Hello,

I have a question and it would be great if someone can explain to me how I can do that.

I have a set of input models conforming to the same metamodel (metamodel A) and I want to transform them to a target model conforming to metamodel B. The transformation is not merging.

The issue is that number of instance models is unknown and it can vary so to solve this issue, I have a transformation that takes first model conforming to metamodel A as input and generate the output conforming to metamodel B; then I have another transformation that takes the generated output and the next input and generates the second output conforming to metamodel B. The second transformation is executed multiple time until all input models are considered.

I know this is not an efficient way of doing that. I read the article "On the Use of Higher-Order Model Transformations" by Massimo Tisi et al to understand what it is but I am not sure if it can help me and if yes, how I can do that, what is the input and what is the output for that,.... (are the inputs the metamodels A and B and the out put is the transformation?)
I appreciate a lot if any one can explain that to me. For implementing that, is there any manual that I can read about it?

Thanks in advance.

Higher-order transformations are useful if you want to manipulate transformation code in some way. The problem you describe seems more like some sort of workflow description problem, that cannot be handled by a simple ATL launch configuration.

Have you tried expressing your workflow as an Ant script using the ATL Ant tasks? Or perhaps tried MTCFlow?

Cheers,
Dennis
