Adding constraints to UML Profiles in Papyrus [message #997587]

Tue, 08 January 2013 08:38

Hi,

Recently, I've developed my own UML Profile using Papyrus.
Now my doubt is how can I add/associate OCL constraints to it?
My goal is to validate if a model that applies my profile is correct or not.

I'm using the following version of Eclipse:
Eclipse Modeling Tools
Version: Juno Service Release 1
Build id: 20120920-0800

Thanks in advance,

Hello André,

This feature is not supported in the current version of Papyrus. It should be supported in 0.10 (June 2013, Eclipse Kepler)

Camille

Thanks for the answer Camille.
Is there any other way I can perform this validation?

Thank you once again.

Hello,

I guess you can implement your constraints in a new EMF Validation plug-in. Papyrus relies on this mechanism for validating the models.

Camille

Hello,

Just in case you need it - a tutorial is in the EMFV help:
http://help.eclipse.org/galileo/index.jsp?topic=/org.eclipse.emf.validation.doc/references/examples/oclValidationExample.html
(The link is from galileo - you should find it in the local help of your installation).

The feature shipping with Juno is:
EMF Validation Framework SDK 1.6.0.v20120328-0001-67T-96SGR75UNqZNTdeQnghI6uFA org.eclipse.emf.validation.sdk.feature.group Eclipse Modeling Project
(You get it if you install the Modelling package)

Ok, I will explore that option.
Many thanks Camille and Vlad.

Hi

The EMFv OCL tutorial is seriously old; a patch was supplied for Juno
but never applied. https://bugs.eclipse.org/bugs/show_bug.cgi?id=327956

You won't get very far trying to get profile constraints to execute
since EMFv ignores stereotype applications.
https://bugs.eclipse.org/bugs/show_bug.cgi?id=397508

You won't get very far trying to get profile constraints to execute
since there is no ConstraintProvider for UML Profiles.
https://bugs.eclipse.org/bugs/show_bug.cgi?id=397519

These are problems I have fixed in the last week. You may find that
things are much better with the Kepler M5 release (3 Feb) of MDT/OCL
which can be installed on Juno.

Hi Ed,

So you suggest that the best option for me right now is to wait for the Kepler M5 release (3 Feb) of MDT/OCL?

Thanks for the reply.

Hello everyone,

I have some additional comments.

1. I have used EMFv exactly as described in those tutorials and it worked with eclipse 3.7.2. So I think it's worth giving it a shot on 3.8 / 4.2.

2. I think EMFv, as it is, does have some advantages over alternate methods described in https://bugs.eclipse.org/bugs/show_bug.cgi?id=327956 .
* Constraints can be given IDs, can be grouped, documented and made visible for the user in the Properties pages.
* The oclinecore editor does not support any ecore model - so for the unsupported model the user has to edit the annotations with the sample ecore editor - which is cumbersome.
(e.g. eKeys are not supported - Is this still true ?)
* EMFv has support for live validation

3. @Andre: What exactly the constraints must constrain ? Do you have to access meta-properties defined by the stereotypes ?
If you only need standard meta-properties to express constraints, then EMFv should work.

In addition to the UMLProfileConstraintProvider, you may find the new
CompleteOCLConstraintProvider useful in M5. This makes the Complete OCL
constraints visible in the Preference pages.

There is a faint possibility that
http://wiki.eclipse.org/MDT/OCL/Debugger#The_Validations_View might
appear for Kepler.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=324924 was fixed for
Indigo (20 months ago).

Without a UMLTraversalStrategy, the stereotypeApplication will never be
self and so no Constraint attached to a Stereotype will be evaluated.

Answering to Vlad's question I will present an excerpt of my UML Profile metamodel:

index.php/fa/12933/0/

For instance, if the user defines a Class XisInteractionCompositeElement with compositeElementType == 'List', it can only be composed of XisActionElements with actionElementType == 'ListItem'.
Is it possible to define such a constraint?

Thanks.

HI

I think you may have misunderstood 'Profile'; your example is not a
profile and has no user-defined stereotypes, so you are only using
ordinary constraints.

Hi Ed,

Probably I wasn't clear.
What I've presented above is the metamodel (where the UML metaclasses were omitted) and not a model that applies my Profile.
XisInteractionSpace, XisWidget, XisInteractionCompositeElement and so on, are indeed stereotypes that can be applied to classes.
XisOperation is a stereotype that can be applied to operations, while XisArgument can be applied to arguments of a XisOperation.

Hi Andre,

This looks interesting.

1. What tool are you currently using ?

2. Can you provide a diagram showing the relationship between the stereotypes and UML meta-classes ?

3. Can you provide the source of the profile ?

Regards
Vlad

I'm using Papyrus, but I've used Enterprise Architect to model the previous excerpt of the profile.

Here is what I've done so far:

index.php/fa/12962/0/

3. Can you provide the source of the profile ?

Yes, I can provide you my Papyrus Project.

Quote:

For instance, if the user defines a Class XisInteractionCompositeElement with compositeElementType == 'List', it can only be composed of XisActionElements with actionElementType == 'ListItem'.
Is it possible to define such a constraint?

Can you please give some feedback about this?

Thank you!

Hello!

Vlad, can you please answer my question?
Is it possible to validate a model that uses my profile?

Thank you!

Hi Andre,

It is interesting that you are extending UML for this purpose.
I guess one major advantage is that you get a diagram editor with a small effort.

Well, as Camille stated here, Papyrus does not support this feature yet.
Also, as Ed said here, an EMFV-based solution would not work either at the moment.

Looking at your meta-model it seems like a quite heavy extenstion to UML.
You might consider defining your own stand-alone metamodel by using EMF/Ecore.
But in that would mean that you cannot use the Papyrus UML diagram editor for your models.
You could get a working editor for your language by using Graphiti.
But I haven't tried it myself.

You could find some ideas in the Eclipse DSL book (rather outdated).

Maybe somebody else has some better recommendations.

Best wishes
Vlad

Hi

It depends how close to the bleeding edge you like to be.

June: Kepler
End of next week: M5
Now: Latest Papyrus N-build, and MDT/OCL build from
https://hudson.eclipse.org/hudson/job/buckminster-mdt-ocl-branch-tests/
(might be an I-build tomorrow)

Realistically, I recommend that you wait for M5, and then report any
problems that you find so that may be fixed for M6.

OCL entry for profiles appears to work; see picture on my recent OCL
newsgroup posting.

Diagram validation using profile OCL is active work in progress; it
might be working but it probably isn't.

Hi Ed,

Is it now possible (with the release of M5) to perform such a validation?

Thanks.

Hi

To be honest I haven't tried recently; I've been working on a scoping
bug for direct use of base_xxx and extension_xxx at M1.

In principle, you just need to enable the Profile constraints in the
Window->Preferences->Model Validation window (they won't appear till
you've validated once) then Validate again.
