Tutorial
The following presents a step-by-step guide to the functionalities of Echo.
Model consistency management consists of the consistency checking and recovering of the consistency between models and their metamodels. A model can be tracked by Echo by right-clicking in a XMI resource, and selecting Echo > Track model.
Once tracked, Echo automatically tests the consistency every time the resource is updated. When an inconsistency is detected, Echo flags the model as inconsistent and creates error markers over it.
The markers show up in the Problems view, where the user can then choose to repair that model by right-clicking Quick fix.
Echo provides two alternative distances to fixe the model: graph edit distance or an operation-based distance.
