Conclusion

  • The development of a shared ontology enables interoperability between Common Core Ontologies (CCO) and OGC EDR.
  • The shared ontology takes into consideration various mappings between the two representations (CCO and EDR) by identifying BroaderThan, NarrowerThan, Similar, etc. relationships between the concepts in the two representations as well as the properties.
  • Subsequently the bridge concepts between them are identified and used in the alignment of the two representations by the shared ontology, which is developed in OWL.
  • A SHACL (Shape Constraint Language) shape is developed for validating RDF data against a set of constraints. To create a SHACL shape for the shared ontology, we define constraints for classes, properties, and individuals.
  • Finally, the usefulness of the developed shared ontology has been demonstrated in two use cases using SPARQL.
  • More advanced approaches can be explored and used for the development of shared ontology.
