Java model classes generated from NeTEx (Network Timetable Exchange) XML Schema Definition (XSD) files using JAXB. Maintained by Entur AS.

Overview

This library downloads the NeTEx XSD files from the Entur NeTEx fork and compiles them into JAXB-annotated Java model classes at build time. The generated classes support full marshalling and unmarshalling of NeTEx XML documents, including schema validation against multiple NeTEx versions.

  • NeTEx version: 1.16 (model generation), with legacy validation support back to 1.07
  • JAXB: Jakarta XML Bind 4.x (Jakarta EE 9+)
  • Generated package: org.rutebanken.netex.model
  • GML types package: net.opengis.gml._3

Usage

Release (Maven Central)

    <groupId>org.entur</groupId>
    <artifactId>netex-java-model</artifactId>
    <version>LATEST</version>
</dependency>

See Maven Central for the latest released version.

Snapshot

Snapshots are published to the Sonatype snapshot repository. Add the repository to your pom.xml:

<repositories>
    <repository>
        <id>sonatype-snapshots</id>
        <url>https://central.sonatype.com/repository/maven-snapshots</url>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
    </repository>
</repositories>

Then add the dependency with the snapshot version:

<dependency>
    <groupId>org.entur</groupId>
    <artifactId>netex-java-model</artifactId>
    <version>LATEST-SNAPSHOT</version>
</dependency>

Building from Source

Prerequisites

  • Java 11+
  • Maven 3.x
  • xmlstarlet (apt install xmlstarlet on Debian/Ubuntu, brew install xmlstarlet on macOS)

Build

# Full build: downloads XSD files, generates JAXB classes, compiles, runs tests
mvn clean install

# Run tests only
mvn test

# Package without running tests
mvn package -DskipTests

The XSD files are downloaded from GitHub during the generate-sources phase and placed under src/main/resources/xsd/. The JAXB model is generated into target/generated-sources/xjc/.

Key Technical Details

JAXB customizations (bindings.xjb):

  • Java 8 time type adapters (LocalDateTime, LocalTime, Duration) via threeten-jaxb-core
  • Fluent builder API (withX() methods) via jaxb-fluent-api
  • Property name conflict resolution
  • Package mapping to org.rutebanken.netex.model

Schema validation: NeTExValidator supports validation against NeTEx versions 1.07 through 1.16.

Note on GML types: This library generates classes under net.opengis.gml._3 as part of the NeTEx model.
