On the other hand, I am not sure I grok when I would use a fetched

some such?
Think of how you might represent a smart playlists in iTunes. You
could use a fetch request in place of a fetched property, but this
requires a different (and "explicit") code structure -- that is,
you'll have to retrieve the fetch request from the model then
execute it.
'Kay. That makes a lot of sense. I am currently building fetch
requests on the fly in code, and I am not that happy with that
design. The first one to move to a fetched property, I think, will
be my 'worlds matching a criterion' code.
Thanks,
