RDB2OWL: A Language for Database to OWL Mapping and its Implementation
Guntars Būmans, Kārlis Čerāns · Baltic Journal of Modern Computing · 2019
Most data in industry still resides in relational databases (RDB) but Semantic web uses standard RDF and OWL formats.We consider a previously developed mapping language RDB2OWL allowing compact and end-user readable mapping specification.We describe the RDB2OWL implementation by translation into R2RML standard language that avoids the view rowset multiplication due to several 1-to-n relations from a single class in the ontology.
