But the entity is, for example, the author, not that whole page of information. It's an identified "thing" in the database that can have relationships with other "things" -- which can then be brought into the display. You can see how OL has defined things by looking through the list of types: http://openlibrary.org/type Everything that we consider a "data element" is a type, and types can be created that contain other types (look at author as an example). This makes for a lot of flexibility, and in theory any type could be treated as an entity (although it doesn't make sense for all of them). I'm sure this is only one of many ways to do this... kc > > .... It would be ideal to have an actual entity for each of the FRBR > 1, 2 and 3 entities.
