FRBR Relations **
Context
When creating a data-model where many objects will be of the same work, (see [:GuidelinesForNewDatamodel/PatternLanguage/Audio Collection/Clasical Music:Clasical Music]) the use of the FRBR model can aid the planning of object relations at the levels between the collection (see [:GuidelinesForNewDatamodel/PatternLanguage/Collections In General:Collections In General]) and the file-object (see [:GuidelinesForNewDatamodel/PatternLanguage/File-Objects:file-objects]).
Description of pattern
When there is a multitude, especially of Expressions, Manifestations and Item's, of the work it can be very prudent to include a relation in the data-model to reflect this
Problem description
There are certain types of item groups within the library where there are many representations of the same work, take for instance the 7th symphony by Beethoven, an attempt to illustrate this form of construction is shown below.

A Manifestation can have several fedora file-objects, for instance recordings from [:http://en.wikipedia.org/wiki/Phonograph_cylinder: Phonograph cylinders] have been digitized in 3 versions since the original playback speed is unknown.
