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.

1. Making Sense of ISO/IEC 19788
Discussion on Part 1: Framework

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

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

4. Concept Maps
Created to help with the
comprehension of some terms

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. 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.

learning resource is called a…

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

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"

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".

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. 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
