Using metamodels to keep source code information is one of the current trends in refactoring tools. This representation makes possible to detect refactoring opportunities, and to execute refactorings on metamodel instances. This paper describes an approach to language independent reuse in metamodel based refactoring detection and execution. We use an experimental metamodel, MOON, and analyze th...

Domain-specific modeling (DSM) assists subject matter experts in describing the essential characteristics of a problem in their domain. Various software artifacts can be generated from the defined models, including source code, design documentation, and simulation scripts. The typical approach to DSM involves the construction of a metamodel, from which instances are defined that represent speci...

We investigate quantile estimation by multi–element generalized Polynomial Chaos (gPC) metamodel where the exact numerical model is approximated by complementary metamodels in overlapping domains that mimic the model’s exact response. The gPC metamodel is constructed by the non–intrusive stochastic spectral projection approach and function evaluation on the gPC metamodel can be considered as es...

Process modelling initiatives generally develop their process models without much emphasis on data, burying their sequence of operations as a thread within a non-elementary process. More often than not, these buried operations are elementary atomic reusable components. The resulting models are generally not flexible or sufficiently reusable, suffering from update anomalies and redundancies. Add...

ion by conceptualization Abstraction by conceptualization strives to structure a given description of an information system in several layers that constitute a metamodeling architecture. Many modeling environments refer to the OMG’s metamodeling architecture [UML, 2000], depicted in Figure 4, which goes beyond the twolayer description of databases by proposing four layers: instance, model, meta...

We present a metamodel-based approach for specifying uml notations for domain-specific modeling languages. Traditionally, domain specific languages are either defined by uml profiles or using metamodels. We provide a generic integration of these two methods supporting arbitrary uml profiles and metamodels. Our approach provides a bidirectional mapping between the uml notation and the metamodel ...

The KF metamodel [Keet and Fillottrani, 2013, Keet and Fillottrani, 2014] is a comprehensive unifying metamodel covering the static structural entities and constraints of UML Class Diagrams (v2.4.1), ER, EER, ORM, and ORM2, and intended to boost interoperability of common conceptual data modelling languages. It was originally designed in UML with textual constraints, and in this report we prese...

Nowadays organizations need to improve their efficiency mainly due to the current economic situation. Several organizations are involved in process improvement initiatives in order to become more competitive in the market. These initiatives require processes definition and performance measurement activities. This paper describes briefly a metamodel integration between metrics metamodel and soft...

In requirements engineering, there are several approaches for requirements modeling such as goal-oriented, aspect-driven, and system requirements modeling. In practice, companies often customize a given approach to their specific needs. Thus, we seek a solution that allows customization in a systematic way. In this paper, we propose a metamodel for requirements models (called core metamodel) an...

In model-driven engineering (MDE), the unified modeling language (UML) 2.0 metamodel solution includes a that defines concepts and user model how are represented. UML 2.0, an important usage of is to ensure consistency between different diagrams in model. However, most existing metamodels lack integrated semantic framework project each diagram as view metamodel. To overcome shortcomings current...
