Published Subjects

A published subject is any subject for which a subject indicator has been made available for public use and is accessible online via a URI. A published subject indicator is therefore any resource that has been published in order to provide a positive, unambiguous indication of the identity of a subject for the purpose of facilitating topic map interchange and mergeability.
