Figure 105 — Dataset Association
The concept Dataset Association describes how objects or object types can have associated datasets indicating external machine readable files. Datasets may be referenced in their entirety or as subsets using a Filter which depends on the dataset type. Contents within datasets may be referenced from any object.
Typical document meta data, such as format, issue date, editor, and similar, can be captured with the association, the dataset content however remains with the external files.
Figure 105 illustrates an instance diagram.
