Karen Coyle's RDA presentation at Code4Lib

Over on the LibLime Developers' Blog, Galen Charlton provides a nice overview of Karen Coyle's keynote presentation on RDA given at the recent Code4Lib conference. I particularly like this section of "Frequently Unanswered Questions":

Of course, a shift to RDF and a more formalized cataloging model would be a drastic change, and raises, as Karen Coyle calls them, some Frequently Unanswered Questions:

• Is FRBR the right conceptual model?
• Is RDF the right format?
• What happens to MARC?
• Who will be in charge?  How will things be decided?

There are other questions — how will library catalogs, data stores, and ILSs have to change if RDA over RDF transpires? How will the existing corpus of MARC data be migrated? How will the systems vendors, open source projects, and cataloging vendors adapt, to say nothing of catalogers, cataloging teachers, and library schools?
