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

What to do now?
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!
