This guideline provides supplementary information to the SMPTE metadata dictionary. The metadata dictionary is a complete list of metadata elements identified by the last 8 octets of the SMPTE universal label (UL). The UL defines a tree structure with a multiplicity of branches (called nodes) and the metadata items are defined as leaves. The dictionary specifies which ULs are nodes and which are leaves. This guideline provides a simplified layout of the metadata dictionary nodes for easy reference. This layout is not a normative reference, but provides sufficient information in a compact form to allow users to both locate metadata items of interest and to provide an easy tool by which new metadata items can be placed within the metadata dictionary.
