However, TTA FHIR - Notified pull also describes specifications for the generic functions 'authentication' and 'authorization'. These specifications are not compatible with Trust over IP based infrastructures such as Nuts. In addition, TTA FHIR - Notified pull does not describe specifications for the generic function 'addressing'. This means that additional agreements are required for each implementation. The goal of TA-Notified-Pull-on-Nuts is to achieve scalability by expanding Twiin Technical Agreement FHIR Notified Pull with an unambiguous and Trust over IP compliant specfication use of the above generic functions.
