22、IEC 19778-1:2015ISO/IEC 19778-1:2015(E) Introduction Many activities in the field of learning, 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

23、 seconds to entire human generations. For example, a question posed via text messaging or email 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 col

24、laborative event is initiated by one participant, is usually received by several other participants, 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 communic

25、ative forms and contents. The International Standards on collaborative technology for learning, 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.

26、 This subset of activities is characterized by: information exchange in small or medium-sized collaborative 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

27、 place through the use of communication technology, using either a single, well-defined collaborative 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 sec

28、onds to hours); the exchange of relatively small information chunks (ranging between a single word 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 ab

29、ove) tends to be highly context-dependent or -sensitive; important contextual information presented 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 th

30、ree parts: Part 1: Collaborative workplace data model provides a representation format for Data 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 st

31、ructure and the Data Model Elements for the technical infrastructure of a collaborative workplace. 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 collab

33、orative environment and a particular collaborative group. While the physical entity collaborative workplace contains its collaborative environment and its collaborative group, the Data Model instantiations for these physical entities (and the Data Models from which these instantiations are derived)

34、are separate data entities. The Data Models specified by ISO/IEC 19778 provide the structure and the concepts for information which supports the understanding of the application intentions of collaborative workplaces and their components, is qualified for supporting the set-up and managing of collab

35、orative workplaces, enables the specification of relationships among Data Model instantiations derived from ISO/IEC 19778 or among their Data Model Element instantiations, and enables the specification of relationships among anticipated, further Data Models or their Data Model Elements (or their ins

36、tantiations), and the Data Models or their Data Model Elements of ISO/IEC 19778 (or their instantiations). The interrelationship among a collaborative workplace and its collaborative environment and collaborative group, their associated Data Model instantiations, and the corresponding Data Models sp

37、ecified in ISO/IEC 19778 is illustrated in Figure 2.

38、O/IEC 19778 specifies a Data Model that provides general information on a collaborative workplace (in Figure 2, the outer frame to the left). A collaborative workplace comprises a technical vi ISO/IEC 2015 All rights reservedBS ISO/IEC 19778-1:2015ISO/IEC 19778-1:2015(E) infrastructure (ISO/IEC 1977

39、82, Collaborative environment) and means of defining its membership (ISO/IEC 197783, Collaborative group). As illustrated in Figure 2, it is important to distinguish among (from left to right) the physical entities of a collaborative workplace, comprising its technical infrastructure and its members

40、; the Data Model instantiations that are associated with these physical entities, and that are derived from their respective Data Models using any conforming binding; the Data Models provided by ISO/IEC 19778 and specifying the (binding-independent) rules for creating Data Model instantiations.

42、able to collaborative technologies used to support communication among learners, instructors and other participants. The implementation and communicative use of these technologies entails the creation of information related to participant groups, and to the collaborative environments, functions and

43、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 portability and reuse of this data in integrated form, and allow Data Model instantiations to be interchanged, stored, retrieved, reused or analy

44、sed by a variety of systems. NOTE 1 A typical case of reusing a particular collaborative workplace Data Model instantiation (and its interlinked collaborative environment and collaborative group Data Model instantiations) is the automated set-up of new collaborative workplaces by using the specifica

45、tions in the Data Model instantiations as templates. NOTE 2 The reason for providing the specification for a collaborative workplace using several Data Models and their instantiations is to provide flexibility in the further development of these standards in future editions. By providing optional re

46、ferences to potential further specifications or standards, this approach goes far beyond the parts of ISO/IEC 19778 and the limited number of information elements provided by them. 1.1.2 This part of ISO/IEC 19778 This part of ISO/IEC 19778 specifies a table-based approach for defining Data Models.

47、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 and ISO/IEC 19778-3 to define the related components of the collaborative environment (ISO/IEC 19778-2) and the collaborative group (ISO/IEC

48、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 Model Elements and their interrelationships that enable the creation of collaborative workplace Data Model instantiations. Any conforming co

49、llaborative workplace Data Model instantiation describes or specifies a particular collaborative workplace with which it is associated. NOTE 2 How the association of 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).
