The clear definition of a metamodel can be considered helpful for any conceptual modeling approach, and the i* framework is not an exception. Agreeing on a metamodel for i* can be considered even more convenient than ever when we are aware of the different dialects and variations that the community proposed, and keep proposing, over the seminal i* definition. In this paper we present the revise...

Enterprise software systems are prevalent in many organisations, typically they are data-intensive and manage customer, sales, or other important data. When an enterprise system needs to be modernised or migrated (e.g. to the cloud) it is necessary to understand the structure of this data and how it is used. We have developed a toolsupported approach to model database structure, query patterns,...

This document is intended to establish a set of usage scenarios and goals to motivate development of the Ontology Definition Metamodel (ODM). The contents of the final version of this document will be incorporated in the ODM specification to provide context for its application and use.

A metamodel definition presents some important issues in the construction of an object database management system, whose rich data model inevitably increases the metamodel complexity. The required features of an object database metamodel are investigated. Roles of a metamodel in an objectoriented database management system are presented and compared to the proposal defined in the ODMG standard ...

This report presents a MOF-compliant metamodel for calculating software metrics and demonstrates how it is used to generate a metrics tool that calculates coupling and cohesion metrics. We also describe a systematic approach to the analysis of MOF-compliant metamodels and illustrate the approach using the presented metamodel. In this approach, we express the metamodel using UML and OCL and harn...

Metamodels are abstractions that are used to specify characteristics of models. Such metamodels are generally included in specifications or framework descriptions. A metamodel is for instance used to inform the generation of enterprise architecture content in the Open Group’s TOGAF 9 Content Metamodel description. However. the description of metamodels is usually done in an ad-hoc manner with c...

In consequence of changing requirements and technological progress, metamodels are subject to change. Manually migrating models to a new version of their corresponding metamodel is costly, tedious and error-prone. The coupled evolution of a metamodel and its models is a sequence of metamodel changes and their corresponding model migrations. These coupled changes are either metamodelspecific or ...

Modeling languages and thus their metamodels are subject to evolution [2]. When a metamodel is adapted, existing models may no longer conform to the adapted metamodel and thus need to be migrated. Model migration is a special case of exogenous model transformation [7], since original and adapted metamodel are usually different from each other. However, the metamodel versions also share some sim...
