Coral : A Metamodel Kernel for Transformation Engines

A metamodel kernel is a program library or application framework that is used to manage models described in user-defined modelling languages. Metamodel kernels provide the basic functionality to create models, add, delete and update elements in an existing models and to store and retrieve models from a XMI document. Coral is a metamodel kernel that is used to try in practice new research ideas in modelling technology. In this short paper, we describe Coral, our own implementation of a modelling tool and some discoveries related to modelling and metamodelling that we have found.
