Quoting "Ziso, Ya'aqov" <[email protected]>:
Karen Coyle,
By ‘create entities’ (below) is it NECESSARY to create records (and
keep them up-to-date), or is it possible/preferable to create them
on the fly?
./Ya’aqov
the display is created on the fly. the entities need to be somehow
embodied as entities in the database. 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...

.... It would be ideal to have an actual entity for each of the FRBR
1, 2 and 3 entities. We could even create entities that aren't
exactly in FRBR, such as for publication dates, publishers,
languages. And the main view is not of a single entity, but an
entity in relation to other entities. What's nearby? What happens
when I combine these two? (Also see WorldCat Identities as an
example of data that can be shown in relation to a person entity.)
