IfcDocumentInformation captures "metadata" of an external document. The actual content of the document is not defined in this specification; instead, it can be found following the Location attribute.
The same IfcDocumentInformation can be referenced from the exchange structure in total or in parts (e.g. by refering to particular chapters or paragraphs) using the IfcDocumentReference. All IfcDocumentReference's that utilize the IfcDocumentInformation are accessible by the inverse relationship HasDocumentReferences.
HISTORY New entity in IFC2x.
IFC4 CHANGE Attribute HasDocumentReferences changed to be inverse, attribute Location added, and attribute ElectronicFormat modified.
