For establishing leadership in IT-based engineering it offers a moderated platform to its nearly 200 members from leading industries, system
22、vendors and research institutions. Its product and process data standardization activities at European and worldwide levels are well known and accepted. The PROSTEP iViP Association sees this standard and the related parts as a milestone of product data technology. Users should note that all standar
23、ds undergo revision from time to time and that any reference made herein to any other standard implies its latest edition, unless otherwise stated.

24、ormation Package within the archive as overviewed in EN 9300-010. The main focus lies in the secure process, which implies the setting of digital signatures, disaster recovery and update of archive meta database. 2 Normative references The following documents, in whole or in part, are normatively re

30、e See Figure 1. Figure 1 Archival Storage The process 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 disast
31、er recovery of the stored data. Each company should 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 as
32、surance, Update meta-database and Disaster Recovery 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 Descriptive Information of
33、the Archive will be described in the recommended practices of the part 13. Input data: AIP DI Output data: Process control data BS EN 9300-013:2013EN 9300-013:2013 (E) 7 6 Detailed process steps description 6.1 General Input and output data described in this standard represent the minimal requiremen
34、ts 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 5.3.2.1 “Definition of the core model”). 6.2 AIP transfer to main storage The Archive transfers the AIP from the working envir
35、onment 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 process. Output data: Request for authentication Request for time stamp Secret key 6.4 Set digital time signature The archiv
36、e sets a digital (time) signature according to the applicable digital signature law. This assures the data integrity, readability and exchangeability during the retention period, and may be used as evidence when identifying the provenance of the information. NOTE A digital time signature is any uniq
37、ue 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 are formats such as email signatures and the simple attachment of signature images. Higher up the scale we find more secure f
38、ormats 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 data: Request for authentication Request for time stamp Secret key AIP Support information Output data: AIP Digital signatu
39、re information BS EN 9300-013:2013EN 9300-013:2013 (E) 8 6.5 Store to media The Archive stores the AIP physically onto a medium according to meet the requirements of long term archiving and the availability of the stored data. Input data: AIP Support information Output data: Storage information 6.6
40、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
41、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
42、surance and digital time signature information. Input data: Results Digital time signature information DI Output data: If update is successful: DI If update fails: Error report BS EN 9300-013:2013EN 9300-013:2013 (E) 9 6.8 Update meta database The archive generates a new entry within the archives me
43、ta database. The new entry contains the descriptive information, in addition for example, the reference information, which defines the storage location. Input data: DI Support information Output data: If update is successful: Meta database update report Meta database update information (Including th
44、e Descriptive Information) If update fails: Error report 6.9 Confirm the archiving The archive confirms the archiving process after the update of the meta database. Input data: Meta database update report Output data: Confirmation information 6.10 Generate confirmation report The archive generates a
45、 confirmation report which includes the feedback information for the consumer/ administrator according to the archiving/removal procedures. Input data: Confirmation information Output data: Archiving confirmation report 6.11 Receive confirmation (by the administrator) The administrator receives the
46、archives confirmation report. Input data: Confirmation report (for archiving) Output data: BS EN 9300-013:2013EN 9300-013:2013 (E) 10 6.12 Receive confirmation (by the producer) The producer receives the archives confirmation report. Input data: Confirmation report (for archiving) Output data: 6.13
47、Disaster Recovery The archive duplicates the AIPs and stores the duplicate in a physically separate facility. Input data: If disaster recovery is successful: AIP Meta database update information Output data: If disaster recovery fails Error report 6.14 Error handling for archival storage Within this
48、 process the Administrator has to perform error fixing procedures for the storage of archiving information packages, the update of meta database and the preparation for disaster recovery. Input data: Error report Output data: Process control data 6.15 Manual edition of Descriptive Information (by th
49、e producer) The Producer shall have the ability to edit and attach several descriptions to the AIPs. The additional Descriptive Information could be, for example, the end of production date for a product - this is not known at the date the data is stored. Input data: DI Output data: DI (completed by the producer) BS EN 9300-013:2013EN 9300-013:2013 (E) 11 6.16 Manual edition of Descriptive Information (by the administra
