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.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/IEC JTC 1, Information technology, Subcommittee
SC 36, Information technology for learning, education and training.
This second edition cancels and replaces the first edition (ISO/IEC 19778-2:2008), of which it constitutes
a minor revision.
ISO/IEC 19778 consists of the following parts, under the general title Information technology — Learning,
education and training — Collaborative technology — Collaborative workplace:
— Part 1: Collaborative workplace data model

Introduction
ISO/IEC 19778 provides Data Models for specifying collaborative workplaces and their components.
ISO/IEC 19778-1 provides general information for all parts, and specifies a Data Model which, by
reference, composes the Data Model instantiations of the two main components of a collaborative
workplace: the collaborative environment and the collaborative group. This part of ISO/IEC 19778 provides
the Data Model for the collaborative environment and specifies information related to the service aspects
of a collaborative workplace. ISO/IEC 19778-3 provides the Data Model for the collaborative group and
specifies information related to the roles and the membership of a collaborative workplace.
The main accomplishment of this part of ISO/IEC 19778 is to specify the composition of the collaborative
tools which are integrated in the collaborative service(s) of a collaborative workplace. As collaborative
tools frequently provide several collaborative functions, these collaborative functions are also identified
in the collaborative environment Data Model.
The purposes of this part of ISO/IEC 19778 are the following:
— to provide a standardized way of defining and instantiating, as an independent entity, the
service(s) and associated entities of a collaborative workplace (this is done by associating these
services and entities with a collaborative environment identifier unique within a particular domain
or application context);
— to specify the technical and infrastructural requirements of a collaborative workplace for the purpose
of set-up, employment, management, administration, and evaluation of its collaborative environment.
The detailed specification of the collaborative tools and their collaborative functions is not provided
in this part of ISO/IEC 19778; however, it may be linked to the collaborative environment Data Model
instantiations by referring to “potential further specifications or standards” that are not identified
and possibly do not yet even exist. (One of the intentions of this part of ISO/IEC 19778 is to encourage
adopters to develop and harmonize such specifications.)
Linkages to “potential further specifications or standards” are constituted by employing a “source/value”
approach, where the value (e.g. the name of a collaborative tool or collaborative function) is taken from a
“source”, a specification or standard, which declares the names and specifies the details of collaborative
tools or collaborative functions. The “source” itself is specified by reference, using a URL. The intention
of this “source/value” approach is to provide a simple method for linking developing specifications or
standards to the Data Model of this part of ISO/IEC 19778 without needing to identify them beforehand.
This highly flexible method reflects the fact that ISO/IEC 19778-2 is a part of a multipart standard that
represents prospective technology. Figure 1 illustrates how this is achieved.

Figure 1 — Composing collaborative tools and declaring collaborative functions
in this part of ISO/IEC 19778
In this part of ISO/IEC 19778, “composing collaborative tools” and “declaring their collaborative
functions” are generally performed by specifying names of collaborative tools and collaborative
functions. Further information on these collaborative tools and collaborative functions may be specified
in “potential further specifications or standards” which are not included in this part of ISO/IEC 19778.
The adopters of this part of ISO/IEC 19778 may decide whether or not to use such “potential further
specifications or standards”. If no “potential further specifications or standards” are used, the names
and properties of collaborative tools and collaborative functions need to be consistently known in the
user community. This, however, also means that the interoperability
