[ATL] Generate href="pathmap://..." [message #656974]

Hello,

I'm using ATL to transform to target model UML. In detail, my question is about the generation of "href" in "importedElement".

I want to get the following structure:
<elementImport xmi:type="uml:ElementImport" xmi:id="_OpYhkTp_EeCSALIK68aV3A">
<importedElement xmi:type="uml:PrimitiveType" href=" pathmap://UML_LIBRARIES/UMLPrimitiveTypes.library.uml#Intege r"/>
</elementImport>

However until now, I can only get some structure like the following:
<elementImport xmi:type="uml:ElementImport" xmi:id="_s1Mh4kPgEeC51by4Fq16xw" importedElement="_s1Mh40PgEeC51by4Fq16xw"/>
<uml:PrimitiveType xmi:id="_s1Mh40PgEeC51by4Fq16xw"/>

It's not nested and there is also no "href". Here is the rules I've written:
elementImport_uml:SysML!"uml::ElementImport" (importedElement <- packageableElement_uml),
packageableElement_uml:SysML!"uml::PrimitiveType" ()

Please help me. I'm totally confused.

Thans in advance.
Kind regards,

Kirk

Hi Kirk,
Pathmaps are tricky to get right. See the following example....

rule AToModel {
from
s : MMA!A
to
t : UML!Model
(
packageImport <- pi
),
pi : UML!PackageImport
(
importedPackage <- UML!Model.allInstancesFrom('DATATYPES')->select(e|e.oclIsTypeOf(UML!Model))- >first()
)
}

This will ensure a custom UML Datatype library is imported and ready for use in an ATL transformation. You can of course alter it to use just some types from the UML Datatype library. Be sure to pass the UML Datatype library into your transformation as a model to be able todo this.

Regards,
Ronan
