| Dealing with large models, the ISO20022 case [message #1797700] |

Hi all,
I am trying to deal with large models. In particular, I want to process instances of the iso20022.ecore standard that can be found here.
https://www.iso20022.org/e_dictionary.page
the "eRepository.iso20022" instance of iso20022.ecore is very large.
My goal is to implement a model to text transformation using egx/egl pair.
I registered the iso20022.ecore metamodel in Eclipse. Then, when I try to set up a run configuration, I select the eRepository.iso20022 file and the Eclipse freezes in loading that large model.
How can I solve this issue? any parameter to set properly (in run configuration?).
thanks in advance!
Luca

Hi Luca,
We should really add an auto-detect metamodel option at some point that users can turn off in such cases. Until then, a workaround would be to type the path of the model in, as opposed to using the browse button, and add the respective metamodel URI manually.
Cheers,
Dimitris

Hi Dimitris,
thanks for your reply. I am adding the metamodel manually. Now, while playing with Epsilon, I am a bit confused by the available options for model types.
My input M1 artifact here is the *.iso20022 model, i.e., an instance of the M2 artifact iso20022.ecore.
What is the correct model type to use here among:
- EMF Model
- M0 EMF Model
- Registered EMF Package
- Virtual EMF Model
Probably I missed the examples for these options. Is the eRepository.iso20022 a M1 artifact that conforms to the M2 artifact iso20022.ecore? if yes, I cannot figure out what an M0 EMF artifact is.
cheers,
Luca

Hi all,
I solved the problem with the following workaround:
- I created a trivial model (.iso20022) that conforms to the given metamodel (iso20022.ecore),
- I created a run configuration using EMF Model as model types (it is obvious but when I have some troubles I doubt about any possible assumption :) ),
- I manually assigned the right metamodel to the selected model (this was the problematic step with very large model)
- I saved the launch configuration in a file
- I reopened the same run configuration and I replaced the dummy model with the real one (the eRepository.iso20022 provided by the ISO20022 official page)
- I run the model transformation (an EGX/EGL one in my case).
Hope it helps.
best,
Luca
