ESSArch is based on OAIS (Open Archival Information System, ISO 14721:2003) and further on developed to include both PreIngest and PreAccess functions, Storage Methodes and flexibility to add any metadata standard required. The main conceptual functions are based on traditional archiving preservation processes.
ESSArch supports the specifications used by the National Archives of Sweden (FGS) and Norway we also have strong support for the EARK-specifications which we also have contributed to.
