Public Broadcasting Core Metadata Dictionary (PB Core)

Maintained by the Corporation for Public Broadcasting (CPB).

PB Core is an extensive metadata structure supporting the description and exchange of media assets in the public broadcasting community, including both individual clips and full, edited, aired productions. Its elements are divided into sections focusing on intellectual content, intellectual property, instantiations, and extensions. PB Core is maintained under the auspices of the US Corporation for Public Broadcasting, and was influenced heavily by Dublin Core.
