DD.2.2.5 Transmit SOP Instances to be Used

The Archive transmits the SOP Instances to be used as input information during the task to the Performing Device. This message would typically be conveyed using the Storage Service Class which could be initiated by the Performing Device via the Query/Retrieve Service Class based on information contained in the GP-SPS, or could also be initiated by the Archive or Workflow Manager in order to ensure the necessary SOP Instances are available before use.
