Hello,

I am using ETL for transforming the source model to target model. Both source

model and target models are using the same Ecore model. I have attached the use

case in the image Eplison_ETL_UseCase.png. The use case is very simple.

I have to write the transformation rule to move the ("C" Nodes and its children

Nodes) of parent "A" Node to "B" Node.

I am finding difficultly to writing these rules for movement of containers between

the Nodes, Basically I am filter the Node "C" during transformation of Node "A".

Later during transformation of Parent Node "B" I am quering all the Nodes"C" and

adding its to children. I guess the guard : conditions is not allowing to add the Node

"C" to Node B. If I introduce the new separate rule to copy only Node "C" and its

children. Then Node"A" and Node "C" and it children disappears.

I feel we can achieve this use case using simple transformation rules. I have

attached the minimal working example. Please unzip and run the

Tree2Tree.launch. The transformation rules are found in Tree2Tree.etl. Please let

me know if you need any further information.

Thank you for your support.

Best Regards,

Rajkumar

Hi,

How about doing a copy transformation and then moving the C nodes under B in a post{} section of the transformation?

Cheers,
Dimitris
