Domain Model Migration and Sirius [message #1828272]

Hi,

Currently I have a domain model (metamodel), say the BasicFamily metamodel [1] and create a breaking change to the domain model (change the name of the "members" reference to be "people"). I can deal with this change in the semantic model by using tools such as Edapt [2] or Flock [3], but the .odesign model also needs to be updated for this breaking change. Is there a tool, or best practice out there for migrating an .odesign model for when the domain model changes?

Many thanks
Justin

Hi

To make this work correctly you need to load the primary and all subsidiary models into the same ResourceSet, then perform the primary model edit. All subsidiary models will then change automatically, Save the ResourceSet and all is good.

Easier said than done, but probably easier to get the tooling right once than run around afterwards with fixes. You may need to raise Bugzillas against the tooling for the subsidiary models.

Hi,

You may also be interested in the org.eclipse.sirius.business.api.migration.IMigrationParticipant extension point. I've never had the time to use it but it should help to automate the update of existing representrations.

Emmanuel

Hi Justin, Emmanuel,

The migration participant extension point allows to provide participants to migrate .odesign or .aird.
There are triggered during the load of those resources (during the VSM editor (.odesign), or during the Session load (.odesign and .aird).
The changes are serialized only if the save action is called.
VSM made with previous versions an deployed in plugins will be migrated during load from ViewpointRegistry.

Regards,
