[This is a starter for metadata recommendations in Fedora 5.x.]
Managing metadata in Fedora 5.x means considering how best to make use of RDF and Linked Data. Fedora 5.x enables RDF properties to be defined for objects it stores or references. This includes all types of metadata, such as technical, rights, provenance, and descriptive.
Fedora 5.x uses a set of internal properties (see http://fedora.info/definitions/v4/repository) and supplies the following ontologies by default:
fedora: http://fedora.info/definitions/v4/repository# rdfs: http://www.w3.org/2000/01/rdf-schema# webac: http://fedora.info/definitions/v4/webac# [list of default namespaces needed]
It is possible to include and use any ontology that exists, although it is recommended to use ontologies that are shown to be currently active and well-maintained for longevity purposes.
The Samvera Community has developed metadata recommendations, including mapping recommendations for objects currently defining metadata using XML.
Samvera Community Metadata Recommendations:
- Technical Metadata Application Profile
- Rights Metadata Recommendation
- Referring to segments of a file - Recommendation
Additional Recommendations / Works in progress:
- Decision Tree for New Predicates/Vocabularies
- Samvera MODS to RDF Mapping Recommendations (work in progress)
- Islandora MODS to RDF Mapping Recommendations (work in progress)
It is possible to use metadata in XML format (or JSON or other file formats) alongside stored digital objects in Fedora 5.x but editing, management, and integration with access systems such as Hyrax will require that metadata is added and maintained as RDF properties. See Common metadata design patterns for examples of ways to best take advantage of Fedora's capabilities.
