This second edition cancels and replaces the first edition (ISO/IEC 19778-3:2008), of which it constitutes a minor revision.

21、ction 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 work

22、place: 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

23、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 holder

24、s (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 purposes of this part of ISO/IEC 19778 are the following: to provide a standardized way of defining and instantiating, as an

25、 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 wo

26、rkplace 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

27、“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

28、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

29、“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 M

30、odel 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.

31、 ISO/IEC 19778-3:2015ISO/IEC 19778-3:2015(E) 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 a

32、nd 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

33、 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

34、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

35、 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 rol

36、e 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 m

37、ethod 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

38、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 adopt

39、ers 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 vi ISO/IEC 2015 All rights r

41、nd training Collaborative technology Collaborative workplace 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

42、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 b

43、y 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 informati

44、on 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 informat

45、ion. 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 D

46、ata 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-st

47、ate 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 pr

48、ovided by further specifications or standards include the following: 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 applic

49、ations 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 in
