Making Sense of ISO/IEC 19788


Published on

Initial discussion on the basic parts (framework) of the ISO/IEC 19788. Concept maps that outline the logic behing the standard. The presentation is a personal reflection an is by no means a formal presentation of the standard.

Making Sense of ISO/IEC 19788

  1. 1. Making Sense of ISO/IEC 19788 Discussion on Part 1: Framework
  2. 2. ISO/IEC 19788 • Multi-part standard prepared by subcommittee SC36 of the Joint Technical Committee ISO/IEC JTC1, Information Technology for Learning, Education and Training – Committee created to deal with the overlapping of standardization done by ISO and IEC – The standard is intended to provide compatibility with DC and LOM and also support multilingual and cultural adaptability requirements from a global perspective Source:
  3. 3. Purpose • facilitate the identification and specification of the metadata elements required to describe a learning resource by providing metadata elements and their attributes • support search, discovery, acquisition, evaluation, and use of learning resources by learners, instructors or automated software processes Source:
  4. 4. Concept Maps Created to help with the comprehension of some terms
  5. 5. Concept Map 1 • The following concept map contains the main aspects of ISO/IEC 19788 • Starting from the upper left, follow the nodes down to the lower right to get a first glimpse of the standard • In the next concept maps, additional information for each aspect is provided
  6. 6. Entity ISO/IEC 19788 describes an… …that when referenced by an identifier is considered a… Resource …which in turn can be described using a… Data Element …that belongs to a… Resource Class …that contains all the resources that have properties & behavior following the same rule or rule set. …that when used to describe a learning resource is called a… Learning Resource …that when used for learning, education and training, is called a… Metadata Element …that is defined through a… Data Element Specification Metadata Record …that is part of a… Application Profile Data Element Group Specifications …that when combined with others creates an… Application Profile Record …that is described by an… Application Profile Specification Content Value
  7. 7. Concept Map 2 • An "Entity" can be any concrete or abstract thing that exists. This can be a person, an object, an idea, an event or a process • Each entity has "Attributes" that characterize it and it also has "Attribute Values“, the value that each attribute takes • Each Entity that is referenced by a stable identifier (like a URI), is a "Resource" • A group of resources whose properties and behaviour, follow the same rule or rule set, are referred to as "Resource Class" • Resources & Resource Class are described with "Data Elements" that have their own Attributes & Attribute Values
  8. 8. Class Entity Person, object, idea, event, process attribute value value value attribute value value Resource Entity referenced by a stable identifier can be Resource Class belongs to resources that follow rule rule set OR Learning Resource domain Resource used for learning, education or training Data Element described by content value has attribute value value value attribute value value type of content valuecontent value range
  9. 9. Concept Map 3 • A Data Element, a unit of data that is, is described in a "Data Element Specification" • When the Data Element conforms to a specific rule or rule set, it is called a "Conformant Data Element“ • An aggregation of Data Elements, is called a "Data Element Group" • Their description using specific attributes and values, is called a "Data Element Group Specification“ • Each Data Element that describes a Learning Resource (resource used for learning, education and training), is called a "Metadata Element"
  10. 10. attribute value value value attribute value value Data Element Unit of data attribute value value value attribute value value Data Element Specification Data Element Data element group attribute value value value attribute value value Data Element Group Specification rule rule set OR Metadata Element
  11. 11. Concept Map 4 • When an Application Profile is used to describe a Learning Resource, following a specific rule set, then an "Application Profile Record" is created. If all the Data Elements used within the Application Profile are conformant, then the result is a "Conforming Application Profile Record".
  12. 12. Application Profile Learning Resource applied to creates Application Profile Record Learning Resource rule rule set AND following If all data elements are conformant to rules, we have a conforming AP record
  13. 13. Example of a Data Element Specification Source:
  14. 14. Resource Description Framework (RDF) • Assertions for a learning resource can be made using triples of subject, predicate and object – Subject: Identifier of a learning resource (URI) – Predicate: Identifier of the data element spec – Object: Information like a book title or a value from a pre-defined vocabulary • Resource X is described using data element Y and takes value Z
  15. 15. Parts of ISO/IEC 19788 • Part 1: Framework • Part 2: Dublin Core elements • Part 3: Basic application profile • Part 4: Technical elements • Part 5: Educational elements • Part 7: Bindings • Part 8: Data elements for MLR records • Part 9: Data elements for persons • Part 11: Migration from LOM to MLR
