Hi,
I'm really interested by the TCS capabilities, jointly used with ATL.
In our case, we have decided to use a UML profile to give a graphical
concrete syntax to our DSL, using the Papyrus customization capabilities
to rapidly have a dedicated editor.
We'd like to also associate a textual concrete syntax to this DSL , and we
were wondering if TCS would be able to directly associate this syntax to
the UML+Profile metamodel.
The other solution I see is to use an intermediate DSL meta-model with a
transfo from this one to the UML+Profile, but this solution will imply
bigger efforts when the metamodel of our DSL will evolve.
Would you see any other solution?
Thanks for you help,
Best regards,
Sebastien

With TCS you can define textual syntaxes for specific metamodels.
In case you have a DSL that is not defined as a metamodel but by another
mechanism (e.g., a UML profile) you need to create a metamodel
representation of your DSL. This corresponds to the "other solution"
that you have identified.
In any case, it may be necessary to deal with evolution:
- updating the TCS model when the metamodel evolves,
- updating the metamodel when the DSL definition evolves,
- etc.
I would recommend using transformations to automate most of these
problems. This may for instance be a transformation to automatically
create the metamodel from the DSL definition (e.g., UML profile).
Note that it may be easier to transform a metamodel into a UML profile
than the reverse operation. Therefore, you may prefer to define a
transformation from the metamodel to the profile.
I personally like this solution because you have a simple representation
of your DSL as a metamodel (abstract syntax) plus the definitions of two
concrete syntaxes:
- Graphical, using a transformation to a UML profile,
- Textual, using a TCS model.

This is an interesting issue. Please let us know the results of your
investigation :-).
> Thanks again for all the nice work you do,
You're welcome, and thanks.
