Linked data descriptions of library resources
- Natively created descriptions of select items in Cornell's Hip Hop collection (nquads format)
- Encoded dedications (natively created) and BIBFRAME records (converted from MARC) for a representative selection of items in Princeton's Derrida collection
- Library of Congress BIBFRAME Work (over 19 million) and BIBFRAME Instance (around 24 million) descriptions, converted from MARC. Background and instructions: Bulk downloads of Works and Instances; data available at http://id.loc.gov/download/
Ontologies
Art and Rare Materials (ARM) BIBFRAME ontology extensions (includes versioning and change management best practices)
- LD4L Film ontology (and modeling documents)
- Performed Music Ontology (and modeling documents)
- bibliotek-o
- Library of Congress BIBFRAME ontology (while developed prior to LD4P, BIBFRAME was further developed during the course of LD4P, with significant input from LD4P participants) and BIBFRAME “Consultations”: public feedback via the Issues tab in the github repository for the ontology https://github.com/lcnetdev/bibframe-ontology
Controlled vocabularies for use with ontologies
Application profiles
- Art and Rare Materials (ARM) application profiles
- Cornell Hip Hop LPs application profile
- Recommendation for SHACL maintenance and development
Mappings to linked data
- Columbia University Library’s Art Properties metadata to ARM ontology
- MARC 382 field to Performed Music Ontology (PMO)
- Library of Congress' MARC 21 to BIBFRAME 2.0 (see also conversion tool and service)
- MARC BSR to bibliotek-o
- Harvard Geospatial Library FGDC and Harvard Film Archive metadata to BF/bibliotek-o
- BIBFRAME-to-Solr (and SPARQL queries for Solr mapping)
- Tabular MODS-based metadata to BIBFRAME for Stanford sample collection (and Ruby conversion script)
Workflows for producing linked data
Tools built, see also LD4L-Labs
Visualization
