Abstract

Despite the ubiquity of services, there is still no consensus on
their exact nature and structure. This consensus, however, is
necessary to unambiguously describe and trade services
physically as well as in an Internet of Service. To make some
progress towards a shared conceptualization, we present in this
paper a general service model based on the DOLCE foundational
ontology. In our understanding, a service is essentially composed
of a service process whose core actions (delivered by a service
producer to a service consumer) comply with the exposed
description of a service provider’s commitment. Each service
belongs to a larger service system process which obeys legal and
pricing constraints. We illustrate the model’s usefulness and
relevance by the means of a continuous example.
