Data Science & Metadata Research

Wikidata is an open knowledge base of structured data that describes any type of entity, including people, organizations, concepts, events, places, and works. Some works described in Wikidata now include a IIIF Presentation Manifest URL. In Wikidata’s default user interface, that URL appears as a link to the Manifest JSON. But Wikidata can be customized to alter the user interface and add new features.

In this presentation we will discuss and demonstrate a Wikidata user script that, for items that include a IIIF Presentation Manifest URL, will embed the ProjectMirador viewer and load the Manifest JSON so that the images referenced in the Manifest can be viewed in the context of other Wikidata statements about the work. 

The discussion will cover how the user script embeds the Mirador3 viewer within a Wikidata item page and how it detects that the viewer should be added. We will also illustrate how one library is including IIIF manifests in Wikidata, with a conversation about learnings from that work, and about how the user script has contributed to the library's understanding of IIIF metadata and Wikidata. The demonstration will show how Wikidata user scripts are created and shared and look at ways in which Wikidata queries can uncover IIIF manifests.

IIIF is an emerging standard for sharing digital structural metadata. OCLC is an active member of the IIIF community and has been working to integrate the standard in is services/products. This talk discusses the experimental IIIF work being done by OCLC Research to help test evolving IIIF standards and help integrate them into production services.

The CONTENTdm Linked Data pilot explores how to convert CONTENTdm data into linked data, how to curate the data in the Wikibase infrastructure, and how to use the data to improve end-user experiences in CONTENTdm. This presentation covers the background research that led to the development of the pilot, the plans for the 3 phases of the pilot, and some early feedback from one of the pilot participants.

OCLC Research is participating in the IIIF Discovery Working Group's on-going effort to develop a "Change Discovery API". The Change Discovery API will provide the information needed to discover and subsequently make use of IIIF resources.

Huddleston and Mixter provide an overview of IIIF Application Programming Interfaces (APIs), and how OCLC is using them across services, as well as our work in supporting standards with other organizations.

This session explores two projects at different points of the prototype-to-production workflow: IIIF (integration of the International Image Interoperability Framework) into a digital discovery environment; and a Linked Data Wikibase prototype (reconciliation tool and editor built to match library metadata workflows) transitioning to production. Temple University presents from the experimenter and practitioner point of view.

Changes to the evolving scholarly record are being driven by evolutions in technology. Tennant explores how interoperability is becoming a key priority with efforts to improve workflows for researchers and reduce admin burden, how research data management is growing in importance, and more.
