Hi Mahsa,
To perform pattern matching on an ETL transformation using EPL, you would first need to load the transformation in memory under an object that implements Epsilon's IModel interface (see the EMC chapter of the Epsilon book). Unfortunately, there's no built-in support for this at the moment so the short answer is that this is not possible unless you're happy to develop your own ETL-specific implementation of IModel (in which case, I'd be more than happy to help).
Cheers,
Dimitris

Hi Mahsa,
This is quite a big task. You'd need to define an Ecore metamodel for ETL and then write a Java program that parses ETL programs using EtlModule and then transforms the EtlModule's AST (getAst()) into a model conforming to your metamodel.
Cheers,
Dimitris

Hi my dear friend,
I want to use two meta-model in pattern checking. In other word, I have one meta-model and models that I check my pattern on these, but in my pattern, I need to load another meta-model. What is your suggestion? Can I define input parameters in EPL and declare second meta-model as input parameter?or should I use EOL for pre/post processing and use the Interoperability of EPL and EOL for calculating the final result?
Thank you for your help.
