The update has some changes to align the IPTC Photo Metadata Standard more closely which IPTC Video Metadata Hub, which helps with the integration into the C2PA specification as announced earlier this week.
The changes will be presented today (Thursday 10 November) at the IPTC Photo Metadata Conference, alongside sessions on AI and images, C2PA, and accessibility. You can still register for today’s Photo Metadata Conference, for free, at the IPTC Photo Metadata Conference 2022 event page. Video recordings from the event will be posted in the coming weeks.
