The document discusses RightsML, a standard for expressing rights metadata for digital content. RightsML is based on ODRL, an open standard for specifying rights using machine-readable permissions. It allows publishers to specify the permissions and restrictions for use and reuse of content. The Rights Expression Working Group is working to refine and promote RightsML and ODRL, including developing examples, expressing ODRL in JSON to support embedding in media files, and engaging with organizations to help drive adoption.
