A commitment-based reference ontology for services.

The concept of “service” has been characterized in different disciplines and by different authors from various points of view. This variety of characterizations has emerged because although this notion seems intuitive, it is far from trivial, with many interrelated perspectives. Given their importance in enterprise computing and Service Science in general, we believe that a clear account of services and service-related concepts is necessary and would serve as a basis for communication, consensus and alignment among approaches and perspectives. In this paper we propose a commitment-based account of the notion of service captured in a core reference ontology called UFO-S. We address the commitments established between service providers and customers, and show how such commitments affect the service lifecycle. Moreover, we show that the commitment-based account can serve to harmonize different notions of service in the literature. [ABSTRACT FROM AUTHOR]
