The transformation driven architecture (TDA) is a system building (in particular, tool building) approach that is based on model transformations, interface metamodels with corresponding engines, and event/command mechanism. This paper describes a metamodel and the corresponding engine for graph diagram presentations within TDA. The facilities of the metamodel and the engine include static diagr...

Moreover, I claim that:  the framework should include a metamodel and the means to implement whatever sociotechnical systems are modeled and embed these systems in an environment that supports its operation.  the metamodel and the supporting environment may be understood as (electronic or artificial) institutions.  the sociotecnical systems may be understood as normative multiagent systems ...

This article presents a tool that has been developed for the creation of multiple views of system requirements specification. The key component for developing the tool is a metamodel that enables to represent the different views, each one based on a particular method and technique. The primary benefits of the tool include: using two or more techniques in a system’s specification; translating re...

The 1997 OPEN process metamodel was the first fully documented software engineering process architecture for object-oriented projects, predating the Catalysis method, Select Perspective and the still emerging Rational Unified Process by a number of years. The OPEN process metamodel is based on a three-tier architecture, in which process Activities are broken down into a number of distinct Tasks...

A UML based metamodel for Bunge-Wand-Weber (BWW) ontology is presented. BWW ontology is a generic framework for analysis and conceptualization of real world objects. It includes categories that can be applied to analyze and classify objects found in an information system. In the context of BWW ontology, the metamodel is a representation of the ontological categories and relationships among them...

Analysis of dependencies between information systems, business processes, and strategic goals is an important part of the discipline of Enterprise Architecture (EA). However, EA models typically provide only visual and qualitative decision support. This paper shows how EA frameworks for dependency analysis can be extended into the realm of quantitative methods by the use of techniques from Faul...

Spatially distributed modelling has recently been introduced in pesticide registration procedures and policy evaluations. The assessments are quite demanding with respect to computational efforts, which probably is the reason that little attention has been paid so far to uncertainty analyses of leaching concentrations at the regional scale. Recently, a metamodel of pesticide leaching was develo...
