Import C2PA content

Support status

The asset registration API automatically read any C2PA metadata attached to an asset, provided the file type is included in the supported C2PA file type list. Due to variations in how different C2PA software providers manage metadata within the C2PA manifest, not all assets with C2PA metadata will offer complete provenance information for Numbers on-chain integrity records. Below is a detailed list of supported C2PA software providers and the specific information that can be utilized in the integrity record Asset Tree.
