Adding OCL in a Ecore Metamodel [message #510994]

Hi everyone!. I'm trying to add OCL for specify restrictions and derived references in my ecore metamodel (the mindmap). I'm reading the book Eclipse Modeling Project: A domain specific language toolkit. In Chapter 3, Gronback show how do this activity. The problem is I have done and review the book twice and Eclipse not generate the JET templates in the templates folder and the code derived from the OCL Statements in the class implementation. I checked the source and its the tutorial: Christian W. Damus, "Implementing Model Integrity in EMF with MDT OCL. Well, I tried do it whit the Eclipse modeling project version and the modeling version of Eclipse (both Galileo) and in the two cases it doesn't work. Can somebody tell me how to add OCL in the Ecore metamodel in these versions?

PS: I read anothers post with the same problem but I don't find any solution in the order to solve this problem. Is important for me, because I have to develop a plugin's series in the form of UML profiles for a specific language to represent collaborative business processes models between business partners and I must to implement restrictions in the differents metamodels using OCL

I solve the problem. I looked for the samples of the book wich were in the org.eclipse.amalgam.examples.dsltk plugin and then I imported the mindmap example whitin the workspace and copy and paste the jet templates into my project. I think the templates from the tutorial are obsolote

Hi, Fernando,

The article isn't obsolete: it still works just fine with EMF 2.3! :-P

It does happen to illustrate one of the risks inherent in using custom
templates, though: as EMF's generator framework evolves, one's custom
templates do need to be updated to pick up changes from the EMF
templates that they replace. The EMF team does a good job of ensuring
that its supported extension and override points continue to work, but
can't really do anything to help people like me who completely replace
the base templates.

Perhaps you'd like to help complete the more modern solution proposed in
http://bugs.eclipse.org/191689 ?

Cheers,

Christian

Cristian,

I'm beginner in EMF, OCL and GMF so I thought that the templates doesn't work with my target EMF version (2.5) like you said. Maybe the word "obsolete" wasn't right. I don't remember if I test the templates of the article setting the genmodel on the EMF version 2.3 before regeneration!... I appreciate your invitation and I will post in a while!. I'm a MDA enthusiastic and I think that these frameworks are very productive and are aligned directly with the MDA approach so while I work in my project degree, I will share in these forums, all that I learn and I will post questions in order to solve problems that surely I will find!

Cheers!

Fernando

Hi Fernando, Christian

https://bugs.eclipse.org/bugs/show_bug.cgi?id=191689 has just sprung
back to life with the 3.6M6 API change deadline looming. Support for
the new way of doing OCL constraints will appear in MDT/OCL CVS in the
next week or two and will be available in the Eclipse M6 milestone and
subsequently the Helios release.

I'm sorry that in the interim the solutions are poorly described.

Regards

Ed Willink

Hi, Ed,

Many thanks to you and Kenn for working so diligently on this. The
prospect of finally having a complete validation solution in Ecore is
very exciting! And no less exciting is parity of dynamic Ecore's
capabilities with generated models.

Cheers,

Christian

Christian,

Yes, it's yet another fairly well hidden gem in the collection of crown
jewels. :-P

Hi Fernando, Christian

The OCL-in-Ecore support is now in CVS HEAD ready to appear in MDT/OCL
3.0.0M6. The associated OCL-in-Ecore Editor and the OCL Document Editor
will be committed as OCL Examples over the next few weeks.

A first attempt at documentation is available at
http://wiki.eclipse.org/MDT/OCLinEcore Comments welcome.

Regards

Ed Willink

Hi, Fernando Herrera

I am new on OCL in Ecore. I am using EMF 2.5, trying to generate src for my ocl annotations added into ecore model. I just fail to get the expected results. OCL contraints are never integrated into the generated code. I think the dynamic templates should be the issue. Can you tell me your solutions. What are the correct templates that works for EMF 2.5?

Hi, Yan Liang. Well, there are two ways to do the templates work. One is reading this article: http:// www.eclipse.org/articles/article.php?file=Article-EMF-Codege n-with-OCL/index.html . The templates provided work fine with EMF 2.3, so before generate the plugin's code in the genmodel file, set the EMF version at 2.3 and after that the code would be injected. The other way (in order to use the EMF 2.5 version), is with a set of different templates that I have. If you want them, please send me a email at: enferx@hotmail.com.

PS: The new version of Eclipse (3.6, Helios) upcoming will have this feature integrated in the GUI so you won't need to use templates for this work anymore.

Regards

Fernando
