Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical
activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work. In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for
the different types of document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent
rights. Details of any patent rights identified during the development of the document will be in the
Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information

This second edition cancels and replaces the first edition (ISO/IEC 19780-1:2008), of which it constitutes
a minor revision.

Introduction
Collaborative communication in general
Collaborative learning that is supported with information and communication technologies (ICTs)
can involve the use of a range of media, including audio (e.g. IP telephony), video (e.g. video over IP),
graphics (e.g. shared whiteboard) and text (e.g. chat, computer conferencing). Combinations of these
media (e.g. audio telegraphics) can also be used in collaborative learning activities. ISO/IEC 19780
focuses on messages and events arising in the course of collaborative learning activities, using a range
of collaborative tools and media types. ISO/IEC 19780 understands and defines these communicative
actions and events as being sent and received by participants and within environments, as these are
conceptualized and defined in ISO/IEC 19778.
This part of ISO/IEC 19780 focuses on text-based communications and messages. Future editions
or parts of ISO/IEC 19780 may address communications using other media (e.g. audio or video), or
communications independent of any particular medium. Experience and feedback deriving from
this part of ISO/IEC 19780 and from work with evolving communication media are likely to play an
important role in determining the shape and direction of this future standardization work.
In this context, “text” can be defined in terms provided by the Oxford English Dictionary: “the wording
of anything expressed; the structure formed by the words in their order; the very words, phrases, and
sentences as written.” Text is further understood here as that which can be expressed using a specified
character set (here the “coded character sets” defined in ISO 10646). The use of markup languages
derived from the specified character set used is also admissible.
Some of the most common forms of ICT-supported collaborative learning involve the exchange of
messages or text-based expressions. As defined here, text-based collaboration and communication
is characterized by relatively brief messages or “small” expression bodies (e.g. a single word to a few
paragraphs), and by relatively short time intervals between such expressions (fractions of a second
to days). The result is that content generated through this type of communication tends to be
highly context-dependent, with any one textual expression often gaining its meaning from complex
relationships to others. This makes the portability and potential reconstruction of these relationships
and of this context of great significance.
Within the general parameters described above, the length of and time intervals between discrete
communicative actions or messages can vary. Collaborative technologies and activities with the
smallest intervals between messages are often labelled “synchronous”, and tend to be associated with
the term “chat”. Those with longer intervals and more sizeable expression bodies are often labelled
“asynchronous”, and tend to be associated with terms such as “discussion” or “conferencing”. In the
terminology defined in ISO/IEC 19778, both synchronous (chat) and asynchronous (discussion)
represent particular collaborative services, composed of collaborative tools (ICQ, Windows Messenger,
etc.), which provide collaborative functions (e.g. instant messaging). These functions, in turn, contribute
to particular collaborative effects (e.g. facilitating the gradual achievement of consensus).
NOTE Italicized terms in the paragraphs above and throughout this part of ISO/IEC 19780 are defined in
Clause 3 or in ISO/IEC 19778-1.
Text-based communication in particular
This part of ISO/IEC 19780 presents a Data Model for text-based expressions.
A collaborative workplace is defined as an instantiated independent entity, consisting of the collaborative
activities of a collaborative group, which works together by means of a collaborative environment
(ISO/IEC 19778-1 to ISO/IEC 19778-3).
As these definitions indicate, collaborative workplaces are associated with two major kinds of components:
— collaborative service components;
— collaborative group components.

This part of ISO/IEC 19780 provides a Data Model to accommodate the data constituted by and
associated with text-based messages or expressions, which are exchanged among collaborative group
members within a collaborative environment.
Expressions are composed by and exchanged among collaborat
