This section explains about working with resource metadata and managing revisions using the "Create Checkpoint" and "View versions" options. Revisions are a useful way to facilitate Disaster Recovery and Fault Tolerance in Governance Registry. By creating a revision, a user essentially saves a snapshot of the current state of a resource or collection which can be restored at a later date. The Governance Registry's checkpoint and restoration mechanisms are similar to that of System Restore of Microsoft Windows.

  • Created - Shows the time when a resource was created and the author of a resource/collection.
  • Last Updated - Shows the time when a resource was updated and the author of alterations/collection.
  • Media Type - An associated Media type of the resource/collection.For more information about Media types, please, visit the Adding a Resource page.
  • Checkpoint - Allows to create a checkpoint (URL for the permanent link) of a resource/collection.
