From the Zepheira Website
The National Library of Medicine (NLM) today published a synopsis of their work with Zepheira, George Washington University (GWU), and University of California, Davis (UCD) in development of the BF Lite vocabulary, as hosted by Zepheira.
The approach was unique, as NLM is creating new cataloging data directly in BF rather than converting legacy bibliographic data.
