Dev:Splitting and merging railML files

Introduction

This is a guide on splitting and merging railML files.

Problem statement

Users have a big file with railway network and lines in it. Reading software may not support importing this big file. Users want to extract lines from the network to separate files and then (after import) to bring lines back into one network. Splitting and merging of lines may be done by different parties and different tools.

Railway sector actors should be able to prepare their data for splitting and integration in a unified standardized way i.e. split files into (lines) parts intended for integration in an automated way, define explicit points for connection.

General concept

Connector <netElement> is a redundant <netElement> marking a “border” of a file. It exists in both files after splitting.
