How are Multimedia Description Schemes validated by MPEG?
The Multimedia Description Schemes are validated using one of two procedures depending on the type of Description Scheme (DS). First, the specific DSs related to content management, creation, production and usage go through a harmonization process in which the important concepts for description are identified and verified in other multimedia data standards and existing practices. All other remaining DSs go though an experimentation and verification process in which multiple companies implement the DSs in the context of multimedia applications and demonstrate the usefulness and effectiveness of the DSs. In both cases, ultimately, it is the consensus of the Multimedia Description Schemes (MDS) Group that determines the sufficiency of the harmonization, validation, and promotion of the DSs to the MPEG-7 Working Draft (WD).
