Description Jeppe Cramon

Build Identifier: Indigo 20110615-0604

Christian provided a nice introduction to how one can use UML2 based models with Xtext2 on his blog http://christiandietrich.wordpress.com/2011/07/17/xtext-2-0-and-uml/

But IMO it's unreasonable to expect anyone to put this kind of effort into having Xtext work with UML2 models. Working with UML2 models should be as easy as with ecore models.

Would you consider making a default implementation of what's in Christians blog post and make a "Xtext project for existing UML2 model" (or something like that) project wizard, that would set plugin dependencies, setup MWE2 correctly, etc. ?

Reproducible: Always

Steps to Reproduce:
N/A

There is a big difference between "creating a textual syntax for an UML model" and "allowing cross-references to point to UML-Elements". Christian blog post is talking about the second scenario. These steps acre actually necessary for every "foreign" EMF model that you want Xtext to index.

Hi Mortiz

The name for the wizard was badly chosen, thanks for pointing that out :)
A name like "Xtext project with UML model referencing" is probably a better name.

My point is that it shouldn't be necessary to configure and program this much (e.g UmlResourceDescriptionStrategy, UmlRuntimeModule, UmlQualifiedNameProvider, UmlSupport, UmlUiModule, etc.) to get UML referencing working with xtext. 
UML is pretty commonly used and if you want further adaption of Xtext, then you shouldn't make too hard for UML people to get their models working with xtext. 

There's simply so much knowledge packed in Christians blog post, that people starting out with xtext shouldn't need to care/know about. Don't make it too hard for them to like xtext. The learning curve is steep enough as it is ;)

So if you would provide the default implementations for referencing UML models, it would also be really nice if you could provide a wizard that could setup uriMappings, registerGeneratedEPackages, registerGenModelFiles, pluginDependencies, etc.

I'm inclined to close this as won't fix for Xtext core. Any objections?

Could it be moved to a sub project or don't you agree that it could be valuable for people coming from a more traditional UML background?

We don't think using UML in the context of DSLs is a good idea in general. There might be cases where UML just is what you need, but coming up with a wizard doesn't fit with our thinking of UML :-)

How about having such extensions in a separate project at Eclipse Labs? I'd be happy to list it on the Community page.
