MLR data element specification (DES) identifier. For example, ISO_IEC_19788-2:2011::DES0100 tells us that this DES can be found in part 2 of the standard and DES0100 is the data element used to identify the title of the learning resource. Finally, the object can be a literal (in this example, the book title) or a resource class (a set of accepted values, such as a list of terms identifiers from a controlled vocabulary list). Computers can easily connect and query linked data structured information. For example, a teacher wishing to annotate a learning resource may do it a single RDFa triple. A repository service could gather all the information about a given learning resource from a wide variety of external sources, providing much richer information than a single provider record. Parts description Part 1: Framework Provides principles, rules and structures for the specification of the description of a learning resource Part 2: Dublin Core elements Provides a based level made of the 15 data element set for the description of learning resources, from the ISO 15836:2009 The Dublin Core metadata element set, using the framework provided in Part 1. Part 3: Basic application profile Specifies, through adding constraints to the use of some data elements, how the ISO/IEC 19788-2 element set can be used as a starting point for adopting the ISO/IEC 19788 standard. Part 3 promotes interoperability among repositories. It is expected that users communities will enhance this application profile by adding data elements from other authorities such as IEEE-LOM and Dublin Core extension and by adding vocabulary constrains. Future editions of this part will likely include additional data element from Parts 4 and beyond such as Technical or Educational data elements. Part 4: Technical elements Provides information in the form of metadata elements about conditions pertaining to the technical requirements, location, and size information Part 5: Educational elements Provides an extensive set of data elements describing the intended or actual use of learning resources across various jurisdictional, cultural and linguistic settings. The description of pedagogical use of a learning resource includes annotations, contributions, curriculum, educational outcome, audience and learning activity. Part 7: Bindings Part 7 provides RDF mappings of the different MLR entities introduced in the MLR framework: Data element specifications, resource classes, data elements, application profiles, MLR records and data element group specifications. It also provides an OWL 2 DL ontology for the resource classes and data element specifications.
