OAIS, Page 4-11, s. 4.1.1.5 "The Archival Information Update function provides a mechanism for updating the contents of the archive. It receives change requests, procedures and tools from Manage System Configuration. It provides updates by sending a dissemination request to Access, updating the contents of the resulting DIPs and resubmitting them as SIPs to Ingest."

Notes
  • This function is likely requesting AIP content delivered as as special configuration of DIPs which would not necessarily reach the average consumer. Consumer-bound DIPs could contain a subset of metadata used by the archive and/or a special access version of the Content Data Object (such as a compressed image or a file that has been redacted for public release), but for updating, a complete and full-sized version of the Content Data Object would be required. There is no function defined within OAIS which designs the DIP(s), and it is not made clear in OAIS if the DIP for updating is of a different design than the design(s) requested by the Consumer, but it must be.
