Next major version of Eclipse OCL

[marcadetd]

Hi Ed,
It seems that the ewillink/flatops branch will be the next major version (7.0.0) of Eclipse OCL: is-it right? Is there any planned date of release?
Regards,
Dominique

Yes. I'm taking the opportunity of a major release to do a major cleanup.

Unfortunately this occurs as 'maintenance' so all the existing OCL and QVTd JUnit tests slow me down / keep me honest.

Flat in 'flatops' refers to the rationalization to have three distinct perspectives of OCL metamodels:

• the primary/partial (definition) metamodel representing the normalization of UML/Ecore/...
• the complete (analysis) metamodel supporting the open classes that merge multiple metamodel contributions
• the optimized (execution) flat metamodel suitable for efficient execution

A FlatClass has fast lookup for the exactly one Operation and one Property for each feature. Vertical inheritance and horizontal complements are flattened. The four OCLstdlibTables/OCLStdlib/PivotTables/OCLmetmodel compile-time generated classes will be folded into just one. Only the very small number of applications that modify OCL will need dynamic run-time versions.

I was hoping to get 7.0.0 out for 2025-09 but it's still quite some way off.

And of course I get distractions such as rescuing UML2, and helping with the Acceleo 4 migration of MoDisco.
