Comment 1 for bug 827970

I think repub state 4 is traditionally meant to indicate a book has derived, as the change occurs after a derive task for all items.

I'm curious about why we use the scheme we do. We have, as you say:

-1 loaded but not scanned
-2 opened at scribe
3 at foldout station (deprecated)
4 post-upload, deriving now

Wouldn't it make more sense to have a scheme like:

0 - loaded, waiting for scanning
1 - opened at scribe for scanning
2 - scanned, waiting for repub
3 - repubed and uploaded, waiting for derive
4 - derived

Does this conflict with anything else in our operation, like microfilm?
