20、ion (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 Part 2: Co

21、llaborative environment data model Part 3: Collaborative group data modeliv ISO/IEC 2015 All rights reservedBS ISO/IEC 19778-2:2015ISO/IEC 19778-2:2015(E) Introduction ISO/IEC 19778 provides Data Models for specifying collaborative workplaces and their components. ISO/IEC 19778-1 provides general in

22、formation 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

23、 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

24、 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 collaborat

25、ive 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 entiti

26、es 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 envi

27、ronment. 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 ar

28、e 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

29、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 int

30、ention 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 multi

31、part standard that represents prospective technology. Figure 1 illustrates how this is achieved. ISO/IEC 2015 All rights reserved vBS ISO/IEC 19778-2:2015ISO/IEC 19778-2:2015(E) Figure 1 Composing collaborative tools and declaring collaborative functions in this part of ISO/IEC 19778 In this part of

32、 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 fu

33、rther 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 pro

34、perties of collaborative tools and collaborative functions 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. Where the need for broader interoperability ex

35、ists, external “specifications or standards” are required. They would at least define a set of collaborative tools or collaborative functions, provide names for them, and describe their properties. Of course, such “specifications or standards” could be very simple and general. However, they could be

36、 highly sophisticated and detailed as well. Where a collaborative environment Data Model instantiation makes use of such an external “specification or standard”, it references it and adopts the names for collaborative tools or collaborative functions as shown in Figure 1. Using this first edition of

37、 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 collaborative tools or collaborative functions. It is intended as a step towards broader harmonization of collaborative tools or c

38、ollaborative functions with respect to their specification and naming. This expected progress in harmonization will be reflected by future editions of this part of ISO/IEC 19778, while todays users can employ this first edition instantly.vi ISO/IEC 2015 All rights reservedBS ISO/IEC 19778-2:2015INTE

40、ironment. The collaborative environment Data Model composes collaborative tools and declares their collaborative functions by specifying their names. These names can be used as references to collaborative tools and collaborative functions specified in detail by further specifications or standards. W

41、here no such specifications or standards are available or identified, the provision of descriptions for human interpretation may support harmonized use of these names. 1.2 Subjects and aspects not currently addressed In future editions of this part of ISO/IEC 19778, extended support for adapting col

42、laborative environments to preferences and needs of participants may be provided. Such support can be gained by prioritizing the collaborative effects (defining which collaborative effects are intended to be supported) in contrast to the collaborative tools and collaborative functions (defining by w

43、hich technical provisions the intended collaborative effects are supported). 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 following: the detailed spec

44、ification of collaborative tools or collaborative functions (such specification is left to further specifications or standards and means service component harmonization which is excluded from this part of ISO/IEC 19778); the detailed specification of collaborative effects (such specification is left

45、 to further specifications or standards and addresses application modelling which is excluded from this part of ISO/IEC 19778); the specification of methods for integrating collaborative tools or collaborative functions into services (as this affects service modelling which is excluded from this par

46、t of ISO/IEC 19778). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
