Data quality- Part 130 : Master data: Exchange of characteristic data : Accuracy
1 Scope
This document is an optional addition to GB/T 42381.120 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 property values when data provenance information needs to be captured.
This document 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 this document, e.g. ISO/TS 22745-40.
The following are within the scope of this part of this document:
- 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 statements and assertions of data accuracy.
The following are outside the scope of this document:
- 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 exchanging 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;
- syntax of identifiers;
- resolution of identifiers.
Some of the requirements in this document can apply to exchange of data that is not master data which consists of characteristic data represented as property values.
Annex A specifies the identification of this document in the information system.
Annex B gives the information to support implementations.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 8000-2 apply.
4 Abbreviated terms
UML: Unified Modeling Language
XML: Extensible 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, defined 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.
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 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 appropriate entity from the target data model.
6.3 accuracy_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.
event_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.
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 the organization to the 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 document.
when: the point in time at which the event took place.
Assertions:
Each accuracy_event has as its method zero, one, or 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
An 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 accuracy_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.
