Officialisation of Linked Data Working Group

Linked Data Working Group >The Linked Data Working Group is responsible for building and maintaining a recommended version of an ifcOWL ontology as an equivalent to the IFC EXPRESS schema. The ifcOWL ontology is to be used in linked data and semantic web applications that consume IFC data.

Fit in BuildingSMART activities

Purpose:Bring together experts in BIM and Web of Data technologies to define existing and future use cases and requirements for linked data based applications across the building life cycle.
