National bodies that are members of ISO

14、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,

15、 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

16、 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 t

22、 education and training are collaborative in nature, involving turn-taking, statement-and-response or multi-thread discussions which, in turn, take place among participants over periods of time ranging from seconds to entire human generations. For example, a question posed via text messaging or emai

23、l might receive a response in a matter of seconds, minutes or hours; commentary on a historically-significant text might take place months, years or even generations after it has been written. A typical collaborative event is initiated by one participant, is usually received by several other partici

24、pants, refers to a previous collaborative event, and provides a response to it. Collaborative activities can be established in the widest imaginable range of circumstances, involving many different communicative forms and contents.The International Standards on collaborative technology for learning,

25、 education and training focus on a particular subset of these collaborative activities. All terms specifically defined in these International Standards are italicized throughout all parts of ISO/IEC 19778. This subset of activities is characterized by: information exchange in small or medium-sized c

26、ollaborative groups of participants (typically above two and below a few dozen) who collaborate over relatively short periods of time (typically several days to several months); information exchange taking place through the use of communication technology, using either a single, well-defined collabo

27、rative tool supporting collaborative functions, or a set of collaborative tools, organized in a collaborative environment; short intervals in establishing feedback on messages or expressions (generally seconds to hours); the exchange of relatively small information chunks (ranging between a single w

28、ord and a small number of paragraphs); a relatively high level of responsiveness among active collaborative group members; information exchanged among participants (due to a number of the factors listed above) tends to be highly context-dependent or -sensitive; important contextual information prese

29、nted by the relationship between these collaborative group members and the collaborative environment (and its subcomponents), which all together form a collaborative workplace.ISO/IEC 19778 consists of three parts: Part 1: Collaborative workplace data model provides a representation format for Data

30、Model specification, and specifies the Data Model structure and the Data Model Elements for the collaborative workplace in general. Part 2: Collaborative environment data model specifies the Data Model structure and the Data Model Elements for the technical infrastructure of a collaborative workplac

31、e. Part 3: Collaborative group data model specifies the Data Model structure and the Data Model Elements specifying and providing information for the membership of a collaborative workplace.

Any collaborative workplace represents the combination of a particular collaborative environment and a particular collaborative group. While the physical entity collaborative workplace contains its collab

33、orative environment and its collaborative group, the Data Model instantiations for these physical entities (and the Data Models from which these instantiations are derived) are separate data entities.The Data Models specified by ISO/IEC 19778 provide the structure and the concepts for information wh

36、among a collaborative workplace and its collaborative environment and collaborative group, their associated Data Model instantiations, and the corresponding Data Models specified in ISO/IEC 19778 is illustrated in Figure 2.Figure 2 The interrelationship among a collaborative workplace and its collab

41、nology Collaborative workplace Part 1: Collaborative workplace data model1 Scope1.1 Statement of scope1.1.1 ISO/IEC 19778ISO/IEC 19778 is applicable to collaborative technologies used to support communication among learners, instructors and other participants. The implementation and communicative us

42、e of these technologies entails the creation of information related to participant groups, and to the collaborative environments, functions and tools that are set up for, and used by, these groups. This part of ISO/IEC 19778:, together with its subsequent parts, defines Data Models that enable the p

43、ortability and reuse of this data in integrated form, and allow Data Model instantiations to be interchanged, stored, retrieved, reused or analysed by a variety of systems.NOTE 1 A typical case of reusing a particular collaborative workplace Data Model instantiation (and its interlinked collaborativ

44、e environment and collaborative group Data Model instantiations) is the automated set-up of new collaborative workplaces by using the specifications in the Data Model instantiations as templates.NOTE 2 The reason for providing the specification for a collaborative workplace using several Data Models

45、 and their instantiations is to provide flexibility in the further development of these standards in future editions. By providing optional references to potential further specifications or standards, this approach goes far beyond the parts of ISO/IEC 19778 and the limited number of information elem

46、ents provided by them.1.1.2 This part of ISO/IEC 19778This part of ISO/IEC 19778 specifies a table-based approach for defining Data Models. This Data Model specification is used for specifying the collaborative workplace Data Model. The same Data Model specification is also used in ISO/IEC 19778-2 a

47、nd ISO/IEC 19778-3 to define the related components of the collaborative environment (ISO/IEC 19778-2) and the collaborative group (ISO/IEC 19778-3) in separate Data Models.NOTE 1 This Data Model specification is also used in ISO/IEC 19780.The collaborative workplace Data Model specifies the Data Mo

48、del Elements and their interrelationships that enable the creation of collaborative workplace Data Model instantiations.Any conforming collaborative workplace Data Model instantiation describes or specifies a particular collaborative workplace with which it is associated.NOTE 2 How the association o

49、f a particular collaborative workplace Data Model instantiation and a particular collaborative workplace is implemented is outside the scope of this part of ISO/IEC 19778 (i.e. is dependent on the implementation of the used collaboration system).Any conforming collaborative workplace Data Model instantiation references Data Model instantiations for both a particular collaborative environment and a particular collaborative group;INTERNATIONAL STANDARD ISO/IEC 19778-1:2015(E) ISO/IEC 2015 All right
