What is Linked Data?

Wikipedia says…“Linked Data describes a method of publishing

structured data, so that it can be interlinked and become more useful. It builds upon standard web technologies, such as HTTP and

URIs - but rather than using them to serve web pages for human readers, it extends them to share

information in a way that can be read automatically by computers.”

We are used to connecting pieces of information based on their context.

Linked Data makes the relationships explicit (to computers!)

“Just as the traditional document Web can be crawled by following hypertext links, the Web of Data can be crawled by following RDF links. Working on the crawled data, search engines can provide sophisticated query capabilities... Because the query results themselves are structured data, not just links to HTML pages, they can be immediately processed, thus enabling a new class of applications based on the Web of Data.”

Why should librarians care about Linked Data?

“…the Library community’s data carrier, MARC, is ‘based on forty-year-old techniques for data management and is out of step with programming styles of today.’”

“…something new is now needed…”

“The new bibliographic framework project will be focused on…Linked Data principles and mechanisms…”

Web Visibility“When my community searches the web for something we have, we better show up as an option.”

Library of Congress’s Summary1. Libraries have a huge amount of identifiers2. No other community does authorities like we do3. We identify, structure, organize data in different

ways4. With BIBFRAME we can leverage existing Web

standards make library content more visible on the Web

5. Translate MARC skills and practices into a Linked Data context
