1 Scope
This part of ISO 14827 defines the format that should be used to document those end-application messages that are to be exchanged between and among central systems. The format is protocol-independent to the extent practical. For example, this one format can be used to
define data exchanges that may apply to DATEX-ASN, CORBA, or other application protocols.
In general, each system can be viewed as consisting of the interfaces as shown in
Figure 1:

This part of ISO 14827 deals only with the communication interface and is at a very high level. Other parts
define how end-application messages can be exchanged using various application layerprotocols.
While this part of ISO 14827 has been designed to meet the unique requirements of a TICS environment, it has been
designed in a generic fashion and thus could be used for other data exchanges as well.
