Shortcut for subpackages? [message #1064905]

Hello, I have a very basic question: is it possible, in a QVTO script, to define 'shortcut' names for subpackages? I'm writing a transformation but I end up with very long names, like

CIM::IEC61968::AssetInfo::PowerTransformerInfo
CIM::IEC61970::Topology::TopologicalNode

This produces some very bad-looking code.

Thanks a lot!

Hi

Suddenly had an idea. The basic ModelType syntax is

modeltype UML uses SimpleUml ("http://omg.qvt-examples.SimpleUml");

Have you tried using a fragment URI such as

modeltype AssetInfo uses AssetInfo ("...CIM#/IEC61968/AssetInfo");

EMF should share the multiple loads of ...CIM
so QVTo should recognize that
CIM::IEC61968::AssetInfo::PowerTransformerInfo and
AssetInfo::PowerTransformerInfo are the same type. But it might be safer
to use a different spelling for the alias.

(You can find the correct spelling of the fragment in any serialized XMI
reference to the target).

Regards

Hi, thanks for your reply!
It works, with this syntax:

modeltype AssetInfo uses "http: //iec.ch/TC57/2010/CIM-schema-cim15#AssetInfo";

I then have to define a new metamodel mapping in the project settings:

Source model URI:
http: //iec.ch/TC57/2010/CIM-schema-cim15#AssetInfo

Target model URI:
platform:/resource/atlantide2cim.bundle/models/cim15.ecore#//IEC61968/AssetInfo

I don't know if there is another syntax avoiding the metamodel mapping stuff...

Thanks again,
Daniele Pala

Hi

It looks as if fragment URIs are not well supported by the modelType
syntax. Please raise a Bugzilla.

Since your http: //iec.ch/TC57/2010/CIM-schema-cim15#AssetInfo is a
fudge rather actually a fragment identifier, I recommend using some
other character such as ~ to avoid confusing some unfortunate maintainer
later.
