Many thanks for your note. I found the UML2.xsd in the source packaged.

 

Do you have UML XMI Spec? Although XSD does not deal with multi-inheritance, normally XMI is able to deal with. If I have a UML2 XMI Spec I could use it to transform my enterprise artificats to UML 2. Using EMF, I could genereate a 1st cut of the UML2 XMI Spec, however, the issue of multiple inheritance is still there.

 

Another questions:

 

How can I genereate the XSD for the whole project instead of package by package?

One of my packages is called entity. When EMF generates the xsd it created the file EntityXMI.xsd. However, in the head of the xsd file EMF puts the name of package (without XMI) as the schema location. How can I indicate to EMF to create correct schemalocation file names?

 

<xsd:import namespace="http:///www.unisys.com/EA/entity.ecore" schemaLocation="entity.xsd"/>

celio,

The XMI schema for UML2 is included in the model folder of the org.eclipse.uml2 plug-in (UML2XMI.xsd). As you've discovered, the schema isn't really all that useful since things like multiple inheritance, which aren't supported in XSD, will throw off most off-the shelf validators...

Cheers,

Subject	[uml2-dev] UML XML Schema

how can I get the UML XML Schema which is used in EMF?

Also, when I genereate the XML XMI Schema from EMF, the multiple inheritance
is not captured.
For instance, suppose a class A which is a subclass of B and C. Using EMF
"Generate Schema" from <<project>>.genmodel, where <<project>> is the name
of my project, I will get a schema similar to that one:

<xsd:complexType name="A">
                                 <xsd:complexContent>
                                                  <xsd:extension base="B"/>
                                 </xsd:complexContent>
</xsd:complexType>

but, no relationship will be generated to Class C. I know XML Schema does
not support multiple inheritance. However, UML 2 do use multiinheritance to
define UML 2 metal model. How does it done?

celio
