  -## Media collection [/media{?offset,count,filter,sort}]
  +## Media collection [/media{?offset,count,filter,sort,annotations}]
   Given the role of Media as mainly internal raw material means that it often makes more sense to use
   the Work Media collection instead of this one (see below).
   
  
positive.code: The various objects and their properties are documented in much more detail here:

  ## Media [/media/{mediaID}]
  A media instance, which is a read-only record of a particular media instance of a Work
  at the time it was recorded in the catalog.
  
  Media instances are intended to be the "raw material" of Works, so access to them
  may be restricted in the catalog to require a reference via a Work (see Work Media below).

negative.code: ### Update a Work [PUT]
  The following parameters can be updated, any others are ignored:
  
  - alias
  - description
  - public
  - collaborators
  - annotations (see below)
  - sources (only source_work)
  - media
      
  This really behaves like `PATCH`, so that any omitted parameters are not changed.
