Readers of this standard should note that all standards undergo periodic revisions and that any reference made herein to any oth

12、er standard implies its latest edition, unless otherwise stated. The Standards will be published under two different standards organizations using different prefixes. ASD-Stan will publish the standard under the number EN 9300xxx. AIA will publish the standard under the number NAS 9300xxx. The conte

13、nt in the EN 9300 and NAS 9300 documents will be the same. The differences will be noted in the reference documentation (i.e. for EN 9300 Geometric Dimensioning it corresponds generally to the design stage of the Product Model; this Working Form is often in the native format of the COTS application.

14、 3.2 Definitions The following section provides a list of general terms that occur in the EN 9300 documentation, together with a definition of those terms. These definitions are either cited from other standards, or defined as part of the EN 9300 standard, and are normative. NOTE the source for the

15、definition is noted after the term. Where the sources are noted as OAIS, this is taken from CCSDS 650.0-b-1, 1.72 “Terminology“. Additional terms are also defined by OAIS, however only the most significant are reproduced here. Archival Information Package (OAIS) - An Information Package, consisting

16、of the Content Information and the associated Preservation Description Information (PDI), which is preserved within an OAIS. (Note - this is the package actually retained by the archive, containing both the Content Information and all necessary PDIs.) Archival Storage (OAIS, cf also EN 9300-10 6.3 a

17、nd EN 9300-13) - The process includes the setting of digital time signatures, generation of additional Descriptive Information for Archive Information Packages (meta data for the archive) and the physical storage of the data within the archive. Archive (OAIS, cf also EN 9300-10 7.1.1) - The Archive

18、is the archiving environment, which usual supports at least the key functions of an archiving architecture according ISO 14721 (OAIS). Administration (OAIS cf also EN 9300-13 7.3) - The management of the archive and its daily operation. Administrator (OAIS cf also EN 9300-13 8.1.3) - The organizatio

19、n or person responsible for management of the archive and its daily operation. Consumer (OAIS, cf also EN 9300-10 7.1.2) - 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 i

20、nformation in detail. prEN 9300-007:2012 (E) 10 Content Information (OAIS) - The set of information that is the original target of preservation. It is an Information Object comprised of its Content Data Object and its Representation Information. An example of Content Information could be a single ta

21、ble of numbers representing, and understandable as, temperatures, but excluding the documentation that would explain its history and origin, how it relates to other observations, etc. Context Information (OAIS) - The information .that documents the relationships of the Content Information to its env

22、ironment. This includes why the Content Information was created and how it relates to other Content Information objects. Core Model (EN 9300-003, 5.3.2.1) - The essential minimum of data which are required to preserve the design intent for a given purpose. Data (ISO 10303-1) - A representation of in

23、formation in a formal manner suitable for communication, interpretation, or processing by human beings or computers. Data Preparation (EN 9300-010 6.1 and EN 9300-011) - The data to be archived will be prepared by the producer. This includes data verification. Data Selection (EN 9300-014 6.3) - The

24、functions to search the archive for data. Descriptive Information (OAIS) - The set of information, consisting primarily of Package Descriptions, which is provided to Data Management to support the finding, ordering, and retrieving of OAIS information holdings by Consumers. (OAIS) - The Information P

25、ackage, derived from one or more AIPs, received by the Consumer in response to a request to the OAIS. Engineering signature (EN 9300-005) - A digital signature with which the data producer asserts that the prepared data fits with the process and quality requirements from the engineering point of vie

26、w. NOTE The terminology of part 5 clarifies the term “Digital (engineering) signature“ from EN 9300-003, 5.3.2.3. Fixity Information (OAIS) - The information which documents the authentication mechanisms and provides authentication keys to ensure that the Content Information object has not been alte

27、red in an undocumented manner. Information (ISO 10303-1) - Facts, concepts, or instructions. Ingest (OAIS, cf also EN 9300-010 6.2 and EN 9300-012) - During the Ingest process the data producer submits the Submission Information Package from the data preparation environment into the archiving enviro

28、nment. Key Characteristic - (EN 9100:2003, which in turn is based on ISO 9001:1994) - The features of a material or part whose variation has a significant influence on product fit, performance, service life or manufacturability. Long Term Archiving (EN 9300-003, 3.2.5) - Storage of a copy of data in

29、 an appropriate way for record, certification and legal purposes: The data will be preserved and kept available for a use within the archive and possibly for further re-use; With certified conversion processes, the native data representation generated by the source system can be converted into a rep

30、resentation which is appropriate for long term archiving. To fulfil legal and certification requirements, the stored form can be an accurate or approximate representation of the source; Integrity must be ensured by a digital signature; The data is retained over the long term; Invariance is mandatory

31、; Business, legal and certification requirements are covered. prEN 9300-007:2012 (E) 11 Open Data Standard is an Open Standard (see below) defining the syntax, semantics and pragmatics of a data model. Open Standard is a standard that must fulfil the following criteria: Described precisely in a way

32、that is widely and freely available and does not use proprietary methods or practices (e.g. uses object modelling methods using UML or EXPRESS) and includes defined semantics; Format and services implementing the data are explicitly described (e.g., STEP Part 21 or XML, PLM services, binary/text for

33、mats, etc.) and documentation of the format and services is readily available; The updating process is described and well accepted by the applicable community and all organizations in that community are able to comment and participate in the approval process (e.g., STEP ISO ballot procedures, OMG an

34、d W3C consortium procedures); Responsibility for maintaining the standard is clearly defined and held by a responsive organization; The standard and its documentation is publicly available, is not restricted by royalties, patents or other Intellectual Property restrictions, except possibly copyright

35、, in which case copies must be available at reasonable cost. Packaging Information (from OAIS) - The information that is used to bind and identify the components of an Information Package. For example, it may be the ISO 9660 volume and directory information used on a CD-ROM to provide the content of

36、 several files containing Content Information and Preservation Description Information. Producer (OAIS cf also EN 9300-010 7.1.3) - The producer is an organization, person, or client system, which provides the information to be preserved. Preservation Description Information (OAIS) - the information

37、 which is necessary for adequate preservation of the Content Information and which can be categorized as Provenance, Reference, Fixity, and Context information. Product (From ISO 10303-1) - A thing or substance produced by a natural or artificial process. (See also see “Product, Part, Item and Artic

38、le“ in Terms (3.1 above). Product data (From ISO 10303-1) - A representation of information about a product in a formal manner suitable for communication, interpretation, or processing by human beings or by computers. Provenance Information (OAIS) - The information that documents the history of the

39、Content Information. This information tells the origin or source of the Content Information, any changes that may have taken place since it was originated, and who has had custody of it since it was originated. Retention - (9300-003, 3.2.4) - Storage of data for reuse at a later date: Aiming for dat

40、a re-use and to keep data available Retaining any of the representations needed, but not the presentations Working over medium and short term Expecting invariance, though this is not mandatory Migration of the data format is allowed to guaranty data quality and interpretability. Removal (OAIS, cf al

41、so EN 9300-010 6.5 and EN 9300-015) - Deletion of data or outsourcing of data, for example into a technical museum, which does not meet the requirements of a long term archive. prEN 9300-007:2012 (E) 12 Retrieval (OAIS cf also EN 9300-010 6.4 and EN 9300-014) - Retrieval provides functionality for a

42、 data search to select the required data (provided the Consumer is allowed to see it), and the generation of a Dissemination Information Package (DIP). Submission Information Package (OAIS) - An Information Package that is delivered by the Producer to the OAIS for use in the construction of one or m
