ANSI ISO IEC 11179-2-2000 pdf download Information technology — Specification and standardization of data elements — Part 2: Classification for data elements
1 Scope
This part of ISO/IEC 11179 provides procedures and techniques for associating data with classification schemes. Several components of data elements invite classification—components covered by ISO/IEC 11179—include object classes, properties, representations, value domains, and data element concepts, as well as data elements themselves. The procedures and techniques specified in ISO/IEC 11179-2 will enable Registration Authorities to apply classification schemes that better enable one to
analyze object classes, data element concepts, and data elements
make comparisons within the following categories: object classes, properties, representations, data elementconcepts, and data elements
reduce the variety of data element concepts and data elements
identify, describe, and define data element concepts and data elements unambiguously
assist in the analysis of data elements for the purpose of assigning registration status
address synonym and homonym problems
retrieve data element concepts and data elements from a data register
recognize relationships among data element concepts and data elements
support the unique and unambiguous identification and referencing of object classes, data element concepts,and data elements in a manner that is linguistically neutral and information technology enabled.
The preparation of ISO/IEC 11179 has also been prompted by the need for standardized data design procedures that will ensure the emergence of data elements capable of supporting electronic data interchange.
This part of ISO/IEC 11179 develops a set of principles, methods, and procedures for specifying what is needed (at a minimum) to document the association between the various components of a data element and one or more classification schemes. This includes the names, nonintelligent identifiers, definitions, and other aspects of the classification scheme and its contents. These can be captured through use of a set of attributes. Particular attributes are specified in this part of ISO/IEC 11179, along with a structure for the contents of these attributes. Users may extend the set of attributes as necessary. Additional information may accompany a taxonomy or ontology; for example, to provide a suggested set of qualifiers that could be applied to the object class, property, or representation taxa to more fully qualify the classification of the particular data element. This part of ISO/IEC 11179 builds upon and utilizes the basic attributes specified in ISO/IEC 11179-3 of ISO/IEC 11179.
