If you are interested in understanding how metadata is being captured and stored in videos, this is the document to read.
This document discusses additions to the Extensible Metadata Platform (XMP), that provide a model for dealing with digital dynamic media, such as movies that contain many audio and video elements. The document model for dynamic media requires asset management, to allow tracking the history and composition of complex resources. Further, dynamic media objects contain time-related elements, and the metadata for these must be able to model temporal values such as start-time and duration.
This document provides guidance to developers writing applications that read, write, and modify dynamic media documents, so that those applications can maintain the integrity of the composition and editing history and temporal metadata in composed documents, and assign document identifiers correctly and unambiguously.
