ISO/IEC TR 15938-8:2002 forms an informative part of ISO/IEC 15938 on extraction and use of metadata descriptions for multimedia content.

ISO/IEC TR 15938-8:2002 provides two types of information:

1. informative examples that illustrate the instantiation of description tools in creating descriptions conforming to ISO/IEC 15938, and
2. detailed technical information on extracting descriptions automatically from multimedia content and using them in multimedia applications.

ISO/IEC TR 15938-8:2002 is a companion for ISO/IEC 15938-3 (Visual) and ISO/IEC 15938-5 (Multimedia Description Schemes), which provide normative definitions of the description tools. Effort has been made in this Technical Report to preserve the subclause numbering of ISO/IEC 15938-3 and ISO/IEC 15938-5 to allow easy mapping of the information on extraction and use with those technical specifications.
