R2RML Mapping for Dspace-CRIS
Works with Dspace-CRIS 5.8

Can be used for RDF-ization of Dspace-CRIS content.

For testing. The mapping provides basic mapping rules and querys for common use cases between the Dspace-CRIS-entities ResearcherPage, Project, OrganizationUnit, and ResearchObject/DigitalObject/2nd Level Entites and their relations to Dspace-entites. Dspace uses the jdyna library to save the informations. For real-world-use, every metadata-field and pointer to other entities (by authority-values) have to be added and adapted singularly. The code here can be used as an template.

• 1. Metadata for Researcherpages
• 2. Relation Item -> Researcherpages using AuthorityValue
• 3. Project/OrganizationUnit
• 4. Relation ResearcherPage -> Project
• 5. DigitalObject/ResearchObject ('bsp')
• 6. Relation ResearcherPage -> DigitalObject ('bsp')
• 7. Relation Item -> DigitalObject ('event')

A Dump of a small own-created dataset (2-3 entites of every entity-type) was successfully created with the tool https://github.com/nkons/r2rml-parser/. R2RML parser also provides a full mapping for the dc-vocabulary for dspace-entities item, collections and communities.

Missing:

• Nested Objects (no)
• Vocabulary for expressing CERIF-entities. Namespace https://www.eurocris.org/ontologies/cerif/1.6/ not available
