Reading general XMI file [message #478613]

Hi,

I'm new the subject of parsing an XMI file with the eclipse libraries.
I've read the "EMF Framework Programmer's Guide" and "Getting Started
with UML2" in the UML2 wiki. I also googled a lot, but I could not find
the right information on how my problem is solved or even an indication
if it can be solved.

I have a XMI file that has nothing to do with EMF/Ecore. The file
contains a metamodel, unlike most guides (which seem only to work with
concrete datamodels in their xmi files). This metamodel can for instance
be a class diagram exported from IBM's Rational Rose or Visual Paradigm.
I want to write an application that reads the classifiers and their
associations from this XMI file. I believe it has to be possible to
transform the metamodel to some Ecore object-set that can be browsed in
Java. Am I correct?

If so, how should I configure a ResourceSet to load the XMI file in this
way? I tried using the UMLPackage.eINSTANCE in my code but with no
succes, because I don't seem to understand the core concepts of
ResourceSets and how I might configure them to load any XMI file. There
seem to be an overwhelming amount of settings for Resouces that are to
my knowledge not covered in some tutorial.

Ideas? Sample source code would be highly appreciated :-)

Regards,
Tom

Hi Tom,

I think this may be more of an EMF question regarding how to work with
ResourceSets you may want to try to post there for a more complete response.

One issue you will face will be to properly register packages with your
resource set.
Something like:
Map packageRegistry = resourceSet.getPackageRegistry();
packageRegistry.put(UMLPackage.eNS_URI, UMLPackage.eINSTANCE);

You will also probably need to register extensions:
Map extensionFactoryMap =
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( );
extensionFactoryMap.put(UMLResource.FILE_EXTENION,
UMLResource.Factory.INSTANCE);

The UML project also makes uses of pathmaps so you will need something like:
URIConverter.URI_MAP.put(URI.create(UMLResource.LIBRARIES_PA THMP),
umlResourcePluginURI.appendSegment("libraries").appendSegment( ""));

I would recommend downloading the UML2 examples and plugins and see how it
makes use of extensions.
There is also some example code here (scroll toward the bottom):
http://www.eclipse.org/modeling/mdt/uml2/docs/guides/UML2_2. 0_Migration_Guide/guide.html

The EMF newsgroup also has many Q/A regarding ResourceSets.

Cheers,
- James.

Thanks James. I will try your code suggestions and maybe also look at
the other newsgroup you suggested.

Hi,

I'm having trouble finding the source code of the examples (for UML2
3.0.0). I googled for org.eclipse.uml2.examples.source, but I don't seem
to find the source code of the examples. Where have you placed the
source code ? :)

Thank you.

Regards,
Tom

The source code is now jar'd up.
Download the UML2 SDK and then look for those .jars with a .source prefix
(ie. org.eclipse.uml2.examples.uml.ui.source_3.0.0xxx)
Cheers,
- James.

Thanks James. The file
org.eclipse.uml2.examples.uml.ui.source_3.0.0.v200905041045. jar contains
Java files, but org.eclipse.uml2.examples.source_3.0.0.v200905041045.jar
doesn't. Maybe the first one will contain enough information on how to
set up the ResourceSet.
