OCLC’s role in advancing library linked data

There are times when a single organization’s decision to embrace a particular technology will have an outsized influence on everyone else in that sector. For example, with the release of “Toy Story” in 1995—the first feature-length film entirely created with CGI—Pixar set a new standard for animated movies. While CGI had been used before, the success of Pixar’s approach encouraged other studios to adopt the technology more quickly and fully.

We are at a moment like this today. The shifting of operational workflows to incorporate linked data will transform how libraries create, manage, and improve WorldCat, the largest source of library metadata in the world. OCLC’s strategy to champion this change, along with the support of its thousands of members, represents a significant event for the library profession worldwide.

How linked data can help libraries make more of an impact online

In a recent post, I introduced the topic of linked data for libraries and OCLC’s plans for moving forward. Today, let’s dig into the details on how linked data amplifies the knowledge in library collections and the tools we can use to make it happen.

This shift toward linked data isn’t just a technology upgrade, but a long-term strategy for enhancing the findability and accessibility of the important materials that libraries curate and manage. It’s a technical challenge, yes. But I also believe it’s a chance to better promote our values.

An introduction to library linked data

We recently announced a comprehensive strategy to bring linked data into mainstream library cataloging workflows. It’s a long-term approach, recognizing that most libraries will move to linked data slowly and incrementally—and we’re committed to providing tools and resources to support the transition for everyone.

Working closely with libraries around the world, we know that staff at some libraries are already educating themselves on the topic, piloting linked data services, and taking part in ongoing research. But we also know that many others have a lot of questions. In addition to technical issues, librarians are also wondering how linked data will impact and affect the work they are currently doing. To help, OCLC is rolling out linked data infrastructure and services that meet libraries where they are today and provide meaningful improvement to challenges facing libraries.

Can you imagine a world without WorldCat?

WorldCat is a legend—a remarkable achievement in global collaboration. What began as a way for a handful of academic libraries in Ohio to distribute the cost of cataloging has turned into a critical, core asset for libraries around the world.

WorldCat is not just a place for individual libraries to write and store MARC records. Collaboration among our metadata experts, libraries, and many partners has evolved WorldCat to the point where it is a hub for an astonishing volume of library activities every day. The one thing that hasn’t changed is our global, community commitment to ensuring that high-quality, library-centric data is available now and in the future.

How your library will benefit from linked data

In January 2020, OCLC announced that the Andrew W. Mellon Foundation had awarded us a grant to build a shared entity management structure that supports libraries as we move toward new ways to create and share information about their collections. These new methods—commonly referred to as “linked data”—represent changes to both underlying library data and the type of activities that library workers perform.

Even more importantly, they also signal a shift in how the library community can work together to build on each other’s work. I believe that no matter what type of library you are associated with, you and your users will benefit from this project.

Putting linked data to work

linked-data-developer

OCLC has been working a lot with linked data in recent years, and we have described some of that work at a very high level in this space before. That work continues, but now we are also adding an educational component to that work. Since we want our member libraries to be able to take advantage of all of the linked data that is becoming available—both from us and from the world at large—we want to help library software developers understand the tools and strategies for consuming linked data.

Turning bibliographic metadata into actionable knowledge

metadata-knowledge

OCLC has been publishing bibliographic linked data since 2012. Since then we have published three major datasets as linked open data: WorldCat.org, WorldCat Works and OCLC Persons.

As we continue to work on creating and publishing linked data, a key goal is to demonstrate how this technology fits into library workflows and how it can add value for both librarians and users.

As part of this process, OCLC Research has used the recent work of Google Research as inspiration for the development of a Knowledge Vault pipeline. The focus of our effort is to develop a pipeline process that allows for the harvesting, extraction, normalization, scoring/weighting and synthesizing of knowledge from Authority files, bibliographic records and eventually resources from across the Web such as WikiData or user-contributed feedback.

Getting started with linked data

2016-02-04-Roy-linked-data

“Linked data” is a popular topic at library conferences these days, with overflow crowds wondering what it might mean for their institutions and their personal professional development. Why? Because linked data can be easily understood by computers, resulting in opportunities for improved library workflows, enhanced user experiences, and discovery of library collections through a variety of popular sites and Web services, including Google, Wikipedia and social networks.

Before briefly explaining the nuts and bolts of linked data, it is important to point out that for most libraries and librarians the sea change from records full of text strings to fully linked data elements will largely occur under your radar.
