Ontology-based Use Cases for Design-time and Runtime Composition of Mobile Services

This paper presents application of ontology-based modelling and reasoning related to the different phases of the lifecycle of mobile services. Ontology-based descriptions complement traditional design-time and runtime models allowing more complex reasoning. We present use cases for ontologies that may be applied at design time, deployment time and/or runtime. Some important characteristics of our approach are: 1. ontological descriptions define complex artefacts that are built from simpler ones defined in an ontology; 2. a single ontology can be used for specifying various artefacts and for reasoning on various aspects at different phases of the service lifecycle; 3. an artefact can be used for various purposes. This paper provides examples of ontological descriptions along with use cases, and discusses the applicability of the approach.
