National bodies that are members
15、 of ISO 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 organi
16、zations, 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 mainten
17、ance are 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
18、 drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introductio

23、onThe primary purpose of this part of ISO/IEC 19788 is to facilitate (1) the description of a learning resource by providing a standardsbased approach to the identification and specification of the metadata elements required to describe a learning resource, e.g. as a metadata learning resource (MLR)
24、 record, and (2) the search, discovery, acquisition, evaluation, and use of learning resources, for example, by learners, instructors, or automated software processes.This International Standard is modularly structured with all its parts corresponding to a specified set of user requirements for the
25、identification and specification of metadata elements having a particular focus and intended use in the description of a learning resource. This includes categories of metadata elements focused on technical perspectives, pedagogical aspects, availability and intellectual property aspects, bindings,
26、etc.This part of ISO/IEC 19788 uses the data element specification (DES) model and framework provided in ISO/IEC 197881 to specify data elements for the description of MLR records.An MLR record is defined as a “specified set of data elements describing a learning resource and resources directly rela
27、ted to that learning resource” (see ISO/IEC 197881:2011, 3.24).

28、rt standardThe primary purpose of this International Standard is to specify metadata elements and their attributes for the description of learning resources. This includes the rules governing the identification of data elements and the specification of their attributes.This International Standard pr
29、ovides data elements for the description of learning resources and resources directly related to learning resources.This International Standard provides principles, rules, and structures for the specification of the description of a learning resource. It also identifies and specifies the attributes
30、of a data element, as well as the rules governing their use. The key principles stated in ISO/IEC 197881 are informed by a user requirementsdriven context with the aim of supporting multilingual and cultural adaptability requirements from a global perspective.ISO/IEC 197881 is information technology
31、 neutral and defines a set of common approaches, i.e. methodologies and constructs, which apply to the development of the subsequent parts of ISO/IEC 19788.1.2 Scope of this part of ISO/IEC 19788This part of ISO/IEC 19788 provides data elements for the description of MLR records: sets of data elemen
32、ts describing a learning resource and resources directly related to that learning resource, e.g. persons (authors, contributors), annotations, learning activities, metadata records, etc. It can also be used to keep track of the record editing process including global metadata author identification,
33、last record update, and application profile used for the description of a learning resource.These elements can later be combined with other descriptive elements from other parts of ISO/IEC 19788 or other standards to provide the description of a learning resource and of related entities needed for t
34、hat description.This part of ISO/IEC 19788 enables the storage of learning resource description in the traditional database approach and the exchange of descriptions through harvesting mechanisms1).2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this
