8.6.3.3 IfcDocumentInformation

8.6.3.3.1 Semantic definition

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 referring to particular chapters or paragraphs) using the IfcDocumentReference. All IfcDocumentReference's that utilize the IfcDocumentInformation are accessible by the inverse relationship HasDocumentReferences.
