Implementing Linked Open Data in the Real World Presentations Available

Implementing Linked Open Data in the Real World

Implementing Linked Open Data in the Real World at ALA 2018 on Saturday, June 23 at 10:30am was a program of the Metadata Interest Group. It included the three following presentations on exposing bibliographic and cultural heritage information as Linked Open Data. They introduced participants to Linked Open Data in the real world through both introductory and intermediate level content, including challenges inherent to moving towards a Linked Open Data ecosystem. By exploring beyond Linked Data theory, this program gave participants an in-depth view into the current state of the Linked Open Data movement within cultural heritage communities. The presentations and abstracts are included below.

Linked Data for Production: Pathway to Implementation (LD4P Phase 2)

Presented by Philip Schreur, PhD
Assistant University Librarian for Technical and Access Services
Stanford University Libraries

Abstract: Linked Data for Production: Pathway to Implementation (LD4P Phase 2) builds upon the foundational work of LD4P Phase 1 to begin the implementation of the cataloging community’s shift to linked data for the creation and manipulation of their metadata. A collaborative project among four institutions (Cornell, Harvard, Stanford, and the University of Iowa) and the Program for Cooperative Cataloging (PCC), this phase of LD4P will have seven goals: the creation of a continuously fed pool of linked data expressed in BIBFRAME; development of an expanded cohort of libraries capable of the creation and reuse of linked data through a cloud-based sandbox editing environment; the development of policies, techniques and workflows for the automated enhancement of MARC data with identifiers; the development of policies, techniques, and workflows for the creation and reuse of linked data as libraries’ core metadata; better integration of library metadata and identifiers with the Web through collaboration with Wikidata; the enhancement of a widely-adopted library discovery environment (Blacklight) with linked-data based discovery techniques; and the orchestration of continued community collaboration through the development of an organizational framework called LD4. Taken together, these seven goals will create a firm foundation on which to build libraries transition to linked data.

Linked Data URI workflows at the Digital Virginias DPLA Hub

Presented by Jeremy Bartczak
Metadata Librarian
University of Virginia Library

Abstract: The University of Virginia (UVa.) Library is currently a Digital Public Library of America (DPLA) content hub with plans underway to transition into a regional hub administrator across the states of Virginia and West Virginia. As part of these efforts, UVa. and it’s partners (collectively called the Digital Virginias Hub) will ramp up the number of digital objects harvested by DPLA to around 50,000 by summer 2018. The opportunity to disseminate these unique resources to a broader national audience is even more intriguing when considered against the backdrop of future linked open data initiatives. Thanks to the flexibility of the DPLA Metadata Application Profile, hub metadata can include linked open data URIs as XML attribute values which are harvested and stored by DPLA. This presentation will share some of the strategies employed by the University of Virginia to add URIs to aggregated Qualified Dublin Core XML. In particular the discussion will highlight approaches within a local MODS context and against the backdrop of both new metadata record creation as well as enrichment of remediated legacy collections. The presentation will also cover data modeling challenges for mapping URIs from MODS to a custom Qualified Dublin Core XML hub aggregation schema, and discuss current and future benefits for adding URIs to data harvested by DPLA.

Rare Materials Ontology Extension: from Modeling to Implementation

Presented by Jason Kovari and Francis Lapka

Jason Kovari
Director of Cataloging & Metadata Services
Cornell University

Francis Lapka
Catalog Librarian
Yale Center for British Art

Abstract: Since April 2016, the RBMS Bibliographic Standards Committee (BSC) has collaborated with the Andrew W. Mellon Foundation funded Linked Data for Production project on the Rare Materials Ontology Extension. This work has focused on extending BIBFRAME to facilitate the descriptive needs of rare materials in areas such as physical condition, materials, bindings, exhibitions and much more. Between April 2016 and February 2018, the group focused most of its attention on modeling; this work has benefited from strong collaboration with ArtFrame and the ARLIS’ Cataloging Advisory Committee.
Starting February 2018, our focus is shifting to development of SHACL application profiles and implementing this work in VitroLib, an RDF-based, ontology agnostic cataloging tool being developed as part of the Linked Data for Libraries – Labs project. By ALA Annual, we will implement RareMat within an editor and test the modeling with catalogers. Our work to develop SHACL application profiles and implement in VitroLib will build on work at Cornell building tooling to facilitate cataloging of a Hip Hop LP collection.
In this talk, we will highlight discrete components of the modeling, detail the application profile process and discuss issues and opportunities in our VitroLib implementation. Further, we will discuss the administrative questions regarding long-term maintenance of this BIBFRAME extension and how it fits within BSC’s priorities.
