Hi Ecore Tools dev team,

First of all I want to congratulate you for the tool which keeps getting better every time Smile

I'd like to ask you about the plans to integrate Ecore Tools with MDT OCL. Is this going to be done through the offered components in EMF Validation or is the component going to provide its own validation mechanism to work with OCL? You mention in the wiki plans to provide integration with EMF Validation, but I don't see any open bug for that; however 297650 talks about integration with org.eclipse.ocl. What is the goal of this integration? Is this documented anywhere?

Thanks a lot for your help!

-Juan

Juan,

Probably the new validation support added to EMF along with the OCL
project's exploitation of it will be of interest:
<https://bugs.eclipse.org/bugs/show_bug.cgi?id=216701>

https://bugs.eclipse.org/bugs/show_bug.cgi?id=216701

I think Ed Willink documented how to take advantage of that, but I
couldn't find it on the OCL wiki, so I've added the OCL newsgroup to the
"to" list of the reply.

Cheers,
Ed

Hi Ed, Juan

The write up is at http://wiki.eclipse.org/MDT/OCLinEcore

The first representation part is still valid.

The second editing part is not. It was written about six weeks ago since
when things have moved on a lot.

MDT/OCL 3.0.0M7 (on Wednesday) will include Xtext-based 'example'
editors for

- CompleteOCL which provides a OCL document to complement a meta-model
- OCLinEcore which provides a compound Ecore and OCL textual language
that may optional be loaded from/saved to an *.ecore file
- EssentialOCL a single expression for use in pop-ups
- OCLstdlib to define the OCL standard library

Watch this space/the Wiki for a revised write-up.

NB. The examples do not ship in the Helios Modeling EPP bundle, so you
need to load them from the MDT/OCL Update Site. Hopefully by Helios we
will have sorted out visibility through the Modeling Discovery UI.

Regards

Ed Willink

Hi Ed,
today I try to follow your wiki entry.
But I fails in the beginning.
After installing Eclipse 3.6M7 and MDT/OCL 3.0M7 I generate the Library
Example and try to open the ecore model with the OCLinEcore Editor.

I've got an event loop exception:

Hi Heiko

I'm afraid that installing the Xtext editors is fraught with many
difficulties.

The underlying Xtext APIs changed between M6 and M7 so that an MDT/OCL
M7a is imminent to ensure M7 coherence.

Last night the M7 plugins were not yet in the staging area so installing
the trial M7a grabbed incompatible Xtext M6.

The load of *.ecore is limited to rather simple (no references to
another model) Ecore files. Bug already fixed, but not in M7a, which was
enough of a build trial without fixing bugs.

I'm afraid that in M7 the editors are a bit of a taster for treats in store.

Regards

Ed Willink

Hi Heiko

I'm afraid that installing the Xtext editors is fraught with many
difficulties.

The underlying Xtext APIs changed between M6 and M7 so that an MDT/OCL
M7a is imminent to ensure M7 coherence.

Last night the M7 plugins were not yet in the staging area so installing
the trial M7a grabbed incompatible Xtext M6.

The load of *.ecore is limited to rather simple (no references to
another model) Ecore files. Bug already fixed, but not in M7a, which was
enough of a build trial without fixing bugs.

I'm afraid that in M7 the editors are a bit of a taster for treats in store.

Regards

Ed Willink
