Credits

The PBCore website and the tools it features were made possible by the generous support of the National Endowment for the Humanities (NEH) and key contributions from many individuals and organizations, including WGBH Media Library and Archives, the Simmons Usability Lab, WGBH Creative, MediaArea, Myers Infosys, Digital Bedrock, and the members of the PBCore Development and Training Project Advisory Board: Rebecca Guenther, Julie Hardesty, Morgan Morel, and Kara Van Malssen.

PBCore would not be possible without the generous support of volunteers from the Association of Moving Image Archivists’ (AMIA) PBCore Advisory Sub-Committee.

This website has been made possible in part by the National Endowment for the Humanities: Exploring the human endeavor.

Elements

Elements defined PBCore is made up of elements, which can be organized into three main groups: Root Elements, Asset Elements, Instantiation Elements. Elements are a way to structure information based on what type of information it is.

To view details about a specific element, click on an element name on the left side of the screen.

- View Elements in XML Hierarchical Order - Expand all subelements

Elements in an XML document must appear in a certain order and hierarchy. The hierarchy for a PBCore 2.1 pbcoreDescriptionDocument is as follows.

Within a pbcoreCollection, the hierarchy remains the same, but the pbcoreDescriptionDocument is contained inside a pbcoreCollection element. If a pbcoreInstantiationDocument is used as the root element, only the Instantiation elements may appear inside the document.

If pbcorePart or instantiationPart are used, all sub-elements must appear in the same order that they would within pbcoreDescriptionDocument (for pbcorePart) or pbcoreInstantiation (for instantiationPart.)

Attributes Defined

Attributes are a way to structure additional types of information that PBCore records can include. Specifically, they are used to further clarify the information you provide as a value to an element.

PBCore Controlled Vocabularies

PBCore Controlled Vocabularies are sets of predefined, community-standardized terms for concepts related to audiovisual and broadcast collections. These terms can be used as drop-down value lists in a database or spreadsheet to ensure consistency in terminology, formatting and spelling, both internally and when exchanging information with outside organizations.

PBCore Controlled Vocabularies include the agreed-upon spelling and formatting for each term, a definition, and a Unique Resource Identifier (or URI). The vocabularies provide only the terms that the community has determined are most widely used and shared, and are not 100% comprehensive. PBCore does not maintain controlled vocabularies for elements that have strong vocabulary options maintained by other authorities. Element pages contain links to relevant external vocabularies, where applicable.

To view the terms and definitions for each vocabulary, click on the name of the controlled vocabulary on the left of the screen.
