Seven Lessons from LUX,

Yale University’s Linked Data Discovery Platform

Network of interconnected nodes and lines on a gradient background that transitions from a warm golden hue at the bottom to a clear blue at the top. The nodes vary in size and are connected by thin lines, creating a web-like structure. Some nodes appear as filled circles while others are outlined, and the density of the network varies across the image, with some areas more clustered and others more sparse.

Seven Lessons from LUX

Overview

Collections at Yale

Interior of the Yale Center for British Art, featuring minimalist and modern decor. On the left, windows allow natural light to enter and showcase some framed artworks. In the center and to the right, a painting of a seascape hangs on the wall, with dark colors highlighting the dramatic scene of clouds and sky over a beach. The space is spacious and welcoming, with brown sofas inviting visitors to pause and contemplate the artworks. The architecture blends elements of light wood and concrete details, creating an atmosphere of tranquility and reflection.

Room of the Yale University Art Gallery, bathed in natural light filtering through tall windows. Various classical statues and busts on pedestals are observed, creating a calm and contemplative atmosphere. Each piece is accompanied by its own descriptive label, allowing visitors to learn about its history and significance. To the right, a display case contains ancient vessels, highlighted by the light entering through the window and reflecting their intricate details. The exhibition combines elements of classical architecture with a modern and accessible layout, inviting reflection and study of the pieces.

Fossil skull of a Tyrannosaurus rex on display at the Yale Peabody Museum of Natural History. The fossil is well-preserved, showcasing the formidable jaw and sharp teeth of the dinosaur, aspects that allude to its reputation as one of the most powerful predators of the Mesozoic era. The lighting and angle of the photo emphasize the texture and shape of the skull, providing a detailed view that invites contemplation and paleontological study.

Interior of the Beinecke Rare Book & Manuscript Library at Yale University in New Haven, Connecticut. An extensive collection of rare books and manuscripts is stored on glass shelves that reach from floor to ceiling. The warm lighting highlights the spines of the books and creates a serene atmosphere. The architectural structure of the library, with walls of translucent marble, allows natural light to softly filter into the space, protecting the valuable materials from direct light exposure. Known for its unique design and impressive collections, the library is a point of interest for both researchers and visitors interested in the history of books and scholarship.

Four different elements that are part of a collage. In the top left corner, there is a fish fossil found by Benjamin Silliman. In the top right corner, a handwritten letter from Silliman addressed to George Peabody Esq. is displayed with elegant and detailed script. In the bottom left corner, a delicate drawing of the portrait of Harriet Trumbull, niece of the artist John Trumbull, is seen. Finally, in the bottom right corner, a vibrant painting of a battle made by John Trumbull and his teacher, Benjamin West, is presented. Red arrows connect each of these works, illustrating the connections between different pieces in the Yale collections.

What Is LUX?

Integrated access to Yale’s collections
Search and discovery powered by linked open data
Knowledge graph of cultural heritage metadata and resources
Implementation of a shared semantic model (Linked Art)
Focal point for collaboration and innovation across the university

LUX at a Glance

Approximately 41 million entities (as JSON-LD).
Approximately 2.5 billion triples.
Complete library catalog (over 12 million MARC records; includes e-books, but not articles).
Data reconciliation and enrichment from
- Getty: AAT, ULAN, TGN
- Library of Congress: LCSH, LCNAF, Vocabularies
- OCLC: FAST, VIAF
- Wikidata.
Records mapped to Linked Art by contributing units and then enriched through the LUX pipeline.

Goals of LUX

Reveal the cultural heritage collections of Yale University to the world.
Provide a unified gateway to the holdings of Yale’s museums, archives, and libraries.
Enhance user access by providing a novel approach to engaging with both physical and digital collections at Yale.
Uncover relationships among items, prompting users to explore the collections more deeply.

Why Linked Data?

Two fundamental reasons for implementing a linked data approach:

Information management. Organize and share bibliographic information with greater precision and efficiency.
Resource discovery. Facilitate search and retrieval online, leveraging semantics to highlight relationships among resources.

Resource Discovery

The LUX project focused on the second motive, discovery.
Instead of changing our workflows, we focused on proving the value of a linked data approach for our users and our metadata.

Vintage sepia-toned photograph with the ironic staging of the saying Don't put the cart before the horse. A horse stands harnessed behind a small two-wheeled cart, rather than in front of it. The person in the cart, dressed in dark clothing and a cap, appears to be ready to drive, oblivious to the reversed setup. The background features a wide-open field, enhancing the absurdity of the scene with the horse standing still on the grassy path, under a vast sky marked by clouds.

Thesis

The transition from legacy formats such as MARC 21 has been a struggle because we’ve tried to do the hardest parts first.
Change management requires imagination and inspiration.
A discovery system is a concrete reference point that benefits users directly; it can serve as a “north star” for future work.

Metadata Transformations

Conceptual diagram illustrating the relationships between various concepts in the context of metadata for artworks and culture. In the center, the concept of Creation acts as the main node and is connected to Textual Work, Visual Work, Actor, TimeSpan, and Place. Creation is linked to Actor through created by and to TimeSpan through timespan. Actor is broken down into subcategories like Gender/Ethnicity. Visual Work is connected to Digital Content and Physical Object, indicating the different forms a visual work can take. Textual Work is linked to Concept and Place. The diagram uses colors to differentiate types of concepts and arrows to denote semantic relationships, providing a logical structure to understand how data are related in a linked knowledge environment.
