 The metadata-deposit
 ====================
 
 Goal
 ----
 A client wishes to deposit only metadata about an origin or object in the
 Software Heritage archive.
 
 The metadata-deposit is a special deposit where no content is
 provided and the data transferred to Software Heritage is only
 the metadata about an object in the archive.
 
 Requirements
 ------------
 The scope of the metadata-deposit is different than the
 sparse-deposit. While a sparse-deposit creates a revision with referenced
 directories and content files, the metadata-deposit references any of the
 following:
 
 - origin
 - snapshot
 - release
 - revision
 - directory
 - content
 
 
 A complete metadata example
 ---------------------------
 The reference element is included in the metadata xml atomEntry under the
 swh namespace:

       </swh:deposit>
   </entry>
 
 References
 ^^^^^^^^^^
 
 Origins
 =======
 
 The metadata may be on an origin, identified by the origin's URL:
 
 .. code:: xml
 
   <swh:deposit>
     <swh:reference>
       <swh:origin url="https://github.com/user/repo" />
     </swh:reference>
   </swh:deposit>
 
 Graph objects
 =============
 
 It may also reference an object in the `SWH graph <data-model>`: contents,
 directories, revisions, releases, and snapshots:
 
 .. code:: xml
 
   <swh:deposit>
     <swh:reference>
       <swh:object swhid="swh:1:xxx:aaaaaaaaaaaaaa..." />
     </swh:reference>
   </swh:deposit>
 
 The value of the ``swhid`` attribute must be a `SWHID <persistent-identifiers>`,
 with any context qualifiers in this list:
 
 * ``origin``
 * ``visit``
 * ``anchor``
 * ``path``
 
 and they should be provided whenever relevant, especially ``origin``.
 
 Other qualifiers are not allowed (for example, ``line`` isn't because SWH
 cannot store metadata at a finer level than entire contents).
 
 
 Loading procedure
 ------------------
 
 In this case, the metadata-deposit will be injected as a metadata entry of
 the relevant object, with the information about the contributor of the deposit.
 Contrary to the complete and sparse deposit, there will be no object creation.
