Model Transformation Wiki

This wiki contains information about our purpose and transformation methods.

Why do we need transformation?

In a basic tree-based class hierarchy in Ecore file, it's sometimes confusing to view relations between classes and properties. If you think a massive class structure, it can be impossible to see. We wanted to visualize and transform that hierarchy to a graph to understand the structure better. Because, a graph is a very effective tool in presenting visual information.

How to Transform

In the begining of the process, we have a graph structure implemented in java and Ecore classes such as EClass, EAttribute, etc. You can see the complete class and inteface list.

Transformation process includes:

• EClass to vertex transformation
• EAttribute to vertex transformation
• EReference to edge transformation

While traversing the ecore file , we start to transforming EClasses first. After that, we follow the same procedure for sub-Ecore classes beneath that EClass. If we encounter a EReference, we convert it to an edge. If we encounter a EAttribute, we convert it to a vertex.
