In February we wrote about Linked Data basics and resources but only briefly mentioned its application by library vendors. In this post we’ll look deeper into existing and future library applications and services from major library vendors that implement Linked Data.
Before the BIBFRAME model began development, OCLC was already experimenting with Linked Data using the Schema.org model and worked toward expanding its vocabularies to include bibliographic data.
Right now all WorldCat entries include Linked Data. At the bottom of an item record, there is an expandable section headed “Linked Data” which will display the Linked Data schema:
WorldCat displays the Primary Entry and any Related Entries in several standard formats:
- Turtle (text/turtle)
- JSON-LD (application/ld+json)
- RDF/XML (application/rdf+xml)
- N-TRIPLES (text/plain)
- HTML+RDFa (text/html)
BLUEcloud Visibility was announced in a press release on January 7, 2015. SirsiDynix partnered with Zepheira to create this add-in product to work with SirsiDynix’s existing products. They created a pilot program with Douglas County Libraries.
BLUEcloud Visibility transforms MARC21 records to Linked Data. Some features:
- Service to extract your MARC records and transform them into BIBFRAME resources
- Records are enhanced with library location data making them geographically relevant to patrons in your area
- Creates linked data for your library resources, so search engines can index, link them to other resources, and make them discoverable
Currently only library catalog data is included, but the company plans to extend to electronic resources. Currently there is no real-time item availability. Records will be updated twice a month.

Innovative Interfaces is an active sponsor of the Libhub Initiative. In August 2015 they published The ILS and Linked Data: A White Paper to explain why the company was adopting Linked Data and answers some questions about it.
On March 16, 2016, Innovative Interfaces and Zepheira announced a partnership to use Zepheira’s Linked Data technology in Innovative’s new Innovative Linked Data service.
“Innovative Linked Data is available immediately as a subscription service for Polaris, Sierra, Millennium, and Virtua library systems” according to the press release.
In January, Ex Libris announced that the company launched a program to “harness linked data technology in its resource management and discovery solutions” and published the paper Putting Linked Data at the Service of Libraries. The paper details how Ex Libris will enrich products such as their Alma resource management service and Primo discovery service with Linked Data both as a source and a consumer.
Future versions of Alma will ingest BIBFRAME records and enable cataloging librarians to utilize global online authority files such as VIAF for author/creator authority records, Library of Congress Linked Data Subject Headings, and GeoNames geographical place names database.
The next Primo user interface will include Linked Data features to enhance search results. Linked Data will, of course, increase the exposure of the library’s resources to third-party applications and the Web at-large.
Ex Libris is working with its user groups to form Linked Open Data Special Interest Working Groups to help develop and test Linked Data features in the products mentioned. Collaborating libraries include those at Boston College, University of Oklahoma, and University of Amsterdam.
