Information technology — Learning, education and training — Collaborative technology — Collaborative workplace — Part 3: Collaborative group data model
ISO/IEC 19778-3:2008 specifies the Data Model for a collaborative group. The collaborative group Data Model composes roles which can be played by the participants of a collaborative group, declares the intended role holders (positions for playing a particular role) for each role, and (at least during the life-span of the collaborative workplace) assigns participants to these role holders. The role names may be used as references to roles specified in detail by further specifications or standards. Where no such specifications or standards are available or identified, the provision of descriptions for human interpretation may support harmonized use of these names. Provided participant identifiers may be used as references to detailed participant information which may be specified in a provided user management system.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
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.
ISO/IEC 19778-3 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 36, Information technology for learning, education and training.
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
⎯ Part 2: Collaborative environment data model
⎯ Part 3: Collaborative group 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. ISO/IEC 19778-2 provides the Data Model for the
collaborative environment and specifies information related to the service aspects of a collaborative
workplace. This part of ISO/IEC 19778 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 roles which can
be played by the participants of a collaborative group, to declare the intended role holders (positions for
playing a particular role) for each role, and (at least during the life-span of the collaborative workplace) to
assign participants to these role holders.
The purpose of this part of ISO/IEC 19778 is:
⎯ to provide a standardized way of defining and instantiating, as an independent entity, the composition of a
collaborative group in terms of roles and role holders (this is done by associating this composition with a
collaborative group identifier unique within a particular domain or application context);
⎯ to specify the membership requirements of a collaborative workplace for the purpose of set-up,
employment, management, administration, and evaluation of its collaborative group.
The detailed specification of the roles is not provided in this part of ISO/IEC 19778; however, it may be linked
to the collaborative group 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.)
No reference to detailed specification of participants is provided in this part of ISO/IEC 19778 as multiple-
purpose user management provisions are currently already in place and will be used.
Linkages to "potential further specifications or standards" are constituted by employing a "source/value"
approach, where the value (e.g. the name of a role) is taken from a "source", a specification or standard,
which declares the names and specifies the details of roles. 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 19778-3 is a part of a multipart standard
that represents prospective technology. Figure 1 illustrates how this is achieved.

Figure 1 — Composing roles, declaring role holders, and assigning participants
in this part of ISO/IEC 19778
In this part of ISO/IEC 19778, "composing roles" and "assigning participants to role holders" are generally
performed by specifying names of roles and identifiers of participants. Further information on these roles and
participants may be specified in "potential further specifications or standards" or in user management
provisions 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" or provisions. If no
"potential further specifications or standards" or participant identification provisions are used, the names and
properties of roles and the identifiers of participants need to be consistently known in the user community.
This, however, also means that the interoperability of Data Model instantiations of this kind is limited to this
"harmonized" user community.
It should be noted that, where no participants are assigned to the role holders, the respective collaborative
group Data Model instantiation can be reused as a template for setting up further collaborative groups of the
same dedication. Also, due to the provision of role holder identifiers, anonymizing a collaborative group Data
Model instantiation by removing the assigned participant identifiers does not affect the differentiation between
role holders. This is important in cases where role holders of the collaborative group Data Model instantiation
are referenced by other data objects.
Where the need for broader interoperability exists, external "specifications or standards" are required. They
would at least define a set of roles or a method for identifying participants and information on them, provide
names for roles, and describe their properties. Of course, "specifications or standards" for roles could be very
simple and general. However, they could be highly sophisticated and detailed as well. Where a collaborative
group Data Model instantiation makes use of such an external "specification or standard" for roles, it
references it and adopts the role names as shown in Figure 1.
Using this first edition of this part of ISO/IEC 19778 provides utmost flexibility at the risk of a low level of
interoperability. It allows adopters to experiment with diverse specifications for roles or methods for identifying
participants and providing information on them. It is intended as a step towards broader harmonization of such
specifications or provisions. This expected progress in harmonization will be reflected by future editions of this
part of ISO/IEC 19778, while today's users can employ this first edition instantly.

Part 3:
Collaborative group data model
1 Scope
1.1 Statement of scope
This part of ISO/IEC 19778 specifies the Data Model for a collaborative group.
The collaborative group Data Model composes roles which can be played by the participants of a collaborative
group, declares the intended role holders (positions for playing a particular role) for each role, and (at least
during the life-span of the collaborative workplace) assigns participants to these role holders. The role names
may be used as references to roles specified in detail by further specifications or standards. Where no such
specifications or standards are available or identified, the provision of descriptions for human interpretation
may support harmonized use of these names. Provided participant identifiers may be used as references to
detailed participant information which may be specified in a provided user management system.
NOTE There is a risk of improper access and misuse of personal and private data facilitated by use of the
collaborative group Data Model. It is the responsibility of the implementer to ensure proper use of any involved personal
information.
1.2 Subjects and aspects not currently addressed
In future editions of this part of ISO/IEC 19778, the identification of participant types referring to a harmonized
or standardized participant typology may be provided. Such a provision would upgrade the value of
anonymized collaborative group Data Model instantiations for being reused as templates.
Currently, the collaborative groups specified by this Data Model are static. Participants may not be online all
the time; in a collaborative group, private discussions may occur; participants may leave the collaborative
group during the life-state of the collaborative workplace. It is not yet clear to which degree such aspects can
and should be addressed in future editions of this part of ISO/IEC 19778.
1.3 Excluded subjects and aspects
Subjects and aspects not provided by this part of ISO/IEC 19778, but which it is anticipated will be provided by
further specifications or standards include:
⎯ the detailed specification of roles or role typologies in the context of learning, education and training (such
specification is reserved for further specifications or standards; it may be specific for particular domains of
applications in this field; such specifications are excluded from this part of ISO/IEC 19778);
⎯ methods for assigning collaborative tools or collaborative functions of a collaborative workplace to
participants in particular roles (such methods mean optimization for mapping capabilities and
requirements of technical means to capabilities and preferences of participants; such methods are
excluded from this part of ISO/IEC 19778);
⎯ the detailed specification of participant information (such specification is reserved for further specifications
or standards and is excluded from this part of ISO/IEC 19778).
