I wish to use the 'hybrid' approach ETL for M2M transformation. My source and target meta-models are similar, and for much of the translation I could deep clone the source elements for use in the target. Is there a feature available that allows me to do this easily, without manually constructing a duplicate?

Hi Andy,

You can right-click on your .ecore file and select Epsilon->Generate
ETL. This will generate a copy ETL transformation which you can then
extend/modify.

Cheers,
Dimitris

Hi Dimitrios,

further to my recent post; it would appear that the transformation generated does not create deep clones. I'll explain why I would find deep cloning useful. In my transformation a source node (with its sub-tree) is used in more than one node in the target. The target nodes that use the source node require a copy of the original source node (and its sub-tree). Therefore I wish to have deep clones of a particular source node to insert into various target nodes.

Cheers, Andy
