- Full embargo: no access to either the metadata or bitstream of an item until embargo period ends. Items Even if a match existsItems do not appear in: search or results, browse results, even if a match exists; though RSS feeds, OAI-PMH feeds, etc. Though the metadata and bitstreams are stored, it's as if the item and its bitstreams had never been deposited, or indexed.
- Partial embargo: metadata visible, some/all bitstreams inaccessible. In this case, items appear in browse or search indexes so searchers and browsers know an item and its bitstreams exist. However, they can't download/view bitstreams. (This is the behavior of the current implementation.)
- Group access to embargoed items: embargoed items (full or partial) are viewable and all contents are completely accessible to members of select groups. This will address needs often expressed by archivists, who need a dark archive of materials in DSpace
