Generating an Excerpt of a Service Level Agreement from a Formal Definition of Non-Functional Aspects Using OWL

Mariam Rady (Johannes Kepler University Linz, Austria)

Abstract: If we take a look at current cloud computing services, the only quality guarantee they provide are vague Service Level Agreements(SLA). In this paper we modelled some non-functional aspects in an ontology and used this ontology as a knowledge base to generate an excerpt from a service contract. We concentrate in this excerpt on availability as it is one of the most discussed attributes in current Service Level Agreements.

Keywords: OWL, QoS, SLA, contracting, non-functional aspects, ontology
