PD ISO/TR 20078‑4 is part four of the multi-series standard that describes the processes of an offering party’s implementation to provide (ISO 20078‑2) access-controlled (ISO 20078‑3) resources (ISO 20078‑1) to accessing parties.
The processes are summarized as: registration of different stakeholder as well as granting, denying and revoking of access to resources. Those processes are held as examples of combining ISO 20078‑1, ISO 20078‑2 and ISO 20078‑3 and can vary depending on the actual implementation of the offering party.
