Supplier Request States

• PENDING - Hold placed, waiting for confirmation

• PLACED - Hold placed - we know the ID of the hold and the item

Fallback States

Context - see Slack

Broadly speaking, that will likely be something like:

• Available -> AVAILABLE

• Checked out -> CHECKED_OUT

• Unknown -> UNKNOWN

• Everything else to UNAVAILABLE

• No status (which shouldn’t happen) to Unknown

There are some quirky statuses that folks might want different mappings for:

• On order

• In process (because of the presence of In process (non-requestable) which implies the other kind of in process allows requests)

• In transit (which is ambiguous because we don’t know why it’s in transit)

• Intellectual item  (because I don’t know what that means)
