[news.eclipse.modeling.gmt.amw] Re: view multiple models at once?

[Marcos Didonet Del Fabro <marcos.didonet-del-fabro@xxxxxxxxxxxxxx>]

Hello,

When you open a weaving model (*.amw), the editor is independent of any 
other weaving editors that are already opened, so the functionality you 
want is not natively supported. This is a typical behavior editors in 
Eclipse: to associate one file extension with an editor, and the editor 
opens one file at a time.

However, I can think of two alternatives to obtain the behavior you want. :)

First, you can extend the editor by adding a second weaving panel. But 
the editor will be specific to this case.

Second, you can extend the metamodel extension for traceability to weave 
three (3) models instead of two (2). You just need to create a new 
reference that points to WModelRef elements, and a three-way link that 
extends WLink.

The interface of AMW will adapt automatically to any number of woven models.

Then, to support the new traceability extension, you need to change the 
ATL2WTracer transformation. Now the trace will be between three models, 
not two.

Least, but not last, I guess you don't want to modify the ATL2WTracer 
transformation, because you want to add traceability only to 
transformations that take one model as input and that produce another 
model as output.

In this case, you should create a new transformation that takes the two 
traceability weaving models as input and that transforms them into a new 
traceability weaving model. The transformation will 'merge' the elements 
that have the same xmi:id in a three-way link. The output weaving model 
must conform to the traceability extension that supports weaving three 
models.


Regards,

Marcos.
