Hi all,

1. What is it about?
The Framework for Model-independent Differences is based on EMF Compare and transforms emfdiffs to self-contained differences which can be used without the original models.
One example is creating a Patch for models - similar to what we know for text/code.
Tested so far: Ecore models, simple UML models, some domain specific EMF models.

2. Status
The first beta release has just been published. Downloads, tutorial, screencasts, and further documentation at:
http://modeldiff.imm.dtu.dk

3. Epatch vs. Model-independent Differences
Epatch is going to be part of EMF Compare as a patching mechanism.
Although both Epatches and Model-independent Differences are self-contained difference representations, they differ at least in the following points:
- Epatches describe differences exactly (and only) for the models the patch was created for whereas Model-independent Differences are more flexible and, with the use of OCL, are applicable even though the model has changed in the meanwhile.
- Epatches + Metapatches are also able to handle changes in the meta model, model-independent differences don't.
- The Model-independent Differencing Framework is a modular framework allowing different strategies for model element referencing (e.g. id- and condition-based), difference calculation, difference application, and conflict resolution.

4. Feedback wanted
If you experience any problems with our framework, if you miss some feature, or if you find the tool useful and just want to give general feedback:
please write comments on our website or contact us directly using the "Contact us" form.


Thank you for your attention, may our work be helpful for you :-)
Patrick

Hi Patrick,

That sounds very interesting. Can you point me to the licensing
information on your web page?

Hi Eike,

You're right, I missed all the license information.
It will be the GPL, I'll add that as soon as possible, hopefully this week.

Best regards and thanks for your interest!

Thank you Eike for pointing that out.

Patrick,

Now that sounds promising :). I've got a few questions on this :

1) You have a "compare and create model-independant differences" menu.
Have you taken a look at supporting the same through the Team => create
patch... menu (I don't know if it's feasible, but hey, that'd be nice ^^)?
2) EMF Compare allows comparison of whole resource sets (multiple models
with links between them, models splitted within multiple resources,
....). Do you support multiple resources patches?
3) Would you support say, comparing two versions of a metamodel,
creating the diff file, then applying the changes on instances of that
metamodel?

Sounds reasonable, we'll have a look at that.

Not yet.
It is not our primary goal to support multiple resources (yet), and we don't have any resources for that at the moment.
Still, it is an important issue and I would like to see that feature in the future.


> 3) Would you support say, comparing two versions of a metamodel,

Nope.
Afaik there are at least two approaches dealing with that:
http://www.uni-koblenz-landau.de/koblenz/fb4/institute/ueber greifend/sre/conferences/wsr/wsr2009/eyshold.pdf
http://www2.computer.org/portal/web/csdl/doi/10.1109/CVSM.20 09.5071722

In the long run, it would of course be nice to have..


Best regards
Patrick

Patrick,

Thanks for the answers, I was kind of expecting 3) to be 'no' :p. Edapt
(currently, COPE) is planned to answer this need, but a basic migration
through patches would have been nice ^^.

Hi all,

we had some compatibility issues with the latest version of EMF Compare 1.0.1, because ReferenceOrderChanges were not recognized by our tool.
The bug is fixed now and a new Release is available at http://modeldiff.imm.dtu.dk (note that we kept the major version 1.0.1 to adapt the version number of EMF Compare).

Cheers
Patrick

Hi Laurent,

Sounds reasonable, we'll have a look at that.

Not yet.
It is not our primary goal to support multiple resources (yet), and we don't have any resources for that at the moment.
Still, it is an important issue and I would like to see that feature in the future.

Nope.
Afaik there are at least two approaches dealing with that:

http://www2.computer.org/portal/web/csdl/doi/10.1109/CVSM.20 09.5071722

In the long run, it would of course be nice to have..


Best regards
Patrick

Patrick,

Thanks for the answers, I was kind of expecting 3) to be 'no' :p. Edapt
(currently, COPE) is planned to answer this need, but a basic migration
through patches would have been nice ^^.

Cheers!

Hi all,

we had some compatibility issues with the latest version of EMF Compare 1.0.1, because ReferenceOrderChanges were not recognized by our tool.
The bug is fixed now and a new Release is available at http://modeldiff.imm.dtu.dk (note that we kept the major version 1.0.1 to adapt the version number of EMF Compare).

Cheers
Patrick
