The work of preparing International Standards is normally carried out thro
7、ugh ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collabor
8、ates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval
9、criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

The committee responsible for this document is Technical Committee ISO/TC 184, Automation systems and integration, Subcommittee SC 4, Industrial data. This first edition of ISO 8000-130 c
13、ancels and replaces ISO/TS 8000-130:2009, 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 is a member of one of the following series: general data quality, master
14、 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 rights reserved ISO 8000-130:2016(E) Introduction The ability to create
15、, 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 an ability to measure, manage and report on data quality. ISO 8000 defi
16、nes 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. The frameworks can be used independently or in conjunction with qualit
17、y 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, transaction data, and product data. Data is created as the result of a pr
18、ocess, typically an observation, a measurement or a transformation. While the accuracy of the process will determine the accuracy of the data in terms of its proximity to the true value, the accuracy of the transfer of the data from one system to another can also affect data accuracy. The accuracy o
19、f a transfer of data can be measured by comparison to authoritative data source. This part of ISO 8000 is an optional addition to ISO 8000-120 and specifies requirements for representation and exchange of information about accuracy of master data that consists of characteristic data. ISO 8000-120 is
20、 an optional addition to ISO 8000-110 and specifies requirements for representation and exchange of information about provenance of master data that consists of characteristic data. ISO 8000-110 specifies basic requirements for representation and exchange of information about provenance of master da
21、ta that consists of characteristic data, in particular, conformance to a formal syntax, semantic encoding, and conformance to a data specification. ISO 2016 All rights reserved v Data quality Part 130: Master data: Exchange of characteristic data: Accuracy 1 Scope This part of ISO 8000 is an optiona
22、l addition to ISO 8000-120 and specifies requirements for representation and exchange of information about accuracy of master data that consists of characteristic data. NOTE 1 ISO 8000-110 specifies that such data be represented as property values. ISO 8000-120 provides additional requirements for p
23、roperty values when data provenance information needs to be captured. 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 data accuracy information. NOTE 2 This is done in other standards that reference
24、this part of ISO 8000, e.g. ISO/TS 22745-40. The following are within the scope of this part of ISO 8000: requirements for capture and exchange of data accuracy information in the form of statements and assertions of data accuracy; conceptual data model for data accuracy information in the form of s
25、tatements and assertions of data accuracy. The following are outside the scope of this part of ISO 8000: requirements for data accuracy; NOTE 3 The requirements for data accuracy depend on many factors, e.g. the kind of data, how the data are being used, industry, and needs of the partners exchangin
26、g the data. It is not possible to state general requirements for data accuracy. exchange format for data accuracy information; scheme for registering and resolving organization identifiers and person identifiers; accuracy of data that are not characteristic data represented as property values; synta
27、x 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. 2 Normative references The following referenced documents are indispensable for t

30、ensible Markup Language 5 General A data provider may declare the accuracy of data through either a statement (see Clause 7) or an assertion (see Clause 8). 6 Accuracy data model 6.1 Referenced types and entities The following types and entities are used by the accuracy model: ISO_6523_identifier, d
31、efined in ISO 8000-120; date_and_time, defined in ISO 8000-120; property_value_assignment, defined in ISO 8000-120. 6.2 Diagram The UML class diagram for the accuracy model is given in Figure 1. Figure 1 UML class diagram for accuracy model2 ISO 2016 All rights reserved ISO 8000-130:2016(E) NOTE The
32、 entity property_value_assignment is the intersection point between this data model and the target data model: the model of data for which accuracy information is to be recorded. When the data model in Clause 6 is integrated with the target data model, this entity needs to be replaced with the appro
33、priate entity from the target data model. 6.3 completeness_event An accuracy_event is an event for which data accuracy information is recorded. Attribute definitions: details: the details of the accuracy_event.property NOTE 1 This could include the text of the statement or assertion of accuracy. eve
34、nt_type: the kind of accuracy_event The value shall be one of the following: statement: a statement of accuracy was provided for the property value; assertion: an assertion of accuracy was provided for the property value. method: accuracy_method used to record the accuracy for the accuracy_event. or
35、ganization_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 the organization to t
36、he person who performed the event. NOTE 2 The identifier need only be unique within the organization. NOTE 3 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 accuracy_event has as its method zero, one, or
37、many accuracy_method objects. Each accuracy_ method is the method for exactly one accuracy_event. Each accuracy_event records the accuracy for exactly one property_value_assignment. Each property_ value_assignment has its accuracy recorded by one or many accuracy_event objects. 6.4 accuracy_method A
38、n accuracy_method is method used to record accuracy. EXAMPLE By percent, by real number between 0 to 1,0, by qualitative statement (excellent, good, mediocre, bad). Attribute definitions: description: human-readable string that characterizes the accuracy_method. name: word or phrase by which the acc
39、uracy_method is known. Assertions: Each accuracy_method is the method for exactly one accuracy_event. Each accuracy_event has as its method zero, one, or many accuracy_method objects. ISO 2016 All rights reserved 3 ISO 8000-130:2016(E) 7 Statement of data accuracy A statement of data accuracy is a s
40、tatement of fact that enables the recipient to make a judgement as to whether the data meets the recipients data accuracy requirements. A statement of data accuracy may include: the process that generated the data; NOTE 1 This could include: process steps; environment in which the process was execut
41、ed; equipment used; calibration data. EXAMPLE 1 ISO 10303-49 contains a data model for process. EXAMPLE 2 ISO 18629 defines a neutral representation for manufacturing processes that supports automated reasoning. EXAMPLE 3 ISO/TS 14048 contains a data format for environmental data. data accuracy test

EXAMPLE 5 The X12 863 transaction set can be used to exchange test results. known inaccuracies. 8 Assertion of data accuracy An assertion of data accuracy is a declaration that a property va
43、lue meets some objective measure of data accuracy. An assertion of data accuracy shall be in writing. An assertion of data accuracy shall include: the measure of data accuracy that is being claimed; the claim process; the registered address for obtaining service; what the provider will do if the pro
44、perty value fails to meet the specified measure of data accuracy. NOTE This can include providing revised data, or providing monetary compensation. An assertion of data accuracy may include limitations. EXAMPLE Limitations on the length of the period for which service will be provided. These might i
45、nclude: date the assertion goes into effect; date the assertion expires.4 ISO 2016 All rights reserved ISO 8000-130:2016(E) 9 Data accuracy record The data accuracy record for a property value is the record of the ultimate derivation and passage of the property value through its various owners or cu
46、stodians. The data accuracy 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 accuracy record is included in the XML structure that represents property value. Coded:.ABC Company ass
47、erts that this data is accurate.Decoded:.ABC Company asserts that this data is accurate. stored separately and referenced from the structure that represents property value. EXAMPLE 2 The following is an XML code fragment in which the data accuracy record is referenced from the XML structure that rep
48、resents property value. Coded: ISO 2016 All rights reserved 5 ISO 8000-130:2016(E) ABC Company asserts that this data is accurate.Decoded:ABC Company asserts that this data is accurate.NOTE 1 The above examples include data provenance records, since any master data message claiming conformance to th
49、is part of ISO 8000 needs to include data provenance information. See ISO 8000-120 for the requirements for the data provenance record. NOTE 2 See Annex C for an explication of the codes in the examples above. NOTE 3 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 4 In the examples above, data are given in coded form followed by decoded form for clarity. An actual mast
