Hello,

How should I define modeltype in the transformation to transform a java model in another?

I have a java model created from MoDisco discoverer.

I have noticed that only metamodels are defined in ModelType. I need transform models.

Regards.

Hi

Just look at the XMI of any model that QVTo or other equivalent tooling
loads and you'll see the MI namespace declarations that identify the
metamodel.

Ed,

the header of the XMI is

<?xml version="1.0" encoding="ASCII"?>
<java:Model xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:java="http://www.eclipse.org/MoDisco/Java/0.2.incubation/java" name="tesis">

Here is the information I need?

Regards.

I tried define the header file of the following way

modeltype A uses 'platform:/resource/tesis/tesis_java.xmi';

transformation Plus_To_Minus(in a : A, out A);

and i recieve the following error:

Failed to resolve metamodel 'platform:/resource/tesis/tesis_java.xmi'

Regards.

Hi

It is always easier to debug a problem if you have a similar example
that works.

You have an example project that does:

modeltype UML uses
'http://www.eclipse.org/qvt/1.0.0/Operational/examples/simpleuml';
....
transformation Simpleuml_To_Rdb(in uml : UML, out RDB);

and an example file that does:

<?xml version="1.0" encoding="UTF-8"?>
<uml:Model xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:uml="http://www.eclipse.org/qvt/1.0.0/Operational/examples/simpleuml"
name="model">

Comaprng these should help you understand why

modeltype A uses 'platform:/resource/tesis/tesis_java.xmi';

is not a good idea.

Regards

Hi Ed,

I have the Simpleuml_To_Rdb working but

modeltype UML uses
'http://www.eclipse.org/qvt/1.0.0/Operational/examples/simpleuml';

refers a ECORE file (metamodel), however i have a XMI file (model).

You understand me?

Regards.

Hi

When working with Java you have objects that conform to/instantiate
their classes.

When working with models you have models (containing a hierarchy of
instances) that conform to metamodels (containing a hierarchy of classes).

If you confuse meta-levels garbage and errors result.

http://www.eclipse.org/qvt/1.0.0/Operational/examples/simpleuml is the
nsURI of a metamodel.

platform:/resource/org.eclipse.m2m.qvt.oml.samples.simpleuml2rdb/pim.simpleuml
is a model

http://www.eclipse.org/MoDisco/Java/0.2.incubation/java is the nsURI of
Modisco's Java metamodel

platform:/resource/tesis/tesis_java.xmi is presumably your Java model.

Regards

The Simpleuml_To_Rdb example transform the UML metamodel in RDB metamodel. I need transform a model (xmi) created through java metamodel.

Regards.

No

The Simpleuml_To_Rdb example transforms an XMI file conforming to the
SimpleUML metamodel to an XMI file conforming to the RDB metamodel.

You want a transformation that transforms an XMI file conforming to the
Modisco Java metamodel to another XMI file conforming to the Modisco
Java metamodel.

Seeing the "Hello world" in Eclipse QVTo by Fabio Levi Siqueira clarify some concepts.

I understand now that, first the transformation is declared and then the source model is specified for the transformation execution.
