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.
