Re: [mdt-papyrus.dev] [Model Repair] Profile package naming schemes
Hi, Martin,

IIRC, the reason for this fairly restrictive pattern was to try to limit certain automatic decision making to packages that "look like" profiles.  Evidently, this did produce some unhappy effects.

I know of no plan to add extensibility or any other changes to this repair component, but it would certainly be a good contribution.  Best to start by raising a bug and, if you have an idea for a solution, work up a gerrit.

Thanks,

Christian

Dear Papyrus developers,


I am working on integrating part of the model repair functionality [1], i.e., the profile migration, in EMF Compare.

Papyrus automatically triggers this profile migration for zombie stereotypes, i.e., stereotypes whose defining package cannot be found [2].


During the migration, zombies are grouped based on the expected package scheme in order to migrate to a newer profile / package.

This grouping is important, because all zombies of a group that cannot be migrated with a newer package get deleted [3] from the model and only the successfully migrated ones remain.


Currently, this grouping mechanisms is based on the pattern "^http://.*/([^/]+)/\\d" [4].

This means packages must have some kind of numbering at the end to produce separate groups, e.g., http://www.eclipse.org/my/profile/version/Language/7 is fine, but both http://www.eclipse.org/my/profile/version/7/Language/PackageA and http://www.eclipse.org/my/profile/version/7/Language/PackageB get reduced to http://www.eclipse.org/my/profile/version/7/Language#/ [5].

As a result, more stereotypes are assigned to a package than expected and those wrongly assigned will get deleted.


Is there a way (currently or planned) to extend this matching mechanism to also support different profile package naming schemes?


Thanks in advance!


Cheers,

Martin
