Is this possible with EMFCompare? [message #501524]

Hello All,

I want to compare 2 xmi files and make a delta(attributes added/deleted etc) of it.

Is it possible to use EMF Compare for this in standalone?

I checked the code from the CVS , but I only manage to get the match Model from it when I load 2 UML models? But I didn't manage to load only the 2 xmi's in it . I always get an exception.

What is exactly needed to compare 2 xmi's via EMF Compare ? Do I need to give up also the UML's or is it enough to give only the xmi's ?

Also in the standalone version there is some comment:
// Register additionnal packages here. For UML2 for instance :

But how can I do this for loading xmi , what is the code for this?

Also can I serialize the Diffmodel for example with eg JAXB ?Or how can I do this . I want to make Java object eg DiffModel from this delta?

Many thanks

Randi

EMF Compare is tested to be usable in standalone mode. Check out the
org.eclipse.emf.compare.example.standalone project from the CVS for an
example of how to do it.

Without the exception and its trace, can't say much. Though loading UML
models with xmi extension is somewhat of a bad idea; EMF detects the
file contains UML and does the necessary arrangements according to the
file extension. Not sure if this applies to standalone loading though.

I do not understand this. What is your xmi file if it is not your UML model?

look at the standalone example. How you serialize the model is you call;
be it through the standard EMF "Resource#save()" or some other mean.

EMF Compare is tested to be usable in standalone mode. Check out the
org.eclipse.emf.compare.example.standalone project from the CVS for an
example of how to do it.
==> I used the code from CVS in standalone version.But this was only to load models with the extensions*.uml. What I want to do is to load only 2 models with the extension*.xmi which I made with another Case Tool eg BOUML after exporting the UML model as an xmi.But I didn't succeed to load these xmi's.The code I used to load these xmi's is
//Code Start

// Create a resource set.
ResourceSet resourceSet = new ResourceSetImpl();
// Register the default resource factory -- only needed for stand-alone!
resourceSet.getResourceFactoryRegistry().getExtensionToFacto ryMap()
.put(Resource.Factory.Registry.DEFAULT_EXTENSION,
new XMIResourceFactoryImpl());
// Get the URI of the model file.
URI fileURI = URI.createFileURI(new File("T1.xmi")
.getAbsolutePath());
// Demand load the resource for this file.
Resource resource = resourceSet.getResource(fileURI, true);
// Print the contents of the resource to System.out.
try {
resource.save(System.out, Collections.EMPTY_MAP);
} catch (IOException e) {
}

//Code End

models with xmi extension is somewhat of a bad idea; EMF detects the
file contains UML and does the necessary arrangements according to the
file extension. Not sure if this applies to standalone loading though.
==> No I used only the xmi which I exported via another tool. So I made the model with a Case Tool ,after that I export it in xmi.

The exception I get is :

most external tools have an export to "EMF" instead of "xmi". Then
again, most external tool's export fail in one way or another : bad xml,
missing references, illegal IDs ... Can you open your exported model
with the "UML editor" within eclipse ("open with => UML editor" right
click menu)? If yes, can you validate it (right click on the root =>
"validate"? If either of these is "no" then your external modeler fails
at exporting the model properly.

Rename your "*.xmi" model as "*.uml". This can help as it tells EMF your
model is UML, and allows it to set up all the necessary actions for
loading UML models.

Randi,

Extension doesn't matter. what your "*.xmi" file contains is UML, that
is why renaming it to "*.uml" allows its loading from Eclipse as
expexted. That is also the reason why you must follow the instructions
of the UML2 wiki to load your file.

resourceSet.getResourceFactoryRegistry().getExtensionToFacto ryMap().put(Resource.Factory.Registry.DEFAULT_EXTENSION,
new XMIResourceFactoryImpl());

registers the XMIResourceFactory for all extensions, including your
"*.xmi" extension; and that is the contrary of what must be done. Your
line should look like

resourceSet.getResourceFactoryRegistry().getExtensionToFacto ryMap().put( "xmi",
UMLResource.Factory.INSTANCE);

So as to register the xmi extension with the UMLResourceFactory for your
resource set. And that will not be enough for standalone loading of your
files; the remaining steps oultined in
http://wiki.eclipse.org/MDT/UML2/FAQ#What.27s_required_to_lo ad_a_UML_.28.uml.29_resource_from_a_standalone_application.3 F
must be done as well : registering the libraries, metamodels and
profiles pathmaps, registering the UMLPackage instance in the registry...

As first mentionned, EMF Compare can compare any model loadable through
EMF. Yet without those steps, you will not be able to load your models,
let alone compare them.

most external tools have an export to "EMF" instead of "xmi". Then
again, most external tool's export fail in one way or another : bad xml,
missing references, illegal IDs ... Can you open your exported model
with the "UML editor" within eclipse ("open with => UML editor" right
click menu)? If yes, can you validate it (right click on the root =>
"validate"? If either of these is "no" then your external modeler fails
at exporting the model properly.

Rename your "*.xmi" model as "*.uml". This can help as it tells EMF your
model is UML, and allows it to set up all the necessary actions for
loading UML models.
