23、00-010:20065 5 Overview data flow Figure 1 Overview data flow The overview data flow is divided into several phases. This includes the phases: Data preparation Ingest Archival Storage Retrieval Removal The overview is organized along the life cycle of the data to be archived. For this the Producer h
24、as to prepare the data. After Data Preparation the resulting Submission Information Package (SIP) will be send during an Ingest Process to the Archive System. Within the Archival Storage Process the SIP will be converted into an Archival Information Package (AIP). This includes the conversion of nat
25、ive formatted product data into the archive format as well as the signing of the data with a digital time signature. For reuse or viewing, the data Consumer has the ability to retrieve the archived data. The archiving system provides in addition the optional Removal Process step. The ingest process
26、for pre existing data describes the automatic process of conversion and storage of an already existing archive (and data) into the recommended archive format (See EN 9300-016). The phases Data Generation and Data Usage and Process step #7 Data usage are out of scope for EN 9300-010. The phases and t
27、he process step are integrated for process modeling reasons. The supporting processes (for example, “data preservation”, ”data management”, and “administration”) are not identified on the Figure 1. They will be introduced, when useful, on the parts detailing the processes (EN 9300-011 to EN 9300-015
28、). Copyright Association Europeene des Constructeurs de Materiel Aerospatial Provided by IHS under license with AECMA Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-prEN 9300-010:20066 The Descriptive Information is not identified on the Figure 1. It will be intro
29、duced, when useful, on the parts detailing the processes (EN 9300-011 to EN 9300-015). The Descriptive Information represents the set of information, consisting primarily of Package Descriptions, which is provided to Data Management to support the finding, ordering, and retrieving by Consumers of ar
30、chived information holdings. 6 Detailed process steps description 6.1 Data Preparation The data to be archived will be prepared by the producer. This includes defined data verification, performed by a Quality Agent tool. The data verification will test the data against defined data quality requireme
31、nts, and will provide a result report. Data preparation also includes the creation of validation properties. The sub process shall be certified. For detailed refer to EN 9300-011 “Data Preparation“. 6.2 Ingest During the Ingest process the data producer submits the SIP from the preparation environme
32、nt into the archiving environment. The archive receives the data packages and checks if the SIP contains data of the recommended format and then generates the AIP. It is recommended that the Producer environment makes the source data read only after successful submission of the SIP to the archive. T
33、he sub process shall be certified. For details refer to EN 9300-012 “Ingest“. 6.3 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 arch
34、ive and error checking as well as the steps needed disaster 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 sha
35、ll be certified. For details refer to EN 9300-013 “Archival Storage“. 6.4 Retrieval The process includes a recommended access check, provides 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 Pa
36、ckage (DIP). The generation of the DIP should meet the requirements of the Consumer. The sub process shall be certified. For details refer to EN 9300-014 “Retrieval“. 6.5 Removal Data removal can be initiated either by the rules management system or administrator or by an automatic request generated
37、 by the archive. The removal can be performed in two ways: Deletion of relevant data, or Outsourcing of data, for example into a (technical) museum, which does not meet the requirements of a long term archive. Inappropriate removal of data may cause difficulties in data path traceability. Caution sh
38、ould be exercised before any data removal. Copyright Association Europeene des Constructeurs de Materiel Aerospatial Provided by IHS under license with AECMA Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-prEN 9300-010:20067 The process includes access control fun
39、ctionality for security reasons and data selection functionality for manual selection. The Content Information of the AIP will be deleted from the archive, but the deletion information remains within the archives meta data. The removal process checks afterwards the data is correctly deleted and prov
40、ides a status report. Because data may be stored on permanent media, each company has to decide if a removal process of data be implemented. The implementation of this process is optional. For details refer to EN 9300-015 “Removal“. 6.6 Ingest of pre existing data Within the automatically controlled
41、 Ingest process for pre existing data, the pre existing data (archive) will be converted into the recommended archiving format and stored in the long term archive. This process step is only relevant for pre existing 3D product data, e.g. CAD and PDM data, which fulfil the defined data quality criter
42、ia of this reference process. In case of implementation, the process shall be certified. For details refer to EN 9300-016 “Ingest for pre existing data”. 7 Data descriptions 7.1 Involved roles: 7.1.1 Archive The Archive is the archiving environment, which usual supports at least the key functions of
43、 an archiving architecture according to ISO 14721 (OAIS). Key functions are administration, data management, archival storage, access control, preservation planning. 7.1.2 Consumer The consumer is an organization, person, or client system, which interact with the services offered by the archive to f
44、ind preserved information of interest and to access that information in detail. This can include other archives, as well as internal archive personnel or system components. Typical roles of type “consumer“ may be Design Engineers, Suppliers, Manufactures, Customers, Regulatory and Certification Agen
45、cies or Quality Departments. 7.1.3 Producer The producer is an organization, person, or client system, which provides the information to be preserved. This can include other archives or internal archive personnel or system components. Typical roles of type “producer“ may be. System Designers, Design
46、 Engineers, Subcontractors, Manufactures or Test Engineers. 7.2 Involved data: 7.2.1 Archival Information Package (AIP) The AIP consists of the following elements: Content Information (CI) (archiving formatted and optionally native formatted) Packaging Information (PI) Preservation Description Infor
47、mation (PDI) (Validation Properties, context information for the Content Information) Digital Signature Information Copyright Association Europeene des Constructeurs de Materiel Aerospatial Provided by IHS under license with AECMA Not for ResaleNo reproduction or networking permitted without license
48、 from IHS-,-,-prEN 9300-010:20068 The Content Information is the set of information that the producer requires to retain and has all the qualities needed for permanent storage. Packaging information is the information that is used to bind and identify the components of an Information Package. Preser
49、vation Description Information is the information which is necessary for adequate preservation of the Content Information and which can be categorized as Provenance, Reference, Fixity, and Context information. Digital Signature Information is the information about authenticity (identify the signature
