This includes the phases: Data preparation Ingest Archival Storage Retrieva
21、l Removal The overview is organized along the life cycle of the data to be archived. For this the Producer has 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 Proce
22、ss the SIP will be converted into an Archival Information Package (AIP). This includes the conversion of native 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 arc
23、hived data. The archiving system provides in addition the optional Removal Process step. The ingest process 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
24、 Generation and Data Usage and Process step #7 Data usage are out of scope for EN 9300-010. The phases and the process step are integrated for process modeling reasons. The supporting processes (for example, “data preservation”, ”data management”, and “administration”) are not identified on the Figu
25、re 1. They will be introduced, when useful, on the parts detailing the processes (EN 9300-011 to EN 9300-015). prEN 9300-010:20066 The Descriptive Information is not identified on the Figure 1. It will be introduced, when useful, on the parts detailing the processes (EN 9300-011 to EN 9300-015). The
26、 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 archived information holdings. 6 Detailed process steps description 6.1 Data Preparation The
27、 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 requirements, and will provide a result report. Data preparation also includes the creation of vali
28、dation 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 environment into the archiving environment. The archive receives the data packages and checks if th
29、e 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. The sub process shall be certified. For details refer to EN 9300-012 “Ingest“. 6.3 Archival
30、 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 disaster recovery of the stored data. E
31、ach 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. For details refer to EN 9300-013 “Archival Storage“. 6.4 Retrieval The pr
32、ocess 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 Package (DIP). The generation of the DIP should meet the requirements of the Consumer. The s
33、ub 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 by the archive. The removal can be performed in two ways: Deletion of relevant data, or O
34、utsourcing 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 should be exercised before any data removal. prEN 9300-010:20067 The process includes access
35、 control functionality 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 dele
36、ted and provides 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 automaticall
37、y controlled 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 qu
38、ality criteria 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
39、functions of 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
40、archive to find 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 Certif
41、ication Agencies 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 Desig
42、ners, Design 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 Descr
43、iption Information (PDI) (Validation Properties, context information for the Content Information) Digital Signature Information 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
44、 information is the information that is used to bind and identify the components of an Information Package. Preservation Description Information is the information which is necessary for adequate preservation of the Content Information and which can be categorized as Provenance, Reference, Fixity, a
45、nd Context information. Digital Signature Information is the information about authenticity (identify the signature-key-owner), data integrity and time stamp. 7.2.2 Submission Information Package (SIP) The SIP consists of following main information objects: CI (native formatted data) PDI (Validation
46、 Properties, context information regarding the CI) PI 7.2.3 Dissemination Information Package (DIP) The DIP consists of following main information objects: CI (native formatted and optional archiving formatted) PI The Information Package will be generated by the archive in answer to a consumers requ
47、est. The DIP may contain collections of AIP. The AIP Content Information will be converted into the data format of the Consumers target system. 7.2.4 Copy of AIP Copy of stored AIP. The original AIP remains within the archive. prEN 9300-010:20069 Bibliography 1 ISO 10303, Industrial automation syste
