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)

• Geospatial and Cartographic Resources Ontology (GCRO)

• 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

• Art and Rare Materials (ARM) vocabularies
• Performed Music Ontology (PMO) vocabularies

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

• Stanford Tracer Bullets

Tools built, see also LD4L-Labs

Visualization

• LD4L-Labs' Visualization Tool Prototype for Harvard geospatial and film metadata

Conversion / transformation

• Scala/Kafka/Spark Linked Data Pipeline for converting MARC to BIBFRAME and Reactive pipeline demo

Native linked data creation (Editors)

• LD4L-Labs' The VitroLib Metadata Editor
• Princeton's in-house annotation editor

Repository

• Biblioportal ontology repository (library-specific implementation of Stanford University's BioPortal)

Tool requirements and evaluations

• Registry of Tools used in LD4P
• Requirements for and evaluations of form-based linked data editing tools (CEDAR, Library of Congress BIBFRAME Editor, VitroLib)
• User stories for converting MARC records to BIBFRAME

Use cases for linked data descriptions

• Use cases for art materials
• Use cases for rare materials
