scope:

ISO/IEC 19778 is applicable to collaborative technologies used to support communication among learners, instructors and other participants. The implementation and communicative use of these technologies entails the creation of information related to participant groups, and to the collaborative environments, functions and tools that are set up for, and used by, these groups. This part of ISO/IEC 19778 - together with its subsequent parts - defines Data Models that enable the portability and reuse of this data in integrated form, and allow Data Model instantiations to be interchanged, stored, retrieved, reused or analysed by a variety of systems. This part of ISO/IEC 19778 specifies a table-based approach for defining Data Models. This Data Model specification is used for specifying the collaborative workplace Data Model. The same Data Model specification is also used in ISO/IEC 19778-2 and ISO/IEC 19778-3 to define the related components of the collaborative environment (ISO/IEC 19778-2) and the collaborative group (ISO/IEC 19778-3) in separate Data Models. The collaborative workplace Data Model specifies the Data Model Elements and their interrelationships that enable the creation of collaborative workplace Data Model instantiations. Any conforming collaborative workplace Data Model instantiation describes or specifies a particular collaborative workplace with which it is associated. Any conforming collaborative workplace Data Model instantiation references Data Model instantiations for both a particular collaborative environment and a particular collaborative group; provides its particular identifier that allows this Data Model instantiation to be referenced from other Data Model instantiations; NOTE 3 The ISO/IEC 19778 Data Models and Data Model or Data Model Element instantiations are referenced by ISO/IEC 19780, which provides storage formats for captured communicative contributions, along with contextual data (relationship to other contributions, time sent, authorship, etc.). provides the life-span dates-and-times for the associated collaborative workplace; may provide a name and a textual description for its associated collaborative workplace, particularly for the purpose of full-text seach for collaborative workplace Data Model instantiations.
