How to get the platform uri from a pathmap? [message #523000]

In another conversation I got the CrossReferencer recommended. So I get
all external references of an EObject with

EcoreUtil.ExternalCrossReferencer.find(referee);

The keys of the returned map represent the EObjects of the referencing
model in the other resource. I want to collect all resources which
reference the EObject 'referee' and are placed in the platform:

Map<EObject, Collection<Setting>> references =
EcoreUtil.ExternalCrossReferencer.find(referee);
for (EObject referer : references.keySet()) {
Resource resource = referer.eResource();
URI uri = resource.getURI();
String platformString = uri.toPlatformString(true);
if(platformString != null){
referers.add(platformString);
}
}

But I never get a platformString because the uri always is a pathmap.
How can I now translate the pathmap to a platform string? And where can
I read more about pathmaps?

best regards,
Gilbert

There's URI.isPlatformResource.

Sounds like a UML2 thing... You can use
resourceSet.getURIConverter().normalize(uri) to follow redirections to
their ultimate resolution...

Thanks Ed - that was the crucial hint.
