Owner=user-id

    Specifies the owner of the tape volume set. The owner is the user
    who will be permitted to recover (roll forward) the database. The
    user-id parameter must be one of the following types of OpenVMS
    identifier:

    o  A user identification code (UIC) in [group-name,member-name]
       alphanumeric format

    o  A UIC in [group-number,member-number] numeric format

    o  A general identifier, such as SECRETARIES

    o  A system-defined identifier, such as DIALUP

    When used with tapes, the Owner qualifier applies to all
    continuation volumes. The Owner qualifier applies to the first
    volume only if the Rewind qualifier is also specified. If the
    Rewind qualifier is not specified, the optimization operation
    appends the file to a previously labeled tape, so the first
    volume can have a different protection than the continuation
    volumes.
