European foreword

This document (prEN 15016-4:2022) has been prepared by Technical Committee CEN/TC 256 “Railway

applications”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 15016-4:2006.

In comparison with the previous edition, the following technical modifications have been made:

— The scope has been changed to rolling stock because this is the typical application field.

— The data model has been completely revised to simplify the data exchange by focusing on the

necessary data. Data tables for additional data have been introduced to enable a scalable use of the

data model.

— The purpose of the data model is the structured exchange of item data. The same data model now

also supports the structured exchange of technical document data.

— Rules have been specified to ensure and to check the consistency of the data model.

— A detailed application guide has been incorporated to ensure an easy implementation.

— Because the data exchange is handled by data processing systems an example for layout for a table

of documents and an example for entries in a table of documents is superfluous and has therefore

been deleted.

This document is part of the standard series “Railway applications — Technical documents” which

consists of the following parts:
— EN 15016-1: General principles;
— EN 15016-2: Parts lists;
— EN 15016-3: Handling of modifications of technical documents;
— EN 15016-4: Data exchange.

This document has been prepared under a Standardization Request given to CEN by the European

Commission and the European Free Trade Association.

Introduction

In railway business, the parties require, as part of a contract, bill of material and technical documents. To

support co-operation and effective data exchange of information between customers, suppliers and

partners, it is necessary to have the data exchange precisely defined.

In European directives, the term “Technical Files” is mainly used to summarize types of documents,

drawings, data, reports, etc.
Three main classes of data can be distinguished:
a) Technical data and documents;
b) Maintenance data and documents;
c) Authorization documents, reports, assessments, and safety data.

This document will support the exchange of bill of material and technical documents between two parties.

The aim of this document is to improve cooperation with respect to time, quality, and costs for the whole

railway sector (e.g. railway users, manufacturers, rail system operators, entities in charge of

maintenance).

This document covers exclusively the specification of the data model of the data exchange process

between two parties. Common project management or contractual arrangements aspects like data

content or the handling of change management are not covered.

This document refers to EN, ISO or IEC standards dealing with data fields. In cases where ISO or IEC

standards are not sufficiently precise, this document gives specific details. These additions to EN, ISO and

IEC standards facilitate the exploitation and the administration of the data exchange.

These requirements have been drawn up in order to accommodate:
— the large variety of users;
— ease of transfer of documents;
— any specific series of documentation related to rolling stock.

5.1 General

This Clause describes the organizational and administrative basics of data exchange according to this

standard.
Typically, the source of and target to store the exchanged data are
— PDM (Product Data Management)
— and PLCS (Product Life Cycle Support).

Methods and tooling for retrieving the exchanged data into the receiver repository (like import tool,

required mappings, etc.) are not described in this standard.
5.2 Parties

From the origin of the data (OEM) to the final recipient (final customer) there can be a complex chain of

multiple data shipments, in different levels (tiers) along the value chain. Within this chain there are 4

types of parties (2 dynamic and 2 static):

Static - OEM: The original equipment manufacturer of an item/ the legal owner of a

document. Only one OEM is possible per item/ document.
If this field is empty, this is automatically the Data Supplier.

Static - Final customer: The final recipient of the item/ document (e.g. the operator of the

rolling stock).
It is an optional attribute, that can be added between the submissions
and need to be defined by contract.
The final customer is the same for all items/ documents of one
shipment.
Dynamic - Data Supplier: The party that supplies the shipment
Item independent shipment information
Dynamic – Data Recipient: The party that receives the submission
Item independent shipment information
Figure 1 shows examples of data shipments between four parties.

Table 1 shows the allocation of the shipment parties to the party types for the examples in Figure 1.

Party 1 is the OEM.
Party 4 the final customer.

Party 2 receives data from the OEM (shipment 1), adds the final customer information.

Party 3 receives the data from Party 2 (shipment 2).

The final customer receives data from Party 3 (shipment 4) including data form Party 2 and the OEM.

5.3 Transfer organization
5.3.1 General

This exchange method is a snapshot of the contents of the design. There are no requirements about

history of change management (only the valid version of each piece of information is required).

Before exchanging data, the parties shall accept the scope of the exchange on each project:

— Data supplier (Organization ID);
— Data recipient (Organization ID);
— Configuration Data (Applicability);
— Technical Scope (components, sub-system, vehicles, unit, etc.);
---------------------- Page: 10 ----------------------
oSIST prEN 15016-4:2022
prEN 15016-4:2022 (E)
— Languages of documents;

— Organization for document repository (Directory, media, authorized formats, etc.);

— Planning of submission;
— Identifier for parts (Numbering schemes and unicity rules);
— Common description for items ;
— Data review process ;
— Request for Change Management.
5.3.2 Configuration Management

The data exchanged here will be classed in as “Design Data” with the following parameters:

— Contract Identification;
— Class of Rolling Stock;
— Sub Class of Rolling Stock (if applicable);
— Effectivity (if applicable).
5.3.3 Rules for Data

This exchange data model is versatile. Extra fields may be added in the provided data tables(see 6.3).

Written rules shall be exchanged between parties:

— To agree on the use of data fields with the “importance” values R (recommended) or I (informative),

see 6.2.1;
— to ensure a consistent model on the non-standard requirements.
5.4 Protocol

To track every shipment, besides the data in the Shipment Data Table (see 6.2.2), a handover protocol

(e.g. in pdf format) may be added to it. The format of the exchange protocol can be company specific and

should contain at least the following information if applicable:
— Org ID data Supplier;
— Org ID data Recipient;
— Title of Submission;
— Top Item/ Document in Data Table B/C/D;
— Contract Reference;
— Vehicle reference;
— Date of Snapshot/ data extraction;

— Languages 1, 2, 3;
— Modules included;
— Number of files in Data Table F.
5.5 Shipment review

When the recipient checks and or imports the exchanged data, errors or quality issues can occur. Then a

request for clarification\error correction can be submitted to the data supplier.

Request for clarification (RfC) shall contain:
a) Organization identification code of data recipient;
b) Request Identification (Unique Identifier of data recipient);
c) Contract identification;
d) Shipment date;
e) Document identification;
f) Document Version;
g) Document Date;
h) Shipment error class;
i) Request Description.

If the data supplier accepts the RfC, the two fields (Organization Identification Code and Request

identification) shall be noted in the new data (if needed) and delivered in the relevant fields (depending

on the class of notification).
Shipment error class shall contain:
j) Import errors;
k) Documents analysis and review;
l) Documents Breakdown analysis and review;
m) Items Breakdown analysis and review;
n) Missing items;
o) Missing Documents;
p) Shipment Consistency in table.

6 Data Model
6.1 General
6.1.1 Structure of Data Model

Starting point for the exchange model is the principle that the design of the rolling stock is represented

by a structured list of items down to its most basic (i.e. lowest level) items necessary to maintain, repair

or overhaul the rolling stock during its complete lifetime. This structured list of items is called the

(engineering) Bill Of Material (BOM). In this document the materials are referred to as items (to not mix

them up with the term material used to define the substance/raw material an item is made of).

In the data model this BOM is represented by a so-called Parent-Child relation. This means that each

record of the BOM consists of a Child and its Parent. If a Parent has more than one Child, then there are

as many records with that Parent as there are Children of that Parent. A Parent needs to have at least one

Child. Each Child thereafter can be the Parent for a deeper level in the structure, until the lowest level in

the structure is reached. So, the top of the structure is always a Parent and the lowest level is always a

Child. Table 2 shows an example of a table with a Parent-Child relation. Figure 2 shows this relation in a

graphical representation.

Figure 2 — Examples of Parent – Child relations

Each level in the structure shall be specified. This specification consists of features (meta data) and/or

documents that are linked to the item. Each document shall be linked to the item on the level it describes

e.g. the drawing of the complete assembly of the bogie shall be linked to the item for the complete bogie

and the production drawing for the wheelset axle shall be linked to the item for the bare

European foreword

This document (prEN 15016-4:2022) has been prepared by Technical Committee CEN/TC 256 “Railway

applications”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 15016-4:2006.

In comparison with the previous edition, the following technical modifications have been made:

— The scope has been changed to rolling stock because this is the typical application field.

— The data model has been completely revised to simplify the data exchange by focusing on the

necessary data. Data tables for additional data have been introduced to enable a scalable use of the

data model.

— The purpose of the data model is the structured exchange of item data. The same data model now

also supports the structured exchange of technical document data.

— Rules have been specified to ensure and to check the consistency of the data model.

— A detailed application guide has been incorporated to ensure an easy implementation.

— Because the data exchange is handled by data processing systems an example for layout for a table

of documents and an example for entries in a table of documents is superfluous and has therefore

been deleted.

This document is part of the standard series “Railway applications — Technical documents” which

consists of the following parts:
— EN 15016-1: General principles;
— EN 15016-2: Parts lists;
— EN 15016-3: Handling of modifications of technical documents;
— EN 15016-4: Data exchange.

This document has been prepared under a Standardization Request given to CEN by the European

Commission and the European Free Trade Association.

Introduction

In railway business, the parties require, as part of a contract, bill of material and technical documents. To

support co-operation and effective data exchange of information between customers, suppliers and

partners, it is necessary to have the data exchange precisely defined.

In European directives, the term “Technical Files” is mainly used to summarize types of documents,

drawings, data, reports, etc.
Three main classes of data can be distinguished:
a) Technical data and documents;
b) Maintenance data and documents;
c) Authorization documents, reports, assessments, and safety data.

This document will support the exchange of bill of material and technical documents between two parties.

The aim of this document is to improve cooperation with respect to time, quality, and costs for the whole

railway sector (e.g. railway users, manufacturers, rail system operators, entities in charge of

maintenance).

This document covers exclusively the specification of the data model of the data exchange process

between two parties. Common project management or contractual arrangements aspects like data

content or the handling of change management are not covered.

This document refers to EN, ISO or IEC standards dealing with data fields. In cases where ISO or IEC

standards are not sufficiently precise, this document gives specific details. These additions to EN, ISO and

IEC standards facilitate the exploitation and the administration of the data exchange.

These requirements have been drawn up in order to accommodate:
— the large variety of users;
— ease of transfer of documents;
— any specific series of documentation related to rolling stock.

5 Administration of distributed information
5.1 General

This Clause describes the organizational and administrative basics of data exchange according to this

standard.
Typically, the source of and target to store the exchanged data are
— PDM (Product Data Management)
— and PLCS (Product Life Cycle Support).

Methods and tooling for retrieving the exchanged data into the receiver repository (like import tool,

required mappings, etc.) are not described in this standard.
5.2 Parties

From the origin of the data (OEM) to the final recipient (final customer) there can be a complex chain of

multiple data shipments, in different levels (tiers) along the value chain. Within this chain there are 4

types of parties (2 dynamic and 2 static):

Static - OEM: The original equipment manufacturer of an item/ the legal owner of a

document. Only one OEM is possible per item/ document.
If this field is empty, this is automatically the Data Supplier.

Static - Final customer: The final recipient of the item/ document (e.g. the operator of the

rolling stock).
It is an optional attribute, that can be added between the submissions
and need to be defined by contract.
The final customer is the same for all items/ documents of one
shipment.
Dynamic - Data Supplier: The party that supplies the shipment
Item independent shipment information
Dynamic – Data Recipient: The party that receives the submission
Item independent shipment information
Figure 1 shows examples of data shipments between four parties.

Table 1 shows the allocation of the shipment parties to the party types for the examples in Figure 1.

Party 1 is the OEM.
Party 4 the final customer.

Party 2 receives data from the OEM (shipment 1), adds the final customer information.

Party 3 receives the data from Party 2 (shipment 2).

The final customer receives data from Party 3 (shipment 4) including data form Party 2 and the OEM.

5.3 Transfer organization
5.3.1 General

This exchange method is a snapshot of the contents of the design. There are no requirements about

history of change management (only the valid version of each piece of information is required).

Before exchanging data, the parties shall accept the scope of the exchange on each project:

— Data supplier (Organization ID);
— Data recipient (Organization ID);
— Configuration Data (Applicability);
— Technical Scope (components, sub-system, vehicles, unit, etc.);

5.3.3 Rules for Data

This exchange data model is versatile. Extra fields may be added in the provided data tables(see 6.3).

Written rules shall be exchanged between parties:

— To agree on the use of data fields with the “importance” values R (recommended) or I (informative),

see 6.2.1;
— to ensure a consistent model on the non-standard requirements.
5.4 Protocol

To track every shipment, besides the data in the Shipment Data Table (see 6.2.2), a handover protocol

(e.g. in pdf format) may be added to it. The format of the exchange protocol can be company specific and

should contain at least the following information if applicable:
— Org ID data Supplier;
— Org ID data Recipient;
— Title of Submission;
— Top Item/ Document in Data Table B/C/D;
— Contract Reference;
— Vehicle reference;
— Date of Snapshot/ data extraction;

— Languages 1, 2, 3;
— Modules included;
— Number of files in Data Table F.
5.5 Shipment review

When the recipient checks and or imports the exchanged data, errors or quality issues can occur. Then a

request for clarification\error correction can be submitted to the data supplier.

Request for clarification (RfC) shall contain:
a) Organization identification code of data recipient;
b) Request Identification (Unique Identifier of data recipient);
c) Contract identification;
d) Shipment date;
e) Document identification;
f) Document Version;
g) Document Date;
h) Shipment error class;
i) Request Description.

If the data supplier accepts the RfC, the two fields (Organization Identification Code and Request

identification) shall be noted in the new data (if needed) and delivered in the relevant fields (depending

on the class of notification).
Shipment error class shall contain:
j) Import errors;
k) Documents analysis and review;
l) Documents Breakdown analysis and review;
m) Items Breakdown analysis and review;
n) Missing items;
o) Missing Documents;
p) Shipment Consistency in table.

6 Data Model
6.1 General
6.1.1 Structure of Data Model

Starting point for the exchange model is the principle that the design of the rolling stock is represented

by a structured list of items down to its most basic (i.e. lowest level) items necessary to maintain, repair

or overhaul the rolling stock during its complete lifetime. This structured list of items is called the

(engineering) Bill Of Material (BOM). In this document the materials are referred to as items (to not mix

them up with the term material used to define the substance/raw material an item is made of).

In the data model this BOM is represented by a so-called Parent-Child relation. This means that each

record of the BOM consists of a Child and its Parent. If a Parent has more than one Child, then there are

as many records with that Parent as there are Children of that Parent. A Parent needs to have at least one

Child. Each Child thereafter can be the Parent for a deeper level in the structure, until the lowest level in

the structure is reached. So, the top of the structure is always a Parent and the lowest level is always a

Child. Table 2 shows an example of a table with a Parent-Child relation. Figure 2 shows this relation in a

graphical representation.

Figure 2 — Examples of Parent – Child relations

Each level in the structure shall be specified. This specification consists of features (meta data) and/or

documents that are linked to the item. Each document shall be linked to the item on the level it describes

e.g. the drawing of the complete assembly of the bogie shall be linked to the item for the complete bogie

and the production drawing for the wheelset axle shall be linked to the item for the bare axle
