Railway applications - Rolling stock - Intercommunication between vehicles and train/wayside - Part 1: Data dictionary and rules for functional standardisation

Scope

This Technical Report will define - requirements for the methods to be used for functional standardisation, in the standards to be prepared for data exchange involving railway vehicles, in two contexts 1) inter-consists communication, within a train formation, 2) communication with ground based installations. - the Reference Architecture defining the essential functional interfaces, - the concept of a central Data Dictionary/repository to be applied to freight and passenger traffic functions. In this context, data are to be limited to basic information elements, which are necessary to define standard messages required for interoperability, and displayed on the interfaces of the communicating entities. Entering Data Dictionary will provide full definition of a data element, along with its essential attributes at conceptual level. The purpose, in the perspective of the standards to be prepared, is to document the data element pertinent to the functional area and essential for interoperability, to allow the reuse of data element among functional area systems, and facilitate data interchange among the systems. NOTE Data Dictionary shall be designed to provide a structural framework that enables continued growth and enhancement of the scope of defined data. Rationale for this requirement is that it is difficult, when defining the scope of a proposed system to fully define the application domain and all included interoperability related data. In addition over time, functional requirements will expand.
