Hello,

Currently, i want to reference an object from UML by its qualifiedName (from an eProxy). The prupose of this need is to load UML elements from an eProxy containing their qualifiedName and only use the 'resolve' method.

I tried this for an attribute type and for a stereotype. This works fine for the stereotype but not for the attribute type as following (this works fine for both with their xmiid reference):

<?xml version="1.0" encoding="UTF-8"?>
<xmi:XMI xmi:version="20131001" xmlns:RootElement="schemas/RootElement/_LGC7ED9xEeagOoaTDa23Ww/0" xsi:schemaLocation="schemas/RootElement/_LGC7ED9xEeagOoaTDa23Ww/0 ../project/testProfile.profile.uml#_LGF-YT9xEeagOoaTDa23Ww">
  <uml:Model xmi:id="_Xz2I4D38EeaHCOjtpwqX8A" name="RootElement">
    <packagedElement xmi:type="uml:Class" xmi:id="_wPMdcD38EeaHCOjtpwqX8A" name="Class1">
      <ownedAttribute xmi:type="uml:Property" xmi:id="_sqOcYD9xEeagOoaTDa23Ww" name="Attribute1">
        <type xmi:type="uml:Class" href="../project/testType.uml#//RootElement/Type1"/>
      </ownedAttribute>
    </packagedElement>
    <profileApplication xmi:type="uml:ProfileApplication" xmi:id="_AY3mgEG9EeaRt-jEcozggA">
      <eAnnotations xmi:type="ecore:EAnnotation" xmi:id="_AY8fAEG9EeaRt-jEcozggA">
        <references xmi:type="ecore:EPackage" href="../project/testProfile.profile.uml#_LGF-YT9xEeagOoaTDa23Ww"/>
      </eAnnotations>
      <appliedProfile xmi:type="uml:Profile" href="../project/testProfile.profile.uml#//RootElement/Stereotype1"/>
    </profileApplication>
  </uml:Model>
  <RootElement:Stereotype1 xmi:id="_CIRuoEG9EeaRt-jEcozggA" base_Class="_wPMdcD38EeaHCOjtpwqX8A"/>
</xmi:XMI>

As stipulated in the code, the references to attribute type must be '../project/testType.uml#//RootElement/Type1' and the stereotype ''../project/testProfile.profile.uml#//RootElement/Stereotype1'.

Did i make a mistake in my example ? Or maybe another way is better to reference my UML elements ?

Thanks in advance for your helpful.

Best regards,
Nicolas

Hi, Nicolas,

UML resources use UUIDs as the xmi:id, and the xmi:id as the URI
fragment. So, you cannot reference a model element using its qalified
name as the URI fragment. You must use the XMI ID. See, for example,
how this works in the href of the <references> element in the
annotation of the profile application.

Your application of the 'Stereotype1' stereotype on the class loads
because of the xmlns:RootElement namespace declaration, not because of
the profile application which is actually broken: you appear to be
trying to reference a stereotype as the applied profile, and that by
its qualified name, which as per above will not work.

HTH,

Christian
