org.eclipse.emf.search.ocl.targetMetaModel
Users wanting to contribute a target metamodel for OCL expression contextual evaluation should extends targetMetaModel.
targetMetaModel extension point requires three different atributes :
* nsURI - An EPackage nsURI according to the one set in .genmodel configuration file to generate the Java code of this Ecore package. * level - The modeling level which will be used for the contextual OCL expression evaluation. This level comes from the meta modeling levels commomly described in corresponding domain writtings (eg: M1 is an instance of a model, M2 a model, M3 the Ecore metamodel & M4 the EMOF). * target - There are currently only two targets : "Ecore" & "UML". This has to be extended to support arbitrary model target contributions.
