CSA ISO/IEC 13249-2:04 (R2019)

CSA Preface Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT, Canadians serve as the Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T). This Standard supersedes CAN/CSA-ISO/IEC 13249-2:02 (adoption of ISO/IEC 13249-2:2000). This International Standard was reviewed by the CSA TCIT under the jurisdiction of the Strategic Steering Committee on Information Technology and deemed acceptable for use in Canada. (A committee membership list is available on request from the CSA Project Manager.) From time to time, ISO/IEC may publish addenda, corrigenda, etc. The CSA TCIT will review these documents for approval and publication. For a listing, refer to the CSA Information Products catalogue or CSA Info Update or contact a CSA Sales representative. This Standard has been formally approved as a National Standard of Canada by the Standards Council of Canada. Scope This part of ISO/IEC 13249: a) introduces the Full-Text part of ISO/IEC 13249 (all parts); b) gives the references necessary for this part of ISO/IEC 13249; c) defines notations and conventions specific to this part of ISO/IEC 13249; d) defines concepts specific to this part of ISO/IEC 13249; e) defines the full-text user-defined types and their associated routines. The full-text user-defined types defined in this part of ISO/IEC 13249 adhere to the following. A full-text user-defined type is generic to text handling. It addresses the need to search and retrieve information based on aspects of full-text data using patterns such as words, phrases, proximity expansion, fuzzy expansion, and thesaurus based expansions. It also addresses the need to construct such search patterns for text identification facilities and text ranking facilities. A full-text user-defined type does not redefine the database language SQL directly or in combination with another full-text data type. An implementation of this part of ISO/IEC 13249 may exist in environments that also support information and content management, decision support, data mining, and data warehousing systems. Application areas addressed by implementations of this part of ISO/IEC 13249 include, but are not restricted to, library, newspaper, multimedia, and scientific research applications.
