12、 other standard implies its latest edition, unless otherwise stated. prEN 9300-014:20064 1 Scope EN 9300-014 provides a detailed description for the recommended process of retrieval of 3D and PDM data. A main focus lays on the secure process, which implies the defined search for archived data elemen

13、ts and the dissemination of the data packages, which includes e.g. the check for digital signatures or the validation of archived data as overviewed in EN 9300-010. 2 Normative references The following referenced documents are indispensable for the application of this document.

Figure 1 Retrieval The process includes a recommended access check, provide

19、s functionality for a data search to select the required data (provided the Consumer is allowed to see it), and the generation of a Dissemination Information Package (DIP). The generation of the DIP should meet the requirements of the Consumer. The sub process shall be certified. Input data: Retriev

20、al request Output data: DIP 6 Detailed 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 pac

21、kage. (See EN 9300-003, section 5.3.2.1 “Definition of the core model”). prEN 9300-014:20066 6.2 Request retrieval data The role Consumer/Administrator initiates a retrieval request for a data package. The request shall contain all information needed for the successful retrieval process i.e. selecti

22、on of requested data, data format required for the DIP and any validation information required. Output data: Request 6.3 Access The Archive centrally supervises the access rights for each role. The supervisor check if the role has the access rights for triggered queries. Input data: Request Output d

23、ata: Access granted information 6.4 Data selection The Archive provides the functions to search for the requested data. This includes the verification of access rights and methods for filtering the selection; according to access rights, It may be implemented in batch or interactive mode. The filteri

24、ng may result in successive and related requests from the consumer. It may implemented in batch or interactive mode. The filtering may result in successive and related requests of the consumer. Input data: Request Access granted information Support information Output data: Selection information 6.5

25、Prepare data for dissemination The archive checks the usability of data and the copies the AIP for dissemination. Input data: Selection information Support information Output data: Copy of AIP prEN 9300-014:20067 6.6 Generate DIP The archive generates the Dissemination Information Package (DIP), whi

26、ch is derived from one or more AIPs. The DIP generation includes any conversion of Content Information/ Preservation Description Information into the required data format and validates the converted data. This sub process shall be certified. The archive and the consumer shall define an agreement for

27、 each category of product information to preserve. It shall include at a minimum the specification of: preserved the key characteristics of the product information, the defined Descriptive Information of the SIP, the control criterias used for the verification, the validation properties of the sourc

28、e information to archive, the related KPIs. The Generate DIP Process includes some Error handling Procedures which secures the consistency of the DIP within the retrieval Process. Input data: Copy of AIP Support information Output data: Dissemination Information Package (DIP) 6.7 Provide DIP The arc

29、hive transfers the DIP from archive environment to consumers working environment. Input data: DIP Output data: DIP 7 Support Process Steps: 7.1 Preservation Planning The process provides services and functions for monitoring the environment of the archive and recommendations to ensure that the infor

30、mation stored in 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,

31、 archiving format and the addressed consumer. Output data: Support information prEN 9300-014:20068 7.2 Data Management The Data Management is responsible for maintaining the integrity of the Data Management database, which contains both Descriptive Information and system information. The Data Manage

32、ment is responsible for creating any schema or table definitions required to support Data Management functions; for providing the capability to create, maintain and access customized user views of the contents of this storage; and for providing internal validation (e.g., referential integrity) of th

33、e contents of the database. A log describing the history of activity in the repository shall be archived. The Data Management is carried out in accordance with policies received from Administration. Output data: Support information 8 Data description 8.1 General The descriptions here are informative

34、; the definitions are found in the part EN 9300-007. 8.2 Involved roles: 8.2.1 Archive The Archive is the archiving system, which usual supports at least the key functions of an archiving architecture according to ISO 14721:2003 (OAIS). Key functions are administration, data management, archival sto

35、rage, access control, preservation planning). 8.2.2 Consumer The consumer is an organization, person, or client system, which interact with the services offered by the archive to find preserved information of interest and to access that information in detail. This can include other archives, as well

36、 as internal archive persons or system components. Typical roles of type “consumer“ may be Design Engineers, Suppliers, Manufactures, Customers, Regulatory Agencies or Quality. 8.2.3 Administrator Administrator is the role (organization or person), which is responsible for the management of the arch

37、ive and daily operation. The role performs actions such as access control, monitoring and error handling. The role is not directly involved in the archiving and retrieval processes. The role may not be responsible for the administration of further external tools like quality agents, the evolved TDM,

38、 CAx, PDM or Data Exchange applications. 8.3 Involved data: 8.3.1 Archival Information Package (AIP) The AIP consists of following main information objects: Content Information (archiving formatted and optional native formatted) Packaging Information Preservation Description Information (Validation

39、Properties, context information regarding the Content Information) Digital Signature Information prEN 9300-014:20069 The Content Information is a set of information that is of main interest and has all the qualities needed for permanent storage. Packaging information shall be that kind of informatio

40、n that is used to bind and identify the components of an Information Package. Preservation Description Information is the kind of information which is necessary for adequate preservation of the Content Information and which can be categorized as Provenance, Reference, Fixity, and Context information

41、. Digital Signature Information is the information about authenticity (identify the signature-key-owner), data integrity and time stamp information. 8.3.2 Dissemination Information Package (DIP) The DIP consists of following main information objects: Content Information (this may include native form

42、at and archive format) Packaging Information The Information Package will be generated by the archive as an answer to a consumers request. The DIP may contain collections of AIPs. The AIP Content Information will be converted into the data format of the target system. 8.3.3 Access granted informatio

43、n Contains the verification of the requesters access rights. 8.3.4 Request Manually generated request from the Consumer, or from the Administrator, which can consist, for example, of partial or full part number or assembly knot information. The access request will be transferred to the archive front

44、end. The request must contain the account information, such as name and/or password of the current user. 8.3.5 Selection information Contains a list of selected documents for retrieval. 8.3.6 Copy of AIP Copy of stored AIP. The original AIP remains within the archive. 8.3.7 Support Information Gener
