xmiID__
property (e.g., m1.__xmiID__).
However, it is not possible to set the XMI id yet. It would not be very
difficult to implement it, but playing with XMI ids does not seem very
"clean".
About in-place transformations:
ATL refining mode can be implemented using an in-place mechanism,
provided the semantics of ATL is followed. However, I am not aware of
any such implementation existing yet.

Frédéric Jouault
