Here’s a bit more background for the 2006 FRBR Challenge, in case it comes in handy. This diagram (it’s a link to a larger version, 73 KB PNG) puts three diagrams from the FRBR Report into one: it shows the Group 1, Group 2, and Group 3 entities, and the basic relationships between them.
- Group 1 entities: work, expression, manifestation, item
- Group 2 entites: person, family (added from FRAR), corporate body
- Group 3 entities: concept, object, event, place
In entity-relationship diagrams the lines indicate where relationships are, and a dashed-line box around a bunch of entities means that the relationship can be with any of the entities inside. So here, a work could be about a person and a corporate body (a biography of Henry Ford and Ford Motors), or about an event and a place (the signing of the Magna Carta and Runnymede), or about a person and a place (any book about someone living somewhere for a year), or an item and an event and a person and a person and a place (Frodo and Sam throwing the Ring into Mount Doom), etc. Mix and match as you need.
The Group 2 entities can be creators and owners and producers of works. If Moreland (person) composes (creates) a symphony (work), and Jenkins (person) publishes (produces) the score (expression) in print (manifestation), and the Warminster Symphony Orchestra (corporate body) performs (realizes) the symphony, and Donners-Brebner Music puts out (produces) a CD (manifestation) of it, and Anne (person) buys (owns) a copy (item) of it to give to her sister Peggy (person) for Christmas (event), then you can see how lots of entities can all relate.
Don’t worry, there won’t be a test. This may come in handy, though.
