The latest release candidate 3 of the upcoming IFC4 standard is now available. It can be accessed and downloaded from the official buildingSMART International specification website, at:
http://buildingsmart-tech.org/specifications/ifc-releases/ifc2x4-release/rc3-release
This release candidate marks an end of a long and intensive quality improvement work led by the Model Support Group of buildingSMART International focusing on compatibility, better documentation quality and on final specification enhancements.
The release candidate 3 of IFC4 (internal release name IFC2x4RC3) will be the basis of submitting the Draft International Standard ISO/DIS16739 to ISO for balloting. It is expected that the balloting will start in November and end in early summer 2012.
Further documentation enhancements and improvements of the property and quantity definitions are planned before the IFC4 final release will be published (earliest by late Summer 2012], also depending on the progress of achieving the full International Standard status for ISO16739.
The whole buildingSMART community is encouraged to participate in this last public review cycle before IFC4 final release and to submit any issues and recommendations for improvement using the IFC2x4 Review Issue database at http://buildingsmart-tech.org/jira/browse/IFR. The review period is scheduled to end on March 31, 2012.
