[QVTO] Loading non-registered metamodels [message #73629] Mon, 28 January 2008 17:28 Go to next message

Hello,

I've been using Operational QTV for a few days, and I think itŽs awesome.
I have tried it with some metamodels included in the EMF registry that
have been registered by the platform, but I havenŽt been able to use my
own metamodels (defined using ecore). For example, when writing:

modeltype WAP uses 'http:///schemas/MyMetamodel/_N7z_oM21EdyT85bEj1lqOw/0';

I get that the model can't be recognized. How can I register the metamodel
for QVTO to be recognized?

Thank you so much.

-Juan

Hi Juan,

By default, you get access to metamodels in the global registry
EPackage.Registry.INSTANCE.
For writing QVT against your ecore files located in the workspace, go to
properties of
the QVTO project. In the page 'QVT Settings/Metamodel mappings' you can
map your
metamodel package uri to a resource location uri, platform:/resource/....,
your ecore file.

So far, we have implemented only this simplistic mapping to address
dynamic metamodels as we believe
a more sophisticated solution is out of the scope of QVTO itself and we
expect this to be solved
by other Eclipse components; we will just make use of it.

Does this satisfy your usecase? Perhaps, we should do more ;-)

Regards,
/Radek

Richard and Radek,

Thank you so much for your help on my previous question! I successfully
had the metamodel recognized.

I would like to ask for help on one more thing. I am interested in
carrying out some transformations between UML models, taking as input an
UML marked model, i.e. a class diagram with stereotypes. However, these
marks over the origin model are serialized outside the containing package
of the input model, like this:

<xmi ...>
<uml:Package ...>
<class id="1" ... />
<class id="2" ... />
<class id="3" ... />
</uml:Package ...?
<MyProfile:MyStereotype base_Class="1">
<MyProfile:MyStereotype base_Class="2">
</xmi>

My mission here is to retrieve only the classes marked with MyStereotype.
To do this, I have to load both the UML and the MyProfile metamodels,
which is no problem. The deal comes when I want to get the actual marks
contained in my model, because the main mapping declares that I receive a
<uml:Package> as input, but this leaves the marks outside. I tried adding
an additional "in" argument at the main mapping signature, like this:

main(in pim: UML::Package, in marks: Set(MyProfile::MyStereotype), out
psm: UML::Package)

but the Run Configuration won't let me add a second input model (which
would be the same file).

Do you have any ideas on how to accomplish my mission? Thank you so much
again!

-Juan

Hi,

Minor addition on using non-registered metamodels. You can explicitly
refer to your workspace metamodel in modeltype expression as platfrom
resource:

modeltype WAP uses 'platform:/resource/.../mm.ecore';

Sergey

Hi Juan,

Current implementation considers only first object in given xmi file. It
means that whenever whole model file is supplied as [in] parameter in
Run UI it's equivalent to reference to models' first root object, i.e.
'../in.ecore' is equal to '../in.ecore#0'.
Of course given root object in Run UI can be referenced using it's id
(like ../in.ecore#1) and provided as separate [in] object but it's not
suited for unlimited number of objects.

In your case I'd suggest to:
- use UML profiles for the stereotype like markers
- use separate model for markers, all object should be rooted in some
container (like Package)

Regards,
Sergey

Hi Juan,

According to sample model you've mentioned interpretation of [in] models
specified in Run UI was changed. Now all root objects from the specified
URI are considered.
So it's possible to select model with marker as the only input. For
obtaining root objects from it the following code can be used:

inModel.rootObjects()->select(oclIsKindOf(uml::Package))
inModel.rootObjects()->select(oclIsKindOf(MyProfile::MyStereotype))


Regards,
Sergey

WOW, simply amazing. This is precisely what I needed, since moving the
marks to another package wouldnŽt work. Can I do check out from your
repository or should I wait for the next milestone release?

Hi Juan,

At present described feature is only available in sources from Eclispe
CVS HEAD. Checking out from it is Ok.

Regards,
Sergey.
