Hi,

there are several ways of implementing constraints. 1) Gmfmap model, 2) OCLInEcore (http://wiki.eclipse.org/MDT/OCLinEcore), 3) Epsilon Validation Framework (http://www.eclipse.org/epsilon/doc/evl/). All of these have their pros and cons depending on what you want to achieve. In my project I did choose a mix of EVL for constraints and OCLInEcore for implementing methods as I wanted to have the whole stuff available from outside of GMF.

Hi

Thank you Ralph for reply

the simple one is the first, by using Audits container or just a simple constraint, according cases and the complexity of the project.
