Title Railway applications - Rolling stock - Intercommunication between vehicles and train/wayside - Part 1: Data dictionary and rules for functional standardisation
Project Number 14764
Abstract/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.

Normative reference (6)  

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn

(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
