ISO 8000–2, Data quality — Part 2: Vocabulary 3? Terms? and? definitions For the purposes of this document, the terms and definitions given in ISO 8000–2 and the following apply. 3.1 data reinterpretable representation of information in a formalized manner suitable for communication, interpretation, or processing [SOURCE: ISO/IEC 2382:2015, 2121272, modified — Notes to entry have been removed.] 3.2 entity concrete or abstract thing in the domain under consideration [SOURCE: ISO 19439:2006, 3.29, modified — The word “any” has been removed at the start of the definition.] 3.3 information knowledge concerning objects, such as facts, events, things, processes, or ideas, including concepts, that within a certain context has a particular meaning [SOURCE: ISO/IEC 2382:2015, 2121271, modified — Field of application and notes to entry have been removed.] 3.4 metadata data that defines and describes other data [SOURCE: ISO/IEC 11179-1:2004, 3.2.16]
4 Fundamental concepts An information system is a designed system that collects, stores, processes, and distributes information about the state of a domain. The information is represented and formalized in the system as data, and presented through user interfaces. NOTE 1 For an explanation of states of domains, see Reference [13]. The main purpose of this part of ISO 8000 is to provide a foundation for measuring information and data quality. Information and data quality is defined and measured according to the following categories: — syntactic quality, which is the degree to which data conforms to its specified syntax, i.e. requirements stated by the metadata; — semantic quality, which is the degree to which data corresponds to what it represents; — pragmatic quality, which is the degree to which data is found suitable and worthwhile for a particular purpose. Measuring syntactic and semantic quality is performed through a verification process, while measuring pragmatic quality is performed through a validation process. When measuring a physical object, the measurements can be described as the dimensions length, width and height. If the object is a cylinder, radius is a candidate characteristic. Establishing a useful set of characteristics pertinent to the case at hand is important in order to cater for communication of the measurements. This part of ISO 8000 offers a set of dimensions for quantifying the quality of information and data. An activity model supporting information and data quality measurement is provided in Annex D. See ISO/TS 8000–1 for the overall description and architecture of ISO 8000. NOTE 2 The planned ISO/TS 8000–3 2) is intended to further explain the architecture of ISO 8000.
