Workspace: An item that is under submission and active edit by yourself.

Workflow: An item that is under review for quality control and policy compliance.

Withdrawn : It is the removal of an Item from the archive. However, a withdrawn item may optionally be restored to the archive at a later date. A withdrawn item disappears from DSpace and the item appears to be deleted.

Non-discoverable: A non-discoverable (or "private") item is one that is simply hidden from all search/browse/OAI results, and is therefore only accessible via direct link (or bookmark).

Archived: An item that is in a stable state, available in the repository under the defined Authorization Policies.

Embargo: a special case of Archived/Published Item. The item has some time based access policy attached to it and/or the underlying bitstreams. Specifically, read permission for someone starting from a defined date.
