A Dataspace Participant Agent performs tasks such as publishing a Catalog or engaging in a Transfer Process. In order to accomplish these tasks, a Participant Agent may use a verifiable presentation generated from a credential obtained from a third-party Credential Issuer. A Dataspace Participant Agent may also use an ID token issued by a third-party Identity Provider. Note that a Dataspace Participant Agent is a logical construct and does not necessarily correspond to a single runtime process.
