Semantic data exchange ontology

Semantic enhancement of existing metadata schemas for data documentation and exchange is presented, to cover the fundamental concepts needed within the DOME4.0 project. Concepts from the DCAT RDF vocabulary (and from the RDF schema which DCAT depends on) for the description of datasets and data services (and catalogues) have been mapped in an enriched semantic framework provided by the Elementary Multiperspective Material Ontology (EMMO). This is done by imposing constraints that enable the usage of the original DCAT concepts into an OWL 2 DL framework. A mapping ontology from DCAT together with an ontology extension of the EMMO in order to deal with specific data concepts is provided in a public repository. Results of this mapping will be ported into the OntoCommons Top Reference Ontology. This will make it usable also by other ontological approaches (e.g. BFO, DOLCE). This work offers innovative value via (i) providing the means to bridge between the state of the art widely used top level ontologies and widely used web standard metadata schemas/vocabularies; and (ii) presenting a novel means of ontologising such metadata schemas and bringing them to a high-level semantic logic. A first example of combination of syntactic description of data and semantic mapping, is also provided.
