Representation and traversal of large clabject models

Abstract

Multi-level modeling using so-called clabjects has been proposed as an alternative to UML for modeling domains that feature more than one classification level. In real-world applications, however, this modeling formalism has not yet become popular, because it is a challenge to efficiently represent large models, and providing fast access to all information spread across the meta-levels at the same time. In this paper we present the model representation concept that relies on a permanent condensed view of the model, the corresponding traversal algorithms, and their implementations that proved adequate for model-driven engineering of industrial automation systems consisting of hundreds of thousands of model elements. © 2009 Springer Berlin Heidelberg.
