This part of ISO 8571 defines in an abstract way the externally visible file transfer, access and management service within the OSI Application Layer in terms of:
(a) the primitive actions and events of the service;
(b) the parameter data associated with each primitive action and event;
(c) the relationship between, and the valid sequences of, these actions and events.
The service defined in ISO 8571-3 is that which is provided by the OSI file transfer, access and management protocol ISO 8571-4 in conjunction with the Association Control Service Elements ISO 8649 and with the Presentation service ISO 8822.
ISO 8571-3 does not specify individual implementations or products, nor does it constrain the implementation of entities and interfaces within a computer system. There is, therefore, no conformance to this part of ISO 8571.
