Report of the AHG on MPEG-7 Semantic Information Representation

This AHG has been created at the last MPEG meeting in Noordvijkerhout to work in parallel with the CE experiment on the Semantic DS, so as to continue the refinement, both in terms of significance, usage and syntax of the DS’s that have been proposed during the 51st meeting [2] . Following the discussions on the email reflector, and the interaction with the participants to the CE on Semantic DS, syntax changes have been proposed in order to deal with new DDL specifications, incomplete definitions reported in document N3263. In addition, there was a meeting of the AHG on May 30th, 2000 in Geneva. Overall, valuable comments have been provided, some of which represent open issues that will be considered during the 52nd meeting. Below, some listings of the discussions that took place, in reference to the individual mandates of this AHG.
