Abstract Like any software artifacts, metamodels are evolving entities that constantly change over time for different reasons. Changing by keeping them consistent with other existing artifacts is an error-prone and tedious activity without the availability of automated support. In this paper, we foster adoption metamodel refactorings collected in a curated catalog. The Edelta framework proposed...

Nowadays models, rather than code, become the key artifacts of software development. Consequently, this raises the level of requirements for modeling languages on which modeling practitioners should rely in their work. A minor inconsistency of a modeling language metamodel may cause major problems in the language applications; thus with the model driven systems development the solidness of mode...

In this paper we present a MOF compliant metamodel and UML profile for the Semantic Web Rule Language (SWRL) that integrates with our previous work on a metamodel and UML profile for OWL DL. Based on this metamodel and profile, UML tools can be used for visual modeling of rule-extended ontologies.

This paper describes a generic framework facilitating the specification and construction of component-based distributed systems. The framework integrates methods for specification of systems with tools supporting the construction of those systems. This is achieved by defining a reference architecture supported by a metamodel, a Component Modelling Language and tools for code-generation. The met...

the need for more comparisons among models is widely recognized. this study aimed to compare three different modelling approaches for their capability to simulate and predict trends and patterns of winter wheat yield in western germany. the three modelling approaches included an empirical model, a process-based model (lintul2), and a metamodel derived from the process-based model. the models ou...
