The AtlanMod MegaModel Management (AM3) prototype, being developed by the AtlanMod Team, is part of the MoDisco project. The AM3 project acts in this way by providing a practical support for modeling in the large, i.e. dealing with global resource management in a model-engineering environment. AM3 is part of the AMMA platform.


The goal of AM3 (AtlanMod MegaModel Management) is to provide a practical support for modeling in the large. The objective is to deal with global resource management in a model-engineering environment. We base this activity on the concept of a "megamodel". A megamodel is a terminal model in which all model engineering resources available in a given scope (a zone) are registered. AM3 assumes that tools for model transformation and model composition already exist and are available. The basic idea is that there is no unique metamodel for megamodels. Instead, the user may use metamodels from a library or invent their own ones. This means that the kind of artifacts stored in or retrieved from a given MDE repository may vary. We know some of these artifacts (models, metamodels, transformations, semantic correspondences, etc.) but many others may be contextually defined. This is one of the difficulties of the global model management: the AM3 tool is designed to be metamodel-agnostic in order to handle this contextual variability.

The totally new AM3 prototype is now available from the Eclipse-GMT AM3 SVN (see How Install New AM3 From SVN) (sources only).

Note that you can still download the previous version of the AM3 plugins (for ATL developers) by following the instructions provided from the "How Install Old AM3 Plugins From SVN" Wiki page (some documentation on the provided ATL-specific AM3 Ant Tasks is also available).
