I get the sense from the proposed charter Media Metadata is currently treated sort of monolithically in terms of access to it, its encryptability, and its use in different workflows.  Metadata is quite rich as a part of the media delivery workflow and is getting increasingly important and extensive as media transport and media types evolve.  I propose that it needs more specific focus in the group.

Metadata data and access to it is something that maybe should be considered a distinct type of media content on its own along with having distinct from the transported media authenticated access and encryption considerations that are independent of the media being transported.

This could possibly be part of the “coordinated or cooperative” middle boxes that Lucas has mentioned in his not on the thread “Re: [Moq] "MoQ Architecture" question from Spencer's mail”

Metadata should be more distinctly mentioned in the charter along with perhaps a couple of documents that specifically cover Metadata authentication and encryption and Metadata Use Cases by both end points and middle boxes.
