Work – Expression – Manifestation
31 Jan 08
What follows is an exact textual reproduction of slide 9 (with notes) from the Powerpoint Presentation Relationships in FRBR, by Dr. Barbara B. Tillett (FRBR Workshop, Dublin, Ohio, May 2, 2005). Here’s a link to the entire PPT file. Tillett is (or at least was, in 2004 when she wrote this booklet [PDF]) Chief of the Library of Congress’s Cataloging Policy & Support Office, Chair of the IFLA Cataloguing Section, a member of the Joint Steering Committee for Revision of the AACR, and more!
Relationships – Work/Expression/Manifestation
w1 J.S. Bach’s Goldberg variations
e1 performance by Glen Gould in 1981
m1 recording released on 331/3 rpm sound disc in 1982 by CBS Records
m2 recording re-released on compact disc in 1993 by Sony
m3 digitization of the Sony re-release as MP3 in 2000
An expression then “is embodied in” a manifestation. Notice that we are showing here a musical performance. Music can be performed, but only when it is recorded do we have a manifestation.
Work 1 – J.S. Bach’s Goldberg variations. . . is realized by the expression – that is, the performance by Glen Gould, which in turn “is embodied in” at least these 3 manifestations:
m1 – the recording on a phonograph record
m2 – a re-release on a compact disc and
m3 – a digitization on an MP3 file.
Implicitly the manifestations of the same expression have a sibling relationship to each other – that may be an equivalent content.

Comments on "Work – Expression – Manifestation"
Hello!
In this example, I don’t think the expression is the actual performance – it would be the sound produced in this performance:
“Expression: The intellectual or artistic realization of a work in the form of alpha-numeric, musical, or choreographic notation, sound, etc., or any combination of such forms”.
It is quite tricky to put the performance at the same ontological level than the produced sound, because you might want to describe more complex “workflows” happening at the expression levels (performance using a recorded sample of another performance of a particular arrangement etc. etc.) – we tried to tackle these issues whilst staying in a FRBR framework in the music ontology community project (http://musicontology.com/) – please join the discussion!
Cheers!
