Broken Links within RSM Diagrams to regenerated Models [message #628128]

Hello everybody

I'm quite new to oAW/MWE and try to point out a problem I was faced with recently:

I'm using Xtend for M2M generation. The generated models will be used further for M2T AND for documentation purposes in a SAD (software architecture document). I'm using RSM (rational sofware modeler) to develop the SADs. The generated models are presented in diagrams.

Problem:
The links to the models (emx files) are not stable when the model itself is regenerated. The reason: xmi:id's are always regenerated so the diagram's references to the entities (linked with xmi:id's) are broken if you regenerate your models!

Question:
Is there a way to force Xtend to generate the xmi:id's always in the same manner? To make sure that each entity gets the same xmi:id as in the last generation run? Therefore my diagrams would not have broken links and the MDSD chain would be complete.

Thank you for your advices, I hope I could explain the problem properly.

Regards, PHil

I am not familiar with oAW and RSM, but you can search if a parameter
exists in order to generate with a fully qualified name as ID (ie
replace a number rank by the package.subpackage.calss name).

Bonjour Vincent!

Merci beaucoup pour ton message. Wink

Can you explain where I can "switch" the way of ID-generation from this standard identifier e.g. "xmi:id="_ExoIx8WQEd-cM66Qq7KqLg" to the fully classified class name?

Can I make this in the workflow files (.mwe) or do I need to code some java?

Cordialement, Philipp

I do not know oAW and other tools you use so you may explore their
preferences and/or documentation :-(
