 The metadata-deposit
 ====================
 
 Goal
 ----
 A client wishes to deposit only metadata about an 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 or several objects in the archive.
 
 Requirements
 ------------
 The scope of the meta-deposit is different than the
 sparse-deposit. While a sparse-deposit creates a revision with referenced
 directories and content files, the metadata-deposit references one of the
 following:
 
 - origin
 - snapshot
 - revision
 - release
 
 
 A complete metadata example
 ---------------------------
 The reference element is included in the metadata xml atomEntry under the
 swh namespace:

 Examples by target type
 ^^^^^^^^^^^^^^^^^^^^^^^
 Reference an origin:
 
 .. code:: xml
 
   <swh:deposit>
     <swh:reference>
       <swh:origin url="https://github.com/user/repo"/>
     </swh:reference>
   </swh:deposit>
 
 
 Reference a snapshot, revision or release:
 
 .. code:: xml
 
   With ${type} in {snp (snapshot), rev (revision), rel (release) }:
   <swh:deposit>
     <swh:reference>
       <swh:object id="swh:1:${type}:aaaaaaaaaaaaaa..."/>
     </swh:reference>
   </swh:deposit>
 
 
 
 Loading procedure
 ------------------
 
 In this case, the metadata-deposit will be injected as a metadata entry at the
 appropriate level (origin_metadata, revision_metadata, etc.) with the information
 about the contributor of the deposit. Contrary to the complete and sparse
 deposit, there will be no object creation.
