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 has been formally approved, without modification, by the Technical Committee and has been approved as a National Standard of Canada by the Standards Council of Canada. Scope ISO/IEC 19788 specifies, in a rule-based manner, metadata elements and their attributes for the description of learning resources. This includes the rules governing the identification of data elements and the specification of their attributes. These metadata elements are used to form the description of a learning resource, i.e. as a metadata learning resource (MLR) record. This part of ISO/IEC 19788 provides a base-level data element set for the description of learning resources, from the ISO 15836:2009 Dublin Core metadata element set, using the framework provided in ISO/IEC 19788-1. This provides interoperability at the time of expressing existing Dublin Core records within MLR. These elements can later be combined with other descriptive elements, including those from other type 1 parts of ISO/IEC 19788 or other standards, including Dublin Core refinements and IEEE 1484.12.1-2002, in order to address more specific topics such as technical or educational information.
