The Negotiate Submission Agreement function solicits desirable archival information for the OAIS and negotiates Submission Agreements with Producers. This function also negotiates a data submission schedule with the Producer. It maintains a calendar of expected Data Submission Sessions that will be needed to transfer one or more SIPs to the OAIS and the resource requirements to support their ingestion. This function receives AIP/SIP templates and customization advise from Preservation Planning and sends SIP designs and SIPs to the Audit Submission function as part of the submission approval process. The data submission formats and procedures must be clearly documented in the archive's data submission policies, and the deliverables must be identified by the Producer in the Submission Agreement.
