[emft-dev] [EMFatic] Alignment with OCLinEcore

[Ed Willink <ed@xxxxxxxxxxxxx>]

Hi

Failure to obtain permission to bundle IMP Runtime for use by the 
MDT/OCL Examples editors forces a change of a approach. Fortunately 
Xtext provides a very attractive solution.

Support for the new EMF validation/setting/invocation delegates with OCL 
implementations requires an editor for Ecore files with embedded OCL 
expressions. MDT/OCL will therefore be developing (targetted at M7) an 
Xtext EssentialOCL.xtext that can be reused to support OCL document 
editing by a CompleteOCL.xtext and embedded OCLinEcore editing by 
OCLinEcore.xtext. EssentialOCL.xtext should also be re-useable by 
QVTr.xtext and QVTc.xtext.

Xtext would appear to make supporting simple structural languages such 
as EMFatic trivial.

It would appear that EMFatic and OCLinEcore will be so similar that it 
would be good to try to make them identical from a user's perspective 
and perhaps share any relevant customisations/quick 
fixes/validations/code templates.

     Regards
