Transport information and control systems. Data interfaces between centres for transport information and control systems - Message definition requirements Ingestion-build-79769 this International Standard covers the1 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
