The Dynamic Attribute Token (DAT) Payload is the JSON Element of any DAT containing the claims of the token bearer. This payload itself is a JSON-LD encoded RDF class with a defined set of attributes. These attributes are either defined by RFC 7519 or by the IDS Information Model. As a direct consequence of regarding the DAT Payload as JSON-LD, *all* DAT Payloads must have exactly one “@context” attribute with the IDS context URI as its value and a “@type” with ids:DatPayload as its value.
