multecore-logo-color-125x125MultEcore is a metamodelling tool which brings together the best of the worlds of fixed-level and multilevel metamodelling approaches.

MultEcore’s main plugin is a model editor based in EMF and Sirius, and combines the tool support, modelling ecosystem and low learning curve of EMF with the unlimited number of abstraction levels, potencies and flexible typing of multilevel metamodelling.

A second tool allows for the specification of Multilevel Coupled Model Transformations that exploit the multilevel capabilities of the framework, and performs a proliferation process to generate two-level rules that can be used in traditional engines for model transformation.

MultEcore is developed in the ICT Engineering Department of the Western Norway University of Applied Sciences. It has also been used in a joint work with University of Lübeck and a joint work with Universidad Autónoma de Madrid, which led to the creation of a tool for MLM rearchitecting and MLM tool exchange, available in Github.
