[mdt.dev] MDT/OCL Text Editor and EMFT Model Registry suggestion

[Ed Willink <ed@xxxxxxxxxxxxx>]

Hi All

In https://bugs.eclipse.org/bugs/show_bug.cgi?id=261742 #2
Christian Damus revealed that we are discussing migrating
the (currently M2M/QVT Declarative) OCL Editor to MDT/OCL.

This incurs two dependency problems.

The text editor uses IMP, which is an incubation project,
so the additional optional MDT/OCL editor plugins might
have API stability issues. IMP has hopefully only very
minor IP issues.

The semantic validation of OCL requires a solution to the
problem of where is the (potentially user-defined non-plugin)
package named Xyzzy? The (currently M2M/QVT Declarative)
Model Registry solves this problem. The Model Registry
was originally part of UMLX, it has moved to QVT Declarative.
A further move of generic modeling functionality to MDT/OCL
does not seem right. Therefore a new EMFT project seems more
appropriate.

Kenn, Ed, Rich, Frederic, Jean, ...  Please advise on how best
to proceed with a fairly small EMFT Model Registry project.

All: Please be aware of the plans and please comment, especially
if you have ideas or available resources for further Model Registry 
development.

Please respond on mdt.dev only.

Attached PDF provides more background on the project dependencies.
