16、9300-013 provides a detailed description for the recommended process of the Archival Information Package within the archive as overviewed in EN 9300-010. A main focus lays on the secure process, which implies the setting of digital signatures, disaster recovery and update of archive meta data base.

Figure 1 Archival Storage The proce
23、ss includes the setting of digital time signatures, generation of additional Descriptive Information (DI) for AIPs (meta data for the archive), the physical storage of the data within the archive and error checking as well as the steps needed disaster recovery of the stored data. Each company should
24、 meet the general recommendations for an archive system and its security, as for example described in ISO 14721:2003 (OAIS). These general recommendations are out of scope. The sub process shall be certified. Process Steps Store to Media, Storage assurance, Update meta-database and Disaster Recovery
25、 cover administrative aspects of the archive and its software. The steps are out of scope for the process description and this standard. They are shown for completeness. If needed by the community, the preservation of the Desciptive Information of the Archive will be described in the recommended pra

27、iled process steps description 6.1 General Input and output data described in this standard represent the minimal requirements for the fulfilment of the process steps. Additional data may be added, but must match at a minimum the requirements for the information package. (See EN 9300-003, section 5.
28、3.2.1 “Definition of the core model”). 6.2 AIP transfer to main storage The Archive transfers the AIP from the working environment to the physical storage environment. Input data: AIP Output data: AIP 6.3 Initiate digital time signature process The administrator initiates the digital time signature
29、process. Output data: Request for authentication Request for time stamp Secret key 6.4 Set digital time signature The archive sets a digital (time) signature according to the applicable digital signature law. This assures the data integrity, readability and exchangeability during the retention perio
30、d, and may be used as evidence when identifying the provenance of the information. NOTE A digital time signature is any unique set of letters, characters, symbols or code attached to a digital document with the intention of identifying the sender. At the lower end of the e-signature security scale a
31、re formats such as email signatures and the simple attachment of signature images. Higher up the scale we find more secure formats such as pin numbers. At the upper end of the scale are formats using more complex technologies combining mathematical processes, encryption and controlled systems. Input

Input data: AIP Support information Output data: Storage information 6.6
34、Storage assurance The storage assurance function validates the successful transfer of the AIP to the staging area. For digital submissions, these mechanisms might include Cyclic Redundancy Checks (CRCs) or checksums associated with each data file, or the use of system log files to record and identif
35、y any file transfer or media read/write errors. Input data: Storage information Output data: In any case: Statistics If assurance is successful: Results If assurance fails: Error report 6.7 Update Descriptive Information The archive updates the set of descriptive information regarding the storage as
