Information technology -- Multimedia framework (MPEG-21) -- Part 10: Digital Item Processing
ISO/IEC 21000-10:2006 specifies:
- Digital Item Methods: Tools enabling users to include sequences of instructions for adding predefined functionality to a Digital Item. Digital Item Methods are authored with the Digital Item Method Language, an extension of ECMAScript language (ISO/IEC 16262), which includes a normative set of Digital Item Base Operations. The predefined functionality specified by a Digital Item Method provides a suggested interaction between a User and the Digital Item.
- Digital Item eXtension Operations: Provide for extended functionality not included by the normative set of Digital Item Base Operations to be implemented efficiently in a higher level programming lanuage.
- Linkage with ISO/IEC 21000-2: Tools for integrating Digital Item Methods and Digital Item eXtension Operations with Digital Item Declarations (as specified by ISO/IEC 21000-2).
