Overview
ISO/IEC 19788-2:2011/Amd 1:2016 introduces an important amendment to Part 2 of the ISO/IEC 19788 standard, which addresses metadata for learning resources in the field of information technology, learning, education, and training. This amendment focuses specifically on supporting non-literal content value data elements within the established Dublin Core elements. By allowing for richer, non-linguistic metadata values-typically denoted as object references such as URIs-the amendment improves the granularity, interoperability, and precision of metadata associated with educational content.
Key Topics
-
Non-Literal Content Value Data Elements:
- Provides specifications for data elements where values are not limited to text literals but can reference external resources (e.g., people, organizations, structured vocabularies).
- Supports accurate linking between metadata and authoritative external sources, such as DBpedia or controlled vocabularies.
-
Extension of Dublin Core Elements:
- Complements the classic Dublin Core elements (e.g., creator, subject, description, publisher) by introducing non-literal property variants.
- Each non-literal element serves as a subproperty aligning with both DC and DCMI recommendations, promoting global interoperability.
-
Resource Classes:
- Defines resource classes such as Person and Rights Statement, enabling precise referencing of entities and rights information.
- Aligns resource class taxonomy across English, French, and Russian for multilingual metadata support.
-
Data Element Specification (DES):
- Amends existing data element specifications to support object properties, facilitating richer semantic relationships between learning resources and external entities.
- Adds technical adjustments like renaming "Range" to "Codomain" for precision in terminology.
Applications
-
Educational Metadata Management:
- Enhances metadata records for digital learning objects, e-learning modules, and open educational resources by supporting links to authoritative data sources.
- Supports more effective resource discovery, aggregation, and reuse in digital repositories and learning management systems.
-
Semantic Web and Linked Data:
- By providing for URIs and object properties, the standard fosters alignment with Semantic Web technologies, enabling more robust linked data applications in education.
-
Organizational and Legal Interoperability:
- Through improved handling of rights and contributor information (e.g., referencing Creative Commons or WIPO standards), organizations can better manage intellectual property and attribution in digital learning environments.
-
Multilingual and Cross-border Deployments:
- The explicit mapping of metadata property and resource class names across languages supports implementation in diverse educational contexts.
Related Standards
For comprehensive implementation and interoperability, consider referencing these related standards:
- ISO/IEC 19788-1: Framework for learning resource metadata.
- ISO 15836: The core Dublin Core metadata standard.
- Additional parts of ISO/IEC 19788: Covering technical, educational, distribution, and person-related elements.
- Creative Commons and WIPO conventions: For best practices in intellectual property rights within learning resource metadata.
Practical Value
Implementing ISO/IEC 19788-2:2011/Amd 1:2016 delivers key benefits for organizations and platforms involved in education technology and digital content management:
- Enables precise and automated semantic linking between metadata and authoritative sources.
- Facilitates the creation of detailed, interoperable metadata records that support discovery in global and multilingual contexts.
- Promotes adoption of open linked data standards in learning resource metadata, improving resource portability and accessibility.
- Ensures consistent handling of rights, contributors, and resource relations for compliance and legal clarity.
By leveraging these enhancements, education providers, repository managers, and system vendors can maximize the utility, discoverability, and relevance of digital learning materials for end users worldwide.
