Overview
ISO/IEC 19788-2:2011 - part of the Metadata for Learning Resources (MLR) family - defines a base-level set of metadata data element specifications derived from the Dublin Core (ISO 15836:2009) element set and expressed within the ISO/IEC 19788 framework. Its purpose is to enable consistent, standards-based description of learning resources to improve discovery, exchange and automated processing across learning repositories, LMSs and digital libraries.
Key topics and technical requirements
- Dublin Core elements cast into MLR: Title, Creator, Subject, Description, Publisher, Contributor, Date, Type, Format, Identifier, Source, Language, Relation, Coverage and Rights are specified as Data Element Specifications (DES0100…DES1500).
- Framework compliance: Data elements use the structural model and attribute rules defined in ISO/IEC 19788‑1:2011 (framework), including domains (Resource / Learning Resource) and ranges (e.g., MLR String).
- Content value rules and predefined rule sets: Elements reference rule sets such as PRS0001 (MLR String) and PRS0002 (Date) to standardize representation and encoding of values.
- Resource classes and vocabularies: Defines the resource classes (“Resource”, “Learning Resource”) and normative vocabularies to promote consistency and controlled terminology.
- Interoperability focus: Intended to permit existing Dublin Core records to be expressed as MLR records so they can be combined with other ISO/IEC 19788 data elements or domain-specific extensions.
Practical applications
- Improve metadata interoperability across learning repositories and institutional collections by mapping Dublin Core records into the MLR framework.
- Enhance search, discovery and automated filtering of learning objects in LMSs, digital libraries and educational content marketplaces.
- Provide a baseline for building application profiles (see ISO/IEC 19788‑3) tailored to specific communities (education level, technical constraints, rights management).
- Support metadata architects, catalogers and developers in harmonizing metadata for content migration, aggregation and APIs.
Who would use this standard
- Metadata specialists, librarians and catalogers managing educational content
- LMS and repository vendors implementing metadata export/import and search
- Instructional designers and content publishers seeking consistent resource description
- Standards implementers creating application profiles or interoperability layers
