13、Subcommittee SC 4, Industrial data. This first edition of ISO 8000-120 cancels and replaces ISO/TS 8000-120:2009, which has been technically revised. ISO 8000 is organized as a series of parts, each published separately. The structure of ISO 8000 is described in ISO/TS 8000-1. Each part of ISO 8000

14、is a member of one of the following series: general data quality, master data quality, transactional data quality, and product data quality. This part of ISO 8000 is a member of the master data quality series. A list of all parts in the ISO 8000 series can be found on the ISO website.iv ISO 2016 All

15、 rights reserved ISO 8000-120:2016(E) Introduction The ability to create, collect, store, maintain, transfer, process and present data to support business processes in a timely and cost effective manner requires both an understanding of the characteristics of the data that determine its quality, and

16、 an ability to measure, manage and report on data quality. ISO 8000 defines characteristics that can be tested by any organization in the data supply chain to objectively determine conformance of the data to ISO 8000. ISO 8000 provides frameworks for improving data quality for specific kinds of data

17、. The frameworks can be used independently or in conjunction with quality management systems. ISO 8000 covers industrial data quality characteristics throughout the product life cycle from conception to disposal. ISO 8000 addresses specific kinds of data including, but not limited to, master data, t

18、ransaction data, and product data. ISO 8000-110 specifies requirements that can be checked by computer for the exchange, between organizations and systems, of master data that consists of characteristic data. It provides requirements for data quality, independent of syntax. This part of ISO 8000 spe

19、cifies requirements for capture and exchange of data provenance information and supplements the requirements of ISO 8000-110. This part of ISO 8000 includes a conceptual data model for data provenance. Data provenance information can be used to detect data echoes, and can be used to determine the cr

20、edibility, currency or value of data. Data provenance information provides a necessary capability to support claims of data accuracy. NOTE Requirements regarding claims of data accuracy are covered in ISO 8000-130. Any claim of conformance to this part of ISO 8000 implies a claim of conformance to I

21、SO 8000-110. This part of ISO 8000 can be used with any other standard that specifies a formal syntax for a data set. ISO 2016 All rights reserved v Data quality Part 120: Master data: Exchange of characteristic data: Provenance 1 Scope This part of ISO 8000 specifies requirements for the representa

22、tion and exchange of information about the provenance of master data that consists of characteristic data, and supplements the requirements of ISO 8000-110. NOTE 1 ISO 8000-110 specifies that such data be represented as property values. This part of ISO 8000 provides additional requirements for prop

23、erty values when provenance information needs to be captured. Provenance is the history or pedigree of a property value. This part of ISO 8000 does not specify a complete model for characteristic data, nor does it specify an exchange format for characteristic data with provenance information. NOTE 2

24、 This is done in other standards that reference this part of ISO 8000, e.g. ISO 22745-40. The following are within the scope of this part of ISO 8000: scenarios for data provenance; requirements for capture and exchange of data provenance information; conceptual data model for data provenance inform

25、ation. The following are outside the scope of this part of ISO 8000: exchange format for data provenance information; scheme for registering and resolving organization identifiers and person identifiers; provenance of data that are not characteristic data represented as property values; configuratio

26、n management; change control; syntax of identifiers; resolution of identifiers. Some of the requirements in this part of ISO 8000 can apply to exchange of data that is not master data which consists of characteristic data represented as property values. NOTE 3 ISO 8000-100 provides an overview of th

27、e master data quality series of parts of ISO 8000 and a description of its overall structure. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edi

28、tion of the referenced document (including any amendments) applies.

32、, pv2, etc. null no value given 5 Fundamental concepts and assumptions The Oxford English Dictionary defines provenance as: the fact of coming from some particular source or quarter; origin, or derivation; the history or pedigree of a work of art, manuscript, rare book, etc.; concretely a record of

33、the ultimate derivation and passage of an item through its various owners. In this part of ISO 8000, the term “data provenance” corresponds to the first part of the second definition above: “history or pedigree of a property value”; the term “provenance record” corresponds to the second half of seco

34、nd definition above: “record of the ultimate derivation and passage of a property value through its various custodians”.2 ISO 2016 All rights reserved ISO 8000-120:2016(E) 6 Provenance data model 6.1 Diagram The UML class diagram for the provenance model is given in Figure 1. Figure 1 UML class diag

35、ram for provenance NOTE The entity property_value_assignment is the intersection point between this data model and the target data model: the model of data for which provenance information is to be recorded. When the data model in Clause 6 is integrated with the target data model, this entity needs

36、to be replaced with the appropriate entity from the target data model. 6.2 date_and_time A date_and_time is a point in time, expressed in Universal Coordinated Time (UTC). 6.3 ISO_6523_identifie r An ISO_6523_identifier is an identifier of an organization and possibly a subdivision of an organizatio

37、n, conforming to the structure specified in ISO/IEC 6523-1. NOTE The syntax of ISO/IEC 6523-1 identifiers is not specified in this part of ISO 8000. 6.4 property_value_assignment A property_value_assignment is a data_object that is a pair of a value and an identifier to a property defined in a data

38、dictionary. Attribute definitions: ID: the string that unambiguously identifies the property_value_assignment within the organization that created it. NOTE 1 The identifier need only be unique or meaningful within the organization that created the property_value_assignment. NOTE 2 The format of the

39、identifier is not specified in this part of ISO 8000. provenance: the provenance_event that provides information on the provenance of the proper- ty_value_assignment. ISO 2016 All rights reserved 3 ISO 8000-120:2016(E) Assertions: Each property_value_assignment has its provenance recorded by one or

40、many provenance_event objects. Each provenance_event records the provenance for exactly one property_value_assignment. 6.5 provenance_event A provenance_event is an event for which data provenance information is recorded. Attribute definitions: event_type: the event for which data provenance informa

41、tion is recorded. organization_ref: the unambiguous identifier of the organization and possibly the subdivison of the organization that performed the event, conforming to the structure defined in ISO/ IEC 6523-1 and assigned in accordance with ISO/IEC 6523-2. person_ref: the identifier assigned by t

42、he organization to the person who performed the event. NOTE 1 The identifier need only be unique within the organization. NOTE 2 The format of the identifier is not specified in this part of ISO 8000. role_ref: the identifier assigned by the organization to the role within the organization played by

43、 the person who performed the event. NOTE 3 The identifier need only be unique within the organization. NOTE 4 The format of the identifier is not specified in this part of ISO 8000. when: the point in time at which the event took place. Assertions: Each provenance event records the provenance for e

44、xactly one property_value_assignment. Each property_value_assignment has its provenance recorded by one or many provenance_event objects. 7 Data provenance record The data provenance record for a property value is the record of the ultimate derivation and passage of the property value through its va

45、rious custodians. The data provenance record for a property value shall be either: included in the structure that represents property value; EXAMPLE 1 The following is an XML code fragment in which the data provenance record is included in the XML structure that represents property value. Coded:Deco

46、ded:4 ISO 2016 All rights reserved ISO 8000-120:2016(E) stored separately and referenced from the structure that represents property value. EXAMPLE 2 The following is an XML code fragment in which the data provenance record is referenced from the XML structure that represents property value. Coded:.

47、Decoded:.NOTE 1 See D.1 for an explication of the codes in the examples above. NOTE 2 This part of ISO 8000 does not require that a master data message use the specific structures shown in the examples above, or that it use XML syntax at all. NOTE 3 In the examples above, data are given in coded for

48、m followed by decoded form for clarity. An actual master data message is required to be in coded form (see ISO 8000-110). The data provenance record for a property value shall include: identification of the data creator (the organization, and possibly the person and role within the organization, tha

49、t created the data); identification of each data extractor (the organization, and possibly the person and role within the organization, that extracted the data). NOTE 4 As specified in 6.5, the following information is required for a provenance event: event type (e.g. “create”, “extract”); ISO 2016 All rights reserved 5 ISO 8000-120:2016(E) organization reference; event date and time. 8 Conformance requirements Any property value for which conformance to this part of ISO 8000 is claimed shall: c
