ifcOWL

Five OWL ontologies are maintained in this location for the Industry Foundation Classes (IFC) schema in EXPRESS. For each ontology, an RDF serialisation (OWL, RDF) and a Turtle (TTL) serialisation is made available. These ontology files are identical to the ontology files maintained at https://ifcowl.openbimstandards.org/ and https://www.buildingsmart-tech.org/ifcOWL/.

More information about ifcOWL can be found in: Pieter Pauwels and Walter Terkaj (2016). EXPRESS to OWL for construction industry: towards a recommendable and usable ifcOWL ontology. Automation in Construction 63 (March 2016) pp. 100–133. DOI:10.1016/j.autcon.2015.12.003.
