Metadata Record

The place.stream.metadata.configuration record is the core structure that defines how a stream should be presented, used, and distributed. The current lexicon is a starting point for future iterations.

This record is created by users through the Streamplace frontend and contains three main components:

  1. Content Warnings (place.stream.metadata.contentWarnings): Users can select content warnings to indicate to node operators and viewers what types of warnings have been disclosed. The system supports ten predefined warning categories including violence, nudity, flashing lights, language, drug use, death, sexuality, suffering, fantasy violence, and personally identifiable information (PII). These categories are based on the IPTC controlled vocabulary for content warnings. Each warning provides descriptions to help creators properly categorize their content. Streamplace node operators may also configure their nodes to exclude certain types of content.
  2. Content Rights (place.stream.metadata.contentRights): This section captures copyright and attribution information, including the creator’s name, copyright notice, publication year, license type, and credit line. The system supports various pre-defined licensing options from several Creative Commons licenses (CC0, CC-BY, CC-BY-SA, CC-BY-NC, CC-BY-NC-SA, CC-BY-ND, and CC-BY-NC-ND) to “All Rights Reserved”, as well as the option to input custom licensing terms.
  3. Distribution Policy (place.stream.metadata.distributionPolicy): This section currently allows creators to specify a deleteAfter property, which is meant to indicate the time after which the user no longer wants the stream to be made available for playback. It also allows you to optionally restrict syndication of your livestream to a certain set of broadcasters.

When a user creates or updates their metadata configuration through the frontend, the record is published to their Personal Data Server (PDS) with the AT URI pattern at://[did]/place.stream.metadata.configuration/self. When a user goes live, the node extracts this metadata configuration from the local database and uses it to build C2PA manifests for each stream segment. This ensures that every piece of the stream carries the creator’s intentions and requirements for how it should be handled in a tamper-resistant manner.
