CT Document reference Owner History

Since information captured during the process of design and construction can change over time, FMH-EM requires the use of IfcOwnerHistory to identify the company and date of the last change of each piece of FMH-EM required data. Software may use this information by comparing date-stamped data to show the progression of information captured as the project moves from design through construction and commissioning to handover.

As IFC has a different information mapping for links to document information, that mapping must be used. The initial suggestion for that mapping is:
ReferencedDocument.DocumentOwner.Name where DocumentOwner.is_a(“IfcOrganization”) or ReferencedDocument.DocumentOwner.TheOrganization.Name where DocumentOwner.is_a(“IfcPersonAndOrganization”)
Note: for IFC2X3, use:
ReferenceToDocument[0].DocumentOwner.Name where DocumentOwner.is_a(“IfcOrganization”) or ReferenceToDocument[0].DocumentOwner.TheOrganization.Name where DocumentOwner.is_a(“IfcPersonAndOrganization”)
ReferencedDocument.CreationTime Note: for IFC2X3, use: ReferenceToDocument[0].CreationTime
