Report of the AHG on MPEG-7 Semantic Information Representation

This AHG has been created at the last MPEG meeting in Melbourne to solve the problem of identifying whether semantic description should be separated from the structure description, and to enrich the elements of the Semantic DS. Following the discussions on the email reflector, and on the AHG meeting Dec. 5th, 1999, in Maui, new desirable functionalities for the Semantic DS have been proposed. Further to revise the Semantic DS syntax that would enable such new functionalities to be incorporated, it clearly appears that it should be possible to instantiate only the Semantic DS without having to rely on an often obtained a priori structural decomposition.
