2.	Support the groups using the file formats (including audio, DASH, CMAF, OMAF, MIAF, V3C systems, Haptics, NBMP et al.)
3.	Study the Technologies under Consideration and Working Draft documents and propose improvements. Study the defect reports and propose corrigendum text.
4.	Study the proposed clarifications on the definition of brands and the use of versions, particularly in the ISO base media file format, and suggest improvements.
5.	Maintain and update the conformance streams, reference software, white papers and one-pagers, and registration authority, as needed. Study whether conformance checking can be (maybe partially) automated, and how the specifications and conformance can be managed as a coordinated workflow. Study the license of the reference software.
6.	Check the specifications for unregistered MIME types and parameters and start registering them. Audit files as needed for the MP4RA.
7.	Explore options for frame rate signalling in ISO base media file format.
8.	Study processes to improve cross-verification of MPEG file format standards and continue the discussion on m60397
9.	(New) Explore alignment of DASH/CMAF/FF terminology, concepts and solutions
