How to get diagram information from XMI2.1 file exported by Enterprise Architect [message #871471]

I've got model information from xmi2.1 file exported by EA successfully.
But when I want to get diagram information from the xmi2.1 file,
I can only get extensionMap(EObject,AnyType),
and no idea how to get the diagram from the extensionMap.
should I analyse the extensionMap by myself?

anybody can help me? Thanks!

	public static void main(String[] args) {
		ResourceSet resourceSet = createResourceSet();
		URI uri = URI.createURI("er.xmi");
		Package model = UML2Util.load(resourceSet, uri, UMLPackage.Literals.PACKAGE);

		//try to get diagram and notation information
		XMIResource res = (XMIResource) resourceSet.getResource(uri, true);
		Map<EObject, AnyType> extensionMap = res.getEObjectToExtensionMap();
		
        }

er.xmi contains extension like below:

<xmi:Extension extender="Enterprise Architect" extenderID="6.5">
  <elements></elements>
  <connectors></connectors>
  <primitivetypes></primitivetypes>
  <profiles/>
  <diagrams></diagrams>
</xmi:Extension>

I tried to anylyse and parse the AnyTypeImpl of the EA extension information.
It seems OK but a little complex.

Hi

I've no idea what you're really asking.

In my experience, AnyTypeImpl's are often unresolved proxies, so far
from OK.

Diagram Interchange is not supported between UML tools. UML 2.5 will
introduce a UML DI model.

Since DI is based on GMF Notation, and Papyrus uses GMF Notation, it may
not be too hard for Papyrus to support the eventual UML 2.5 DI.

Ed,

AnyTypeImpl's are generally used to represent unrecognized content
(something that couldn't be matched to a model), or things like XMI
extensions for which there is no corresponding model). They're not
likely to be proxies; object of the feature's expected type with a proxy
URI will appear for that...

Hi Ed

I'm not sure what you mean. The original message had a follow on message
containing:

"When I load the xmi file, it seems it didn't dealt Integer as EClass
(general of EA "int").
org.eclipse.emf.ecore.resource.Resource$IOWrappedException: Value
mailto:'org.eclipse.emf.ecore.xml.type.impl.AnyTypeImpl@5c0662

(instanceClassName: null) (abstract: false, interface: false))' is not
legal.
at
org.eclipse.emf.ecore.xmi.impl.XMLLoadImpl.handleErrors(XMLLoadImpl.java:83)"

which is what I call an unresolved proxy. Is my terminology incorrect?

Regards

Ed

Ed, 
 
I see code like this that's dealing with extensions. 
 
<pre wrap=""> //try to get diagram and notation information
XMIResource res = (XMIResource) resourceSet.getResource(uri, true);
Map<EObject, AnyType> extensionMap = res.getEObjectToExtensionMap();

And XMI the looks like this:

<xmi:Extension extender="Enterprise Architect" extenderID="6.5">
<elements></elements>
<connectors></connectors>
<primitivetypes></primitivetypes>
<profiles/>
<diagrams></diagrams>
</xmi:Extension>
</pre>
 
This article is useful for understanding how AnyType is analogous to
DOM Element.

Hi Ed and Ed ^-^,

Yes, I want to get notation information of the XMI2.1 file exported by EA.
and such information exists in xmi.extension. When i load with my standalone code, it creates ModelImp for the root uml model, and AnyTypeImpl for the xmi.extension.

It seems I need to parse mixed and anyAttribute of the AnyTypeImpl to get the notation information. I did like this and it seems it's OK but a little complex.

Thanks again for your kindly help, and best regards!

Hallo jy zhang.

Did you manage to get a "readable" modelstructure?
I also tried to read and process an xmi2.1 file from EA, but as everything seemed to be AnyType I couldn't access (not even parse or cast) the elements.

We're now trying to read the file via SAX parser and an xmi-transformation similar to XSLT, but if it works with EMF that would be better I think.

I'd be happy about an answer on this old thread Wink

Hi

You are unlikely to get an answer on this old thread since it was far
from clear what the problem was. I certainly dismiss it as a user
problem not a tool problem.

If you have a problem provide a repro.

Regards
