Web Technologies
Main principles distributed / decentralised information management interactive information search and reasoning over the web portals of partial data
Key potentials Interoperability Linking across domains Logical inference and proofs Kernel Content Level of Detail Pieter Pauwels, Sijie Zhang and Yong-Cheol Lee, Semantic web technologies in AEC industry: a literature review. Automation in Construction 73 (Jan.): 145-165 (2017).

Structure of IFC4 (2015) Industry Foundation Classes (IFC) by buildingSMART represents an open specification for Building Information Modeling (BIM) data that is exchanged and shared among the various participants in a building construction or facility management project. The specification consists of the data schema, represented as an EXPRESS schema specification (ISO 10303-11), and reference data represented as Step files (ISO 10303-21) or XML files.
