Hi,

How can I convert ETL constraints such as, "s.father.isDefined()" to its equivalent OCL constraint so that it can be used as a input of tools such as "EMFtoCSP".

Hi

EOL is inspired by OCL but makes some deliberate changes, most notably elimination of the -> collection navigation operator.

I am currently working on an ATL2QVTr transformation as a test harness for QVTr utility. It also requires an OCL to OCL sub-transformation but ATL-OCL is not deliberately different to OMG-OCL. Once this works ETL/EOL to OCL might be considered.

Today, I think your only alternative is manual transcription, unless you care to develop an automated approach.

Regards

Ed Willink

Thanks. I should get an automatic approach. I would prefer this tool was developed. However, I should write it myself.
I need some details about the difference between ETL constraints and OCL constraints. Would you please help me in this regard?

Hi

ETL is inspired by OCL. Therefore the ETL documentation should make the differences clear. Not my problem. Try the Epsilon documentation / newsgroup.
