IFC Core : IFCx Architecture

IN DEVELOPMENT : subject to change. IFCx is not a released or ratified specification. It is developed in the public buildingSMART/IFC5-development repository, whose own examples are explicitly labelled "preliminary and will be updated." Every fact in this skill is a moving target. NEVER teach IFCx as a stable target and NEVER recommend it for a production exchange.

IFCx is the JSON data encoding of the IFC5 generation : the .ifcx file format and its ifcx.dev schema host. This skill explains what an .ifcx file is, how its composition graph works, and how IFCx relates to IFC5. It is the format-side counterpart to ifc-core-ifc5-architecture, which covers the IFC5 standard.
