This is the repository for managing the buildingSMART ifcOWL ontology. Ontology files are made available in RDF and TTL syntax for the following IFC schema's:
- IFC2X3_Final: http://ifcowl.openbimstandards.org/IFC2X3_Final# (OWL, RDF, TTL)
- IFC2X3_TC1: http://ifcowl.openbimstandards.org/IFC2X3_TC1# (OWL, RDF, TTL)
- IFC4: http://ifcowl.openbimstandards.org/IFC4# (OWL, RDF, TTL)
- IFC4_ADD1: http://ifcowl.openbimstandards.org/IFC4_ADD1# (OWL, RDF, TTL)
- IFC4_ADD2: http://ifcowl.openbimstandards.org/IFC4_ADD2# (OWL, RDF, TTL)
These ontologies were generated using the software available at https://github.com/pipauwel/EXPRESStoOWL.
