Abstract:
Ontologies can be used to unambiguously describe the semantics of the entities of a domain. Furthermore, ontologies can also contain instances that represent states of real world systems. When an ontology is dynamically updated to reflect changes in the real world, or vice versa (reaction to new information added by a reasoner), data needs to be mapped in both directions. In many systems, this happens through an ad-hoc implementation. Maintaining translations in both directions can be complex and time-consuming. Also, it is often difficult to split a mapping into reusable components. In this paper we examine how lenses, an approach to the view update problem originating from database research, can be applied to value updates in ontologies. Lenses provide bi-directional composable translations from one model to another. The application of the approach in the domain of IT management, where an ontology is constantly updated with values from managed systems, is described as part of the ongoing project.
