BIBFRAME • Each instance gets a URI • Relationships between works, instances, authorities, places, recorded • Needs to be harmonized with FRBR—Expressions? • FRBR seen as an abstract model • BIBFRAME is a Web implementation
BIBFRAME Timeline • May 2011: Initiative announced • May 2012. Zepheira contracted • Fall 2012. Use cases tested • November 2012. Bibliographic Framework as a Web of Data (high-level model) • October and December 2012. Face-to-face meetings with early experimenters
Early Experimenters • British Library • Deutsche National BibliotekDNB • George Washington University Library • National Library of Medicine • Princeton Library

Linked Data RDA Discovery MDR BIBFRAME
Talk to vendors • Show them MDR • Ask them what their plans are for L.D. • Follow BIBFRAME development • Bibframe.org • bibframe@listserv.loc.gov • Look for RDA records in your discovery tools • Think about search strategies • Ask a cataloger for help! • Link your data • Discographies, bibliographies, thematic catalogs • Digital Humanities projects
