Weaving model manually created [message #531976]

Hello!

My Source-Metamodel and Goal-Metamodel are completely different. So, it makes no sence to use the given transformations (such as name equality etc).
Is there any possibility to create a weaving model manually?
Just making links from MM1 to MM2 "per hand"?

And if yes - how to do that?

I hope, my question is understandable.

Thank you.

Alexey

Hi,

The matching transformations are used when the metamodels have some degree of explicit similarity, i.e., the name equality, typing, tree structure, etc.

You can create your links manually with the use interface. You should first select the appropriate metamodel extension, and create the links between the left and right elements. There are two extensions that you might use;

1) The extension from the metamodel comparison use case. You can create "ElementLink"s between classes, and "AttributeLink"s between attributes, references, and so on.

2) There is another simple extension that helps to create links targeted for generating ATL. You can find more information about this extension on the following link:
http://wiki.eclipse.org/index.php/AMW#Graphical_development_ of_ATL_transformations

Regards,

Marcos.

Hi, Marcos!

I tried the qatl and got an error by creating a WM:

org.eclipse.ui.ide.FileStoreEditorInput can not be cast to
org.eclipse.ui.IFileEditorInput

Could you please help me to solve it?

Thanx a lot!

Alexey

Hi.

I see it could be related to two issues:

- you do not have the good version of Eclipse (problem on the typecasting).

- is the file loaded from outside Eclipse?
