Towards a project centric metadata model and lifecycle for ontology mapping governance

Ontology matching and mapping is concerned with discovering correspondences between two ontologies to create a mapping that enable applications to relate, interlink or integrate data. The construction of such mappings is not trivial as they are created to serve a purpose and result from collaboration between the different stakeholders. Current ontology-mapping metadata formats only capture a glimpse of the mapping construction process by focusing on the exchange of mappings and they provide some limited properties to facilitate reuse and discovery. For mapping governance to be possible, we argue that a suitable metadata model -- which will be presented in this paper -- needs to capture all aspects from the ontology mapping lifecycle: from the inception of a project to the execution of these mappings. This allows one to formulate queries that not only would facilitate the discovery and reuse, but also queries that allow one to govern the ontology mapping projects and render the construction processes more transparent and traceable.
