scope:

This standard defines the structure of a dictionary of metadata elements that may be used in a range of applications such as production workflow applications, data exchange formats, and archival asset management systems.

The standard normatively defines universal identifiers, metadata element names, definitions, and standardized symbols, as well as other informative fields. These elements may be used as components in structured data models.

I n addition to aiding the interoperability of data between applications, this standard also serves to distinguish similar elements through the unambiguous definitions of these elements and, when necessary, their application or conceptual context. The metadata elements defined by this standard include elements derived from both abstract semantics and application-specific elements.

Applications of individual metadata elements will vary but, when used, metadata shall conform to the definitions and formats in the metadata element dictionary.

Note: The previously published version of this document, SMPTE 335M-2001, had the title "Metadata Dictionary Structure". The title was changed to better describe the role of this document among the set of dictionary structure documents.
