Entity definition

IfcDatasetInformation captures "metadata" of an external dataset. The actual content of the dataset is not defined in this specification; instead, it can be found following the Location attribute.

The same IfcDatasetInformation can be referenced from the exchange structure in total or in parts (e.g. by refering to particular chapters or paragraphs) using the IfcDatasetReference. All IfcDatasetReference's that utilize the IfcDatasetInformation are accessible by the inverse relationship HasDatasetReferences.
