24、 the metadata elements required to describe a learning resource, e.g. as a metadata learning resource (MLR) record, and (2) the search, discovery, acquisition, evaluation, and use of learning resources, for example, by learners, instructors, or automated software processes. This International Standa
25、rd is modularly structured with all its parts corresponding to a specified set of user requirements for the 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 focuse
26、d on technical perspectives, pedagogical aspects, availability and intellectual property aspects, bindings, 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 rec
27、ord is defined as a “specified set of data elements describing a learning resource and resources directly related to that learning resource” (see ISO/IEC 197881:2011, 3.24).

28、 training Metadata for learning resources Part 8: Data elements for MLR records 1 Scope 1.1 Scope of MLR multipart standard The primary purpose of this International Standard is to specify metadata elements and their attributes for the description of learning resources. This includes the rules gover
29、ning the identification of data elements and the specification of their attributes. This International Standard provides data elements for the description of learning resources and resources directly related to learning resources. This International Standard provides principles, rules, and structure
30、s for the specification of the description of a learning resource. It also identifies and specifies the attributes 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 mul
31、tilingual and cultural adaptability requirements from a global perspective. ISO/IEC 197881 is information technology 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 I
32、SO/IEC 19788 This part of ISO/IEC 19788 provides data elements for the description of MLR records: sets of data elements describing a learning resource and resources directly related to that learning resource, e.g. persons (authors, contributors), annotations, learning activities, metadata records,
33、etc. It can also be used to keep track of the record editing process including global metadata author identification, 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
34、ISO/IEC 19788 or other standards to provide the description of a learning resource and of related entities needed for that 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 harves

While URIs are sequence of characters chosen from a limited subset of USASC
39、II, IRIs may contain characters from the Universal Character Set such as Chinese, Japanese, Korean, or Cyrillic characters. Note 2 to entry: A mapping from IRIs to URIs is defined in RFC 3987, making it possible to use IRIs instead of URIs, where appropriate, to identify resources. SOURCE: Adapted f
