Overview
ISO/IEC 19780-1:2015 - Information technology - Learning, education and training - Collaborative technology - Collaborative learning communication - Part 1: Text-based communication - specifies a Data Model for text-based expressions used in collaborative learning contexts. The standard provides a consistent, machine-readable way to isolate and describe textual expressions (message bodies and attachments) exchanged by members of a collaborative group within a collaborative workplace. It is the second edition (minor revision) and is aligned with the collaborative workplace concepts in ISO/IEC 19778.
Key topics and technical requirements
- Expression Data Model: Defines the structure for representing a text-based expression (the expression body and any expression attachments).
- Data elements and supplemental information: Detailed elements described include identifiers and metadata such as EX_ID, EX_Title, EX_Time_Date, reference elements (EX_B-Ref, EX_A-Ref), participant role references (CG_Role_name, CG_Role_holder_IDRef), relation fields (EX_Relation, EX_Relation_type) and collaboration tool/function identifiers (CE_Tool_name, CE_Function_name).
- Overview and specification clauses: Clauses cover an overview of the model, the formal specification of the expression Data Model, and supplemental guidance for each data element.
- Conformance: Requirements for conformant implementations are included to ensure interoperability.
- Informative annexes: Use cases and a list of terms support implementation and interpretation.
Note: the standard explicitly excludes communication involving media other than text, contexts where recipients are individually identified outside the collaborative group (e.g., private whispering), and participant permissions/privacy data.
Practical applications
- Enabling interoperability between learning tools (chat, forums, discussion boards, mailing lists) and LMS integrations by providing a common data model for text messages.
- Facilitating archival, exchange and reconstruction of threaded discussions and chat logs while preserving relationships among messages.
- Supporting analytics, research and learning analytics tools that require standardized message metadata (timestamps, author role, reply relationships).
- Guiding software architects, edtech vendors and integrators when designing messaging services for collaborative learning environments.
Who should use this standard
- LMS and collaboration platform vendors implementing chat, discussion or mailing-list features.
- Developers and system integrators building interoperable educational tools.
- Educational institutions and IT teams standardizing data exchange and archival formats.
- Standards bodies and researchers working on collaborative learning communication models.
