Summary

The mediaman working group meeting covered several topics, including the status of documents sent to the ISG, resolution of discuss issues, and a presentation on multiple suffix registration. A significant portion of the meeting was dedicated to a discussion about allowing registration of media types without all suffixes registered, particularly concerning the application/vc+ld+json+jot use case. The working group also touched on community formats, RTP payload formats, and future directions for adopted drafts.

Key Discussion Points

ISG Discuss Issues: Reviewed and discussed five issues raised by the ISG on the top-level media type document. Agreement reached on addressing most issues, with some requiring further work and review.
Multiple Suffixes Draft: Manu presented changes to the suffixes draft, including updates to the registration template, IANA considerations, and the requirement for change controller consent when modifying base subtypes.
Suffix Processing Order: Clarified the processing order of structured suffixes (left to right) and the behavior upon encountering unregistered suffixes or errors.
Media Type Registration Without All Suffixes Registered: Extensive discussion on allowing media type registration when not all suffixes in the type string are registered, particularly for use cases like application/vc+ld+json+jot. Concerns raised about interoperability and the meaning of unregistered suffixes. No clear consensus was reached, indicating a need for further discussion on the mailing list.
Community Formats: Discussed the criteria for community formats, noting the expert's discretion in exceptional circumstances.
RTP Payload Formats: Addressed the issue of managing RTP payload format registrations and the possibility of adding a flag to the media type registry to indicate RTP payload format status.

Decisions and Action Items

ISG Discuss Issues: Address the ISG discuss issues on the top-level document, circulate the updated draft, and request ISG approval.
Multiple Suffixes Draft:
- Address the open issue of whether skipping levels in the registry is acceptable and take the discussion to the mailing list.
- Resolve the application/vc+ld+json+jot use case, potentially involving changes to the media type registration from W3C.
- More review would be nice.
Standard Tree draft: Proceed with working group last call after addressing potential issues raised by the experiment with community format registration. Seek ISG approval for an experimental procedure related to community registrations.
RTP Payload Formats: Jonathan Lennox to raise the issue of RTP Payload Format Registration in ABT Core working group.
