More Group 1 relationships
For the same relationships expressed in a different way, and some new relationships, see what Ian Davis and Richard Newman did:
It’s all nicely and readably laid out.
Group 1 relationships
This is background information for the 2006 FRBR Challenge. It may serve as a useful reference. All the lists below are taken from the FRBR Report.
First of all, remember that the Group 1 entities are work, expression, manifestation, and item. Second, remember that a work is realized in an expression, an expression is embodied in a manifestation, and a manifestation is exemplified in an item. Those are the three basic relationships between the four Group 1 entities. To be clear on when two works are related or when something is an expression or manifestation of a given work, look at Barbara Tillett’s family of works diagram, which can be found on page four of the What is FRBR? (2.8 MB PDF) booklet she wrote for the Library of Congress. (If you want to be clear on FRBR in general, that’s a great place to start.)
These relationships can exist between works:
- successor: has a successor / is a successor to (for example, A has a successor B / B is a successor to A)
- supplement: has a supplement / supplements
- complement: has a complement / complements
- summary: has a summary / is a summary of
- adaptation: has an adaptation / is an adaptation of
- transformation: has a transformation / is a transformation of
- imitation: has an imitation / is an imitation of
- whole/part: has part / is part of
There can be these relationships between expressions:
- abridgement: has an abridgement / is an abridgement of
- revision: has a revision / is a revision of
- translation: has a translation / is a translation of
- arrangement (music): has an arrangement / is an arrangement of
- successor: has a successor / is a successor of
- supplement: has a supplement / supplements
- complement: has a complement / complements
- summarization: has a summary / is a summary of
- adaptation: has an adaptation / is an adaptation of
- transformation: has a transformation / is a transformation of
- imitation: has an imitation / is an imitation of
- whole/part: has part / is part of
These relationships can exist between an expression and a work:
- successor: has a successor / is a successor of
- supplement: has a supplement / supplements
- complement: has a complement / complements
- summarization: has a summary / is a summary of
- adaptation: has an adaptation / is an adaptation of
- transformation: has a transformation / is a transformation of
- imitation: has an imitation / is an imitation of
These relationships can exist between manifestations:
- reproduction: has a reproduction / is a reproduction of
- alternate: has an alternate / is an alternate of
- whole/part: has part / is part of
This relationship can exist between a manifestation and an item:
- reproduction: has reproduction / is a reproduction of
These relationships can exist between items:
- reconfiguration: has reconfiguration / is a reconfiguration of
- reproduction: has reproduction / is a reproduction of
- whole/part: has part / is part of
Some relationships depend on whether the two works in question are autonomous or referential. “A referential work is one that is so closely connected to the other work in the relationship that it has little value outside the context of that other work. An autonomous work is one that does not require reference to the other work in the relationship in order to be useful or understood” (FRBR Report section 5.3.1). For example, a referential work can complement a musical work if it’s a cadenza, libretto, or choreography; an autonomous work can complement another work if it’s incidental music (such as for a play) or it’s a musical setting of text.
See the full FRBR Report in PDF form for more details and examples. And remember that if you apply FRBR yourself, you can use whatever relationships you need. There’s no law saying you can only use the ones above. You can make up your own to serve your own purposes.
