You'd have to do it manually with your MWE, yes. 2) You benefit from this by reducing the amount of projects and the possiblity to reuse common code without cyclic dependcies or the need of yet another project to store shared classes. 3) Unfortunately, I haven't published the source of the chess example yet. I am planning to discuss the solution and provide the project complemented by a screencast, soon. This will be a dedicated blog post. Hi Dalaman,

1)currently there’s no guided process to place more than language into a single project. You’d have to do it manually with your MWE, yes.

2) You benefit from this by reducing the amount of projects and the possiblity to reuse common code without cyclic dependcies or the need of yet another project to store shared classes.

3) Unfortunately, I haven’t published the source of the chess example yet. I am planning to discuss the solution and provide the project complemented by a screencast, soon. This will be a dedicated blog post.

I also read the user guide of Xtext(http://www.eclipse.org/Xtext/documentation/0_7_0/xtext.html#generator), and in the Configuration.generator.GeneralArchitecture section it says that I can have more languages for one generator. 1- How do I do this? Can I specify two language definitions somewhere in the new Xtext project wizard or is it, that I can "register" my second language in my mwe file as a second declaration? 2- What is the benefit of doing so (having two languages for one generator) except that I don't have to write a second mwe file for my second language? Thanks a lot for the answer! Dalaman Hi,

You are describing something Karsten and I have talked about at the <a href="http://www.1160pm.net/2009/06/17/impressions-of-code-generation-2009/" rel="nofollow">Code Generation 2009</a> where we enriched UML models with technical details described via Xtext. Yes, it is possible to refer to other models graphical or textual from your Xtext model. Regarding your second question: sure! Two languages can base on the same meta model. If you describe these languages properly you can separate different aspects into physically separated files as well. We are planning to address the former at the seminar. The latter won't fit due to time constraints. Anyway, thank you for your questions. I will try to demonstrate this in the future. If this is urgent, please ask specific questions at the newsgroup. See you tomorrow! Thank you for your input, Valentin.

One should be a textual DSL that I create using Xtext for the dynamic view of the system and special aspects (stuff that is easy to model, but hard to model in UML). For the statics of the system I use a UML 2 Class Diagram. Is it possible to reference from the Xtext Models to Objects from the Class diagrams? (Somehow include the UML2 Metamodel and have xpath like expressions? xmi:id are not viable, because the UML Model will change as well over time). The other thing: Can I have two different textual DSLs to describe two different aspects of the system and one coherent metamodel. The two model types should be parsed and the unified metamodel should be instantiated. Then I want my generator templates to work on the one metamodel instance, because the templates should be agnosic to how the metamodel was instantiated. I am looking forward to wednesday.
