"Metadata or data about data are the bits of that stream that complement the essence media and may include such data as timecode, sync, blanking, and color burst information.
Metadata may also include all sorts of descriptive data, such as where the sources originated, how they are composited, where the sources are located on the server or library, the type of special effects incorporated in the edited sequence, how the program is to be distributed, interactive authoring information, frame rates and aspect ratios, how to play this video in various playback devices, digital rights management, etc.
Media asset management (or the IT term DAM for digital asset management) is one of the fastest areas of development in postproduction today. Both displayed products and discussions of media asset management were dominant aspects of the recent NAB convention. In order to provide better communication and understanding, here are a few of the terms commonly used in these discussions and by media asset software manufacturers.
Note that a few of these are far more important to engineers or code-writers and less relevant to those of us who use the equipment or software they develop. But since the terms and acronyms appear before us from time to time, it is good to know what they mean."
