How to create .model files while doing model transformation using ETL

Question

I am doing a model transformation using Epsilon Transformation Language. I already have the meta models for the input and output models. I have written the transformation code and want to check if it works for a small hello-world application.So, I wrote a JUnit test.

I have a hello-world application written according to my input meta-model, and I also have the hello-world application that I am expecting from my transformation. However, in this link, http://www.eclipse.org/epsilon/cinema/ they have shown .model files for the input and output models. I have no clue as to how I can obtain .model files from my hello-world files. The file extension of my hello-world applications conform to their respective meta-model, for eg. hello-world.xml.

Please can someone tell me how to generate the .model files from any other file format?

Thank you so much.

For anyone who might face this issue in future, here is the solution, that I figured out myself. A .model file is basically an xml file. If in eclipse, you see it without using exceed editor, you can see the xml structure. If you try to manually create a dummy .model file and check the xml structure, you will understand how to make your own model files from the code of your hello world. Basically, you can write an application in java that extracts the necessary information from the code and generates an xml file.
