Map concepts to MPEG-7 DSs and Ds and identify holes in MPEG-7 development

Produce new text defining DS and D for the MPEG-7 Requirements document based on the viewpoint of conceptual modeling

Distinguish existing DSs and Ds according to the new MPEG-7 guidelines

1. Study MPEG-7 profiling using the TVA application as a test case. Specifically:

• What is normative behavior for an MPEG-7 compliant appliance? (e.g., parsing only, or parsing and validation, or parsing and validation and more)
• What needs to be specified in MDS, Systems, and AV Descriptors in order to facilitate interoperability and control of complexity in MPEG-7 devices?
• What is the burden of not having profiles in MPEG-7 on providers, equipment manufacturers, and consumers?

2. To link with the Ad-Hoc group on Integration (Nxxx) for information exchange.

3. Report back results of MPEG-7 based technology submissions to TVA
