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.”

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.”

“…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 Summary
1. Libraries have a huge amount of identifiers
2. No other community does authorities like we do
3. We identify, structure, organize data in different ways
4. 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
