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.
After a SIP has been submited either by ESSArchs pre-ingest functionality or by a submission from another source such as an ERMS the SIP is accessible in ESSArchs Reception Area
This part of the process allows users to approve an AIP for storage or if necessary either by institution policy or issues with the IP-content to do further processing
ESSArch offers the possibility to use multiple storage methods and the same IP can be stored on multiple locations for maximal redundancy and disaster recovery purposes. ESSArch supports different storage technology Disk, Tape, Virtual Filesystems or Cloud services like AWS S3.
