This page displays the Credential Transparency Description Language schema in an RDF-centric format. Below you will find every class, property, concept scheme, and concept for this schema, each with a thorough description and connections to other terms.

The following tables use a common set of attributes to describe each Term. Not all terms will have all attributes.
