An Ad Hoc virtual meeting on Zoom preceding the next MPEG meeting will take place on Thursday April 23rd immediately following the AHG meeting on genomic information representation, but not later than 17:00 CET (15:00 UTC).  development of the AHG mandates may be scheduled on zoom with the appropriate advanced notice. An Ad Hoc virtual meeting on Zoom preceding the next MPEG meeting will take place on Thursday January 15th immediately following the AHG meeting on genomic information representation.

1. Continue to refine the work plan for Part 28;
2. Continue experiments and tests related to the test data and test methodologies for scene-based media interchange;
3. Continue experiments toward implementing a demonstration of Part 28, i.e., to use the IMS to translate between 3D formats;
4. Study the types of information that should be reported as a result of a translation process, and determine where such information should be stored, e.g.,  in an asset if applicable or in a separate report;
5. Refine the Architecture and implementation aspects of reference software and demonstration for Part 28
6. Continue to study examples of using IMS with other 3D formats, e.g., especially in the creation of the demonstration of Part 28;
7. Write a white paper on SMI, taking into consideration results of the development of a demonstration of Part 28;
8. Continue to solicit industry engagement (e.g., reach out to Metaverse Standards Forum to showcase the demo currently in progress);
9. Refine the requirements of Part 28 especially taking into consideration shortcomings of the current version 1 of the Part 28 and the desire to support additional formats beyond glTF;
