Preliminary Agenda for LD4 Workshop

Experiences and priorities of major communities implementing linked data in libraries: latest activities of the European BIBFRAME community, including work with ILS vendors; role of the Program for Cooperative Cataloging (PCC) in linked data implementation in North America; and report from the RDA (Resource Description and Access) community.

A grounded overview of methods for interacting with Wikidata, especially via the SPARQL endpoint and the Mediawiki action API.

This project is creating linked open data for archival and special collection materials related to Indigenous communities in North America, using Wikidata to incorporate traditional knowledge structures as valid conceptual frameworks with a focus on provisions to respect and defend the agency and authority of individuals, families, and communities to exercise their right to not participate, or have their information used in linked data initiatives.

This exploration of the application of Wikidata into linked data environments in research libraries focuses in particular on Wikidata's place as a source for identifiers. Wikidata was chosen because of its easy-to-use interface and its ability to act as a linking hub to other linked data stores.

This case study of the migration of Northwestern University Libraries’ digital image repository to Hyrax/Fedora 4 will cover reconciliation with OpenRefine; mapping among Dublin Core, BibFrame, VRACore3, and schema.org; the use of multiple controlled vocabularies; extending the Hyrax metadata editor; and integration with Primo discovery environment.

The Ontario Council of University Libraries (OCUL) Scholars Portal (SP) provides shared technology infrastructure and shared collections for all 21 university libraries in the province. This case study describes SP’s project to model journal entitlement and collection metadata as linked data to build links among SP collections and to interact with external sources for enhanced discovery. Topics addressed include modeling decisions and use of existing ontologies; experience with the functionality of the MarkLogic Semantics platform; challenges of integrating data from various sources; and plans for integration with local library systems.

This case study describes implementation of a Fedora-based digital asset management system that supports discovery across multiple metadata schemas describing library resources as varied as wine labels, historical photos, and digitized books.

The Program for Cooperative Cataloging (PCC) develops and maintains the BIBCO Standard Record (BSR) and the CONSER Standard Record (CSR) Metadata Application Profiles, which guide catalogers in creating authenticated bibliographic records according to PCC and RDA guidelines. Mapping these application profiles to BIBFRAME raises questions about ontology modeling and about mapping maintenance.

SHARE-VDE (www.share-vde.org) is a research and development initiative driven specifically by the library community to facilitate the implementation of BIBFRAME in libraries. This presentation describes the project components including: conversion of over 100 million bibliographic and authority records from 12 North American institutions to BIBFRAME 2.0; reconciliation of entities within the set of converted data, creating a knowledge base of clusters; enrichment of these reconciled clusters with URIs from external sources; and the publication, supply, and management of authority and bibliographical data in RDF. Technical hurdles will be described, along with the solutions adopted, results, feedback, and evidence received from the international library community.

UC-Davis is one of 3 institutions piloting a new suite of linked data services using out-of-the-box services from WikiBase and entities available from FAST, VIAF, and Wikidata to 1) reconcile names for people, organizations, concepts, places, and events against an index based on entities, returning language-tagged headings and persistent identifiers; and 2) create, share and edit entity descriptions while also allowing for the contribution of additional contextual relationships between entities, beyond those that can be found by mining structured data in bibliographic and authority data via an Editor. The partnership aims to build new tools and best practices for designing linked data environments for production-level library workflows.

This presentation describes the architecture of a robust set of authority services that serve linked data on demand, with response times sufficient for integration into an end-user application. The presentation will demonstrate on-the-fly linkage between BibLeo, a sandbox catalog prototype, and DBpedia, both indirectly via VIAF authority data for persons, and directly for works, merging related images and data from DBpedia with local catalog data.

In a linked data model, libraries can describe manifestations by pointing to existing work descriptions, without having to duplicate those descriptions, but how will this model accommodate work metadata that will be expanded and improved after initial creation? This presentation will describe a model for caching entities, allowing dynamic updating.

Through the example of the World-Historical Gazetteer project, this presentation will discuss the challenge of creating a sustainable ecosystem for linked data resources. Also addressed will be potential areas of collaboration between the historical gazetteer community and libraries.
