Initiated by the Library of Congress, BIBFRAME provides a foundation for the future of bibliographic description, both on the web, and in the broader networked world that is grounded in Linked Data techniques. A major focus of the initiative is to determine a transition path for the MARC 21 formats while preserving a robust data exchange that has supported resource sharing and cataloging cost savings in recent decades.

This repository contains the BIBFRAME 2.0 Vocabulary bibframe.rdf and Library of Congress Bibframe local extensions bflc.rdf and is intended for tracking issues and changes to the vocabulary.
