BIBFRAME Data Model Core Classes

WORK: A resource reflecting a conceptual essence of the cataloging item

AUTHORITY: A resource reflecting an authority concept which has a defined relationship to a Work or Instance

INSTANCE: A resource reflecting an individual, material embodiment of a Work

ANNOTATION: A resource that augments another main BIBFRAME class when knowing who asserted the Annotation is vital information

At the advent of 2014, with serious, hands-on work beginning little more than a year ago and a half ago, BIBFRAME—as an Initiative, as a data model, as a vocabulary—is not just walking, it's running.
