Abstract:
The conceptual modelling of software architectures is of central
importance for the quality of a software system. A rich modelling
language is required to integrate the different aspects of architecture
modelling, such as architectural styles, structural and behavioural modelling,
into a coherent framework.We propose an ontological approach for
architectural style modelling based on description logic as an abstract,
meta-level modelling instrument. Architectural styles are often neglected
in software architectures. We introduce a framework for style definition
and style combination. The link between quality requirements and conceptual
modelling of architectural styles is investigated. The application
of the ontological framework in the form of an integration into existing
architectural description notations such as ACME and UML-based
approaches, and also service ontologies is illustrated.
