E-ARK specifications are supported by several procedures outlining, for example, the creation and maintenance of the specifications. You can find these documents on our Procedures page.
There is one supporting guideline for each E-ARK core specification (CSIP, E-ARK SIP, E-ARK AIP, E-ARK DIP, Archival Information, Preservation Metadata). We have also provided a small guide on how GitHub is used for managing the specifications. You can find these documents on our Supporting guidelines page.
