To communicate between GTK’s, the technical endpoints must be known. Twiin offers ZORG-AB as a service to find the technical endpoints of other GTK’s. These endpoints are registered in ZORG-AB by the Twiin governance. In this way Twiin makes addressing information public to all GTK’s. However, the use of ZORG-AB is not requirement, and alternate means of obtaining addressing information is permitted. It is not mandatory to use the ZORG-AB interfaces, it is mandatory for the GTK management organisations to inform Twiin about (changes in) the addressing information.
To search for GTK endpoints with ZORG-AB, you can use the Get_Organization and Get_Endpoint transactions.
When additional internal routing is necessary, the Twiin Participant in question is responsible for making relevant routing information available to other participants.
This information may be retrieved by other participants using the applicable Twiin transactions for routing information retrieval, such as:
-
Get HealthcareService (to determine the appropriate internal service or organisational context)
-
Get ActivityDefinition / PlanDefinition (to determine the expected action or workflow step)
These transactions enable the requesting party to obtain sufficient information to correctly populate and direct the notification or workflow Task.
