UML metamodel uses its own dataTypes. So HUTN cannot convert strings to the UML-defined String datatype.

This is the error I got:

[Line: 9, Column: 5, Reason: Expected String for: name, Line: 10, Column: 35, Reason: Expected String for: name, Line: 11, Column: 28, Reason: Expected String for: name]

BTW, why doesn’t http://www.eclipse.org/modeling/project-info/team.php have a nice photo of you and a biography? Please reopen https://bugs.eclipse.org/bugs/show_bug.cgi?id=182613 and provide some details about yourself.

I was under the impression that the UML2 tooling was an orthogonal modelling technology.

In fact, it is possible to use our HUTN tooling with the UML2 metamodel. Some example HUTN source:

@Spec {
  MetaModel "uml" {
    nsUri = "http://www.eclipse.org/uml2/2.1.0/UML"
  }
}

Packages {
  Package "Pk" {
    name: "package"
    nestedPackage: Profile "Pr" { name: "profile" }
    ownedType: Class "C" { name: "class" }
  }
}
