Hello,
I have a UML profile which is applied to a UML class diagram. This profile
has several invariant constraints which are applied to the stereotyped
elements. I would like to use ATL to verify the validity of the stereotyped
class diagram with respect to my profile.
I have seen in the paper "Using ATL for checking Models"
( http://www.sciences.univ-nantes.fr/lina/atl/www/papers/GraMo T05.pdf) that
the authors implement their strategy in an Eclipse plugin using EMF.
I am thinking in creating the ATL transformation which define the stereotype
constraints as is explained in the paper and applying that transformation to
my stereotyped class diagram. But I don't know if it is the right solution?
Thanks in advance
Bea

Hello,
I would argue that representing a diagnostic (i.e., the result of
checking some constraints over a model) as a model is actually simpler
to integrate in a Model Engineering scenario (sequence of
transformations). This is especially the case with AMMA, which is guided
by the principle "everything is a model".
For instance, the TCS compiler (i.e., from TCS+KM3 to an ANTLR grammar)
uses this approach.
Before running the TCS2ANTLR.atl transformation, the TCS2Problem.atl
transformation is executed to check constraints (it is implemented
following the scheme presented in the "Using ATL for checking Models"
paper).
Because the source model (i.e., the .tcs file) uses TCS, the problems
can be reported within the editor using the am3.applyMarkers ant task.
See:
TCSSample.zip\TCSSample\TCSToolkit\TCS2JAR\build.xml
(zip available from http://wiki.eclipse.org/index.php/TCS).
The KM3 compiler (i.e., KM3 to Ecore or KM3 to MOF 1.4) also uses this
approach, but was implemented before the AM3 ant tasks had been created.
Therefore, it uses Java code to launch the KM32Problem.atl
transformation. However, this shows that you can also integrate this
scheme within Java code, should you prefer this over ant tasks for some
reason.
Best regards,
Frédéric Jouault

Hello,
If you follow the scheme presented in the paper (i.e., a --2Problem.atl
transformation), you will get the diagnostic as a model.
You may then do whatever you want with this model. For instance, you may
use TCS to get a textual representation of the diagnostic.

Frédéric Jouault
