4.1.6 - The repository shall obtain sufficient control over the Digital Objects to preserve them.

Control in this context has two meanings:

  • Legal control of the Digital Objects, in terms of the rights to perform the necessary operations on them.
  • Physical control of the Digital Objects, or rather of the media on which the Digital Objects are stored.

Legal Control

The publisher grants the CLOCKSS archive the rights to:

  • Make and keep permanent copies of the Content Information and associated metadata on the boxes in the CLOCKSS PLN.
  • Disseminate the Content Information and metadata under Creative Commons licenses if the CLOCKSS Board decides that a trigger event has occurred.

These rights are signalled:

  • For harvest content, by the publisher placing a CLOCKSS permission statement in the agreed-upon place in their web site.
  • For file transfer content, by the publisher placing the SIP on the CLOCKSS FTP server, or on their own FTP server so as to be accessible to the CLOCKSS account.

Physical Control

As described in CLOCKSS: Ingest Pipeline, both harvest and file transfer content is initially staged during ingest processing on ingest machines operated by the LOCKSS team at Stanford. From there, it is transferred to the CLOCKSS boxes in the CLOCKSS PLN. The physical and informational security measures that protect these machines are set out in CLOCKSS: Threats and Mitigations and CLOCKSS: Box Operations.
