BS ISO IEC 19788-8 pdf download.Information technology — Learning, education and training — Metadata for learning resources
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 governing 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 structures 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 19788‑1 are informed by a user requirements‑driven context with the aim of supporting multilingual and cultural adaptability requirements from a global perspective. ISO/IEC 19788‑1 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 ISO/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, 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 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 harvesting mechanisms .The previous version of an MLR record describing a given learning resource and related resources is distinct from the MLR record under consideration. Using the property ”previous version”, one can keep track of the sequence of modifications to the description of a learning resource and related resources.
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO/IEC 19788-1 and the following apply. 3.1 internationalized resource identifier IRI sequence of characters from the Universal Character Set (see ISO 10646) constructed according to the syntax rules provided in RFC 3987 Note 1 to entry: IRIs are generalization of URIs (ISO/IEC 19788‑1:2011, 3.36). While URIs are sequence of characters chosen from a limited subset of US‑ASCII, 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 from Internationalized Resource Identifiers (IRIs). IETF RFC 3987. Available from: http://tools.ietf.org/pdf/rfc3987.pdf] 3.2 mutable MLR record container for an MLR record (ISO/IEC 19788-1:2011, 3.24) describing a given learning resource (ISO/IEC 19788‑1:2011, 3.20) and resources directly related to that learning resource Note 1 to entry: An MLR record (ISO/IEC 19788‑1:2011, 3.24) is non‑mutable. Addition or deletion of data elements (ISO/IEC 19788‑1:2011, 3.11) to the data element set or modification of any data element belonging to the data element set makes it a different MLR record. Note 2 to entry: Unlike the situation for an MLR record, the state (content) of a mutable MLR record can change over time while still describing a given learning resource and resources related to it.
