Hello

I ran into a problem while writing a Java program which uses ATL to make a transformation to UML.

Here is the content of a transformation result:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xmi:XMI xmi:version="2.0" xmlns:xmi="http//www.omg.org/XMI" xmlns:xsi="http//www.w3.org/2001/XMLSchema-instance" xmlns:uml="http//www.eclipse.org/uml2/3.0.0/UML">
  <uml:Model name="pattern">
    <packagedElement xsi:type="uml:Package" name="interfaces">
      <packagedElement xsi:type="uml:Interface" name="if1">
        <ownedOperation name="op1"/>
      </packagedElement>
      <packagedElement xsi:type="uml:Interface" name="if2">
        <ownedOperation name="op2"/>
      </packagedElement>
      <packagedElement xsi:type="uml:Interface" name="if3">
        <ownedOperation name="op3"/>
      </packagedElement>
    </packagedElement>
  </uml:Model>
  <uml:Class name="test" clientDependency="/1/@interfaceRealization.0 /1/@interfaceRealization.1 /1/@interfaceRealization.2">
    <interfaceRealization supplier="/0/interfaces/if1" client="/1" contract="/0/interfaces/if1"/>
    <interfaceRealization supplier="/0/interfaces/if2" client="/1" contract="/0/interfaces/if2"/>
    <interfaceRealization supplier="/0/interfaces/if3" client="/1" contract="/0/interfaces/if3"/>
  </uml:Class>
</xmi:XMI>

The references to model elements are made using a notation that looks like XPath but I want to use the xmi:id attribute.
I can generate them inside of eclipse by checking the "Output model content types detection" setting as shown by the following excerpt:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xmi:XMI xmi:version="2.1" xmlns:xmi="http//schema.omg.org/spec/XMI/2.1" xmlns:uml="http//www.eclipse.org/uml2/3.0.0/UML">
  <uml:Model xmi:id="_1ddgQNWZEeGTCKqszs1QrQ" name="pattern">
    <packagedElement xmi:type="uml:Package" xmi:id="_1ddgQdWZEeGTCKqszs1QrQ" name="interfaces">
      <packagedElement xmi:type="uml:Interface" xmi:id="_1ddgQtWZEeGTCKqszs1QrQ" name="if1">
        <ownedOperation xmi:id="_1ddgQ9WZEeGTCKqszs1QrQ" name="op1"/>
      </packagedElement>
      <packagedElement xmi:type="uml:Interface" xmi:id="_1ddgRNWZEeGTCKqszs1QrQ" name="if2">
        <ownedOperation xmi:id="_1ddgRdWZEeGTCKqszs1QrQ" name="op2"/>
      </packagedElement>
      <packagedElement xmi:type="uml:Interface" xmi:id="_1ddgRtWZEeGTCKqszs1QrQ" name="if3">
        <ownedOperation xmi:id="_1ddgR9WZEeGTCKqszs1QrQ" name="op3"/>
      </packagedElement>
    </packagedElement>
  </uml:Model>
  <uml:Class xmi:id="_1deHUNWZEeGTCKqszs1QrQ" name="test" clientDependency="_1deHUdWZEeGTCKqszs1QrQ _1deHUtWZEeGTCKqszs1QrQ _1deHU9WZEeGTCKqszs1QrQ">
    <interfaceRealization xmi:id="_1deHUdWZEeGTCKqszs1QrQ" supplier="_1ddgQtWZEeGTCKqszs1QrQ" client="_1deHUNWZEeGTCKqszs1QrQ" contract="_1ddgQtWZEeGTCKqszs1QrQ"/>
    <interfaceRealization xmi:id="_1deHUtWZEeGTCKqszs1QrQ" supplier="_1ddgRNWZEeGTCKqszs1QrQ" client="_1deHUNWZEeGTCKqszs1QrQ" contract="_1ddgRNWZEeGTCKqszs1QrQ"/>
    <interfaceRealization xmi:id="_1deHU9WZEeGTCKqszs1QrQ" supplier="_1ddgRtWZEeGTCKqszs1QrQ" client="_1deHUNWZEeGTCKqszs1QrQ" contract="_1ddgRtWZEeGTCKqszs1QrQ"/>
  </uml:Class>
</xmi:XMI>

However, I cannot find how to trigger this behaviour from an external program as setting the option "OPTION_CONTENT_TYPE" to true in the options of the launcher does not help.
Is there anyone here who might have an idea on how these xmi:id are generated ?

This isn't an ATL problem.
For serialization, ATL delegates to the corresponding resource factory.
This is done using the file extension.
Try to save the output file as a ".uml" file, this should give you what you want.
