Since data integration is a first-order priority in systems biology, metamodeling that is the foundation for data integration, should become an effective strategy among current approaches. In practice, the building of a metamodel requires four levels: the information level 1 or data level, which consists in the basic facts to integrate, the data model at level 2, i. e. how the data are organize...

We present a metamodel for modeling control and data flows on subclass scales in object-oriented systems. UML Profiles were used as a representation mean and a complete metamodel definition was provided with an example of a diagram application.

Based on experience from applying the Common Warehouse Metamodel to metadata management at a large Swiss bank, the applicability of metadata reference models in complex application domains is analyzed. In order to explain the context of the case, the state-of-the-art of the Common Warehouse Metamodel and its application for data warehouse management are summarized. Based on the project experien...

Today’s evolution of Ubiquitous Computing and Service Oriented Computing is leading to the development of ContextAware Services. However, the ambiguity of the context concept and the multiplicity of services’ execution contexts make CASs hard to build and show why there is a lack of generic approaches for designing such services. In this paper, we first present our context metamodel based on a ...

Metamodel evolution is becoming an inevitable part of software projects that use domain-specific modeling. Domainspecific modeling languages (DSMLs) evolve more frequently than traditional programming languages, resulting in a large number of invalid instance models that are no longer compliant with the metamodel. The key to addressing this problem is to provide a solution that focuses on the s...

100 words): Domain-specific modeling (DSM) assists subject matter experts in describing the essential characteristics of a problem in their domain. When a metamodel is lost, repositories of domain models can become orphaned from their defining metamodel. Within the purview of model-driven engineering, the ability to recover the design knowledge in a repository of legacy models is needed. In thi...

Security is among the most successful applications of aspectoriented concepts. In particular, in role-based access control, aspects capture access conditions in a quite modular way. The question we address in this paper is how can aspects be generated from access control policies under a validated process? We present a metamodel-based transformation from SecureUML, a rolebased access control la...

Previous research has provided metadata models that enable the capturing of the static components of a Data Warehouse (DW) architecture, along with information on different quality factors over these components. This paper complements this work with the modeling of the dynamic parts of the DW, i.e., with a metamodel for DW operational processes. The proposed metamodel is capable of modeling com...

This paper presents a metamodel that addresses the long standing gap between technical and sociotechnical views of IT-reliant systems in organizations. The metamodel provides an integrated set of concepts that extend and clarify the work system framework and related work system concepts, thereby helping in understanding, analyzing, and designing technical and sociotechnical systems. The metamod...
