In Norway the IFC-format is approved as a national archive format for BIM-models.
This approval leads to requirement for a strict format versioning regime.
For a typical IFC-file the format version is given like this (from Archicad):
But we need to know if it is IFC 184.108.40.206, IFC 220.127.116.11, IFC 18.104.22.168 or IFC 4.3.rc.1 e.g.
Is the requirement for writing the FULL format version into the IFC-file missing in the IFC-standard or is it just neglected by the software vendors?
