Data Dictionary -- Technical Metadata for Digital Still Images

(from the site) This standard is intended to facilitate the development to validate, manage, migrate, and otherwise process master image files of enduring value. Such applications are viewed to be essential components of large-scale digital repositories and digital asset management systems. The data elements document information to enable systems and software to render the images over time. They are also intended to provide managers information to support quality evaluation of digital images over time, as well as provide users with objective information about the source type of the digital image.
