19、 1. Figure 1 Removal Overview The data removal can be initiated either by the rules management/administrator or an automatic request generated by the archive. The removal can be performed in two ways: Deletion of relevant data, or Outsourcing of data into a e.g. (technical) museum, which does not ob

20、ey the terms and conditions of a long term archive. The process includes an access control functionality for security reasons and a data selection functionality for the manual selection. The Content Information of the AIP will be deleted form the archive, but the deletion information remains within

21、the archives meta data. The remove process checks afterwards the correct data deletion and provides a status report. Because of the fact that data shall be stored permanently, every company has to decide if a removal process of data should be implemented. Inappropriate Removal of data may cause diff

22、iculties in data path traceability. Caution should be exercised before any data removal is authorised and carried out. The process steps #5 delete CI and PDI of AIP and #6 error check removal AIP are integrated for process modelling (completeness) reasons. prEN 9300-015:20066 6 Detailed process step

23、s 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 5.3.2.1 “Definition

24、 of the core model”). 6.2 Removal request The management should decide on the length of retention periods and should confirm the removal requirements. If data is declared as removable, the management initiates a removal request for the archive. Input data: Automatic removal query (optional) Output d

25、ata: Removal request 6.3 Initiate removal process The administrator has to initiate the removal process after getting the management notification of the removal of defined information. Input data: Removal request Output data: Request 6.4 Access The Archive centrally supervises the access rights for

26、each role. The supervision checks if the role has the access rights for triggered queries. Input data: Removal request Output data: Access granted information Request 6.5 Data selection removal The Archive provides functions to search for the requested data. This includes the verification of access

27、rights and methods of filtering the selection, according to access rights. Before removing data, a check should be made to identify any dependent data. The removal should terminate if related data is present. Removal should also be denied if such a removal breaks data continuity from an audit point

28、of view. prEN 9300-015:20067 Data selection removal should include a confirmation about the physical deletion of the selected data. Input data: Request Access granted information Output data: Selection information 6.6 Delete Content Information and Preservation Descriptive Information of AIP The Arc

29、hive deletes the CI and PDI from the physical storage. The AIP Descriptive Information will remain within the Archives meta data base and will be updated with the deletion information of that AIP. Input data: Selection information Output data: Confirmation deletion information 6.7 Error check remova

30、l AIP The Archive checks the complete deletion of Content Information and Preservation Description Information from the archives physical storage. Input data: Confirmation deletion information Output data: Results error report removal 6.8 Add removal information to descriptive information The Archiv

31、e logs the deletion of the Content Information, of the Preservation Description Information, and updates its meta data base. The update can contain the following entries: Deletion of which AIP Deletion date and time Who initiated the deletion Input data: Results error report removal Output data: Met

32、a data base update information prEN 9300-015:20068 6.9 Confirmation of removal The archive confirms the complete deletion of the AIP and the update of its meta data base for the belonging AIP. Input data: Meta data base update information Output data: Remove confirmation information 6.10 Generate co

33、nfirmation report The Archive generates a confirmation report, which includes the feedback information for the administrator about the removal procedures. Input data: Removal confirmation information Output data: Confirmation report 6.11 Receive confirmation report The Administrator receives the rem

34、oval confirmation report. Input data: Confirmation Report 6.12 Automatic removal request The Archive generates an automatic removal request: The request is based on domain dependent requirements. This can include expired archiving periods for documents e.g. 50 years. After this archiving period the

35、data could be deleted, after review by the administration organization or the custodian of the product data Input data: Rules for automatic removal request Output data: Automatic removal request 6.13 Error report of removal In cases of partly deletion of AIP information the archive generates an erro

36、r report, the error report provides the deletion failures information. Input data: Results error removal report Output data: Error removal report prEN 9300-015:2006 9 6.14 Error handling for AIP deletion failures The Administrator has to perform an error handling procedure in cases of partly deletio

37、n of AIPs. This includes the manual deletion of relevant information. Input data: Error removal report 7 Support process step: Preservation Planning The process provides services and functions for monitoring the environment of the archive, and recommendations to ensure that the information stored in

38、 the archive remains accessible to the consumer over the long term, even if the original computing environment becomes obsolete. Preservation Planning functions include developing recommendations for archive standards and policies and monitoring changes in the technology environment, archiving forma

39、t and the addressed consumer. 8 Data descriptions 8.1 General The descriptions here are informative; the definitions are found in the part EN 9300-007. 8.2 Involved Roles: 8.2.1 Management Management is the role (organization or person), which is responsible for the management of the aircraft produc
