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 part of ISO/IEC 13250 defines an XML-based interchange syntax for Topic Maps, which can be used to interchange instances of the data model defined in [ISO/IEC 13250-2]. It also defines a mapping from the interchange syntax to the data model. The syntax is defined with a
RELAXING schema, and more precision is provided through the mapping to the data model, which effectively also defines the interpretation of the syntax.
