National bodies that are members of ISO or IEC participate in the development of In

13、ternational 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 liai

14、son 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

15、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 element

19、is second edition cancels and replaces the first edition (ISO/IEC 19778-3:2008), 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: P

20、art 1: Collaborative workplace data model Part 2: Collaborative environment data model Part 3: Collaborative group data modeliv ISO/IEC 2015 All rights reservedBS ISO/IEC 19778-3:2015ISO/IEC 19778-3:2015(E)IntroductionISO/IEC 19778 provides Data Models for specifying collaborative workplaces and the

21、ir 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 provid

22、es 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 collaborati

23、ve 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-

24、span of the collaborative workplace) to assign participants to these role holders.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 composition of a collaborative group in terms of roles and role h

25、olders (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

26、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

27、 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 a

28、lready 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

29、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 f

30、lexible 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. ISO/IEC 2015 All rights reserved vBS ISO/IEC 19778-3:2015ISO/IEC 19778-3:2015(E)Figure 1 Composing roles, declaring role holders,

31、 and assigning participants in this part of ISO/IEC 19778In 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 spec

32、ified 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 “poten

33、tial 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

34、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,

35、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 i

36、nstantiation 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

37、 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 refer

38、ences 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 an

39、d 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 vi ISO/IEC 2015 All rights reservedBS ISO/IEC 19778-3:2015ISO/IEC 19778-3:2015(E)reflected by future editions of this part of

41、1 Scope1.1 Statement of scopeThis 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)

42、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 ident

43、ified, 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

44、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 addressedIn future editions of this part of ISO/IEC 19778, th

45、e 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 th

46、is 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 addr

47、essed in future editions of this part of ISO/IEC 19778.1.3 Excluded subjects and aspectsSubjects 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 following: the detailed specification of roles or r

48、ole 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 assignin

49、g 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).INTERNATIONAL STANDARD ISO/IEC 19
