Information technology — Learning, education and training — Metadata for learning resources — Part 8: Data elements for MLR records
ISO/IEC 19788-8:2015 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. ISO/IEC 19788-8:2015 enables the storage of learning resource description in the traditional database approach and the exchange of descriptions through harvesting mechanisms.

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical
activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work. In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1.

ISO/IEC 19788-8:2015(E)
Introduction
The primary purpose of this part of ISO/IEC 19788 is to facilitate (1) the description of a learning
resource by providing a standards‑based approach to the identification and specification of 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 Standard 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 focused 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 19788‑1 to specify data elements for the description of MLR records.
An MLR record is defined as a “specified set of data elements describing a learning resource and
resources directly related to that learning resource” (see ISO/IEC 19788‑1:2011, 3.24).

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 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
1)
database approach and the exchange of descriptions through harvesting mechanisms .

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.
