Re: [PNG] Meeting topics - Oct 27th, 2025

@Chris Blume (ProgramMax)<mailto:programmax@gmail.com> - happy to chat about C2PA (and PNG) at the meeting on Monday, but curious who is raising the issues and what the overall concern is - either in general, or for PNG or both.

Hello everyone,

This coming Monday is a PNG WG meeting. I think we should discuss:

  *   C2PA apparently has some problems. The chunk can be removed, sure. And a new chunk could be created to claim ownership. This much is expected. You would need to look at the dates on the claims, right? But maybe there are problems beyond that?
  *   TPAC 2025 is coming up shortly. We have a time slot to meet and also give other groups more vision into our work. I expect we'll give a summary of our work so far and field questions. Let's discuss what we should have prepared for TPAC.

See you Monday!
