StreamIsReferencedOnDocument

Description

This modelling pattern allows to express that a stream is referenced on a document. No information about the type of reference is made - it could be symbolic, textual or both. It is assumed that, while parsing the information about the stream from a data file, an entity for the underlying document can be found or is created in a database that contains information about documents.

Definition

A stream (x1) is referenced on a document (x2).
