Hi,
I need to make a transformation from BPMN to UML . Which program is best to do this project. Is topcased best for it. And is there a tutorial that could help me because I'm an absolute beginner in qvt programming.
thanks in advance

Hi

[I think Topcased is going obsolete with most of the good extra bits
contributed back to the main Eclipse projects.]

Most people learn QVTo from the New->Example...->QVTo->Simple UML to
RDBMS included in the distribution.

The QVT 1.3 specification revision drafting has just completed. You can
see many discussions at https://dev.eclipse.org/mhonarc/lists/qvto-dev/.

In particular the new specification draft is at
https://dev.eclipse.org/mhonarc/lists/qvto-dev/msg00383.html. It has an
additional 10 pages of introductory text explaining some of the more
important QVTo capabilities much more clearly; a few examples have been
debugged. Eclipse QVTo has a small amount of work to do to fully comply
with some of the clarifications.

Hi Srdjan

I wrote several simillar transformations by means of Eclipse + QVTo. Some of them we use in production environments. It works fine. Alternatively you can try ATL or Epsilon Transformation Language. But I preffer QVTo.

There are not too much tutorials. You can try these:
http://www.levysiqueira.com.br/2011/01/eclipse-qvto-hello-world/
http://reqpro.blogspot.ru/2013/01/qvt-transformations-with-eclipse.html

Also you can read the specification:
http://www.omg.org/spec/QVT/

I'm writing a series of articles about Model Driven Architecture. And I plan to write a QVTo tutorial two months later.

Thanks Denis,
I already read those tutorials.
this is my next problem:
My transformation has next content:
main()
{
bpm.rootObjects()[Definitions]->map defToModel();

}

mapping Definitions::defToModel() : Model
{

name := self.name;

packagedElement += bpm.objects()[Process]->map proToPack();

}

mapping Process::proToPack() : Package
{
name := self.name;
}

This only work if content of bpmn diagram in text file is:

<bpmn2:Definitions ... >

</bpmn2:Definitions>

if text file has more lines like <Process> and more, my transformation gives exception:

Invalid source URI 'platform:/resource/bpmn/process_1.bpmn' for parameter 'bpm'

Hi

"Invalid source URI 'platform:/resource/bpmn/process_1.bpmn' for
parameter 'bpm'

looks like a bad model. Check that you can validate in the Sample
Reflective Ecore EDitir.

I can't validate model if i create Generic BPMN 2.0 Diagram, but i can if create BPMN2 Model. If i create bpmn2 model then i can't change definitions to Definitions and that i need to do because qvto transformation recognize only Definitions (with uppercase)
