Spatio-temporal reasoning in CIDOC CRM: an hybrid ontology with GeoSPARQL and OWL-Time

Semantic description of cultural heritage information is already widely structured through CIDOC
CRM and its different extensions. This shared understanding of cultural heritage information
has already proved its usefulness. Until now, despite its spatial and temporal data management
proposition, lack standardization limited the possibilities in terms of reasoning and workability.
This paper proposes to increase the potentiality offered by the current scheme by including
GeoSPARQL and OWL-Time in the framework. The result, as hybrid ontology, allows concurrent
spatial and temporal handling. These are used to provide a near-full data management for
complex spatio-temporal reasoning and querying through SPARQL queries. Example queries
depicting the strength of the approach and allowing knowledge discovery in huge archaeological
datasets illustrate its benefits
