Within the network, all Herkenningsmakelaars, Authenticatiediensten and Machtigingenregisters should exchange each others metadata, so the systems can verify the origin of a request and subsequently process it.
The beheerorganisatie has a process in place to aggregate metadata and publish one file which contains all relevant metadata. For the test environment, this also contains the metadata for all simulated entities, including the simulated Dienstverlener.
Refer to Proces netwerkmetadata for the process of metadata aggregation.
