Overview ​

DATEX II Browser is a web-based reference tool for browsing and searching the DATEX II data model. It provides Wikipedia-style ease of use for exploring the complete DATEX II specification, including packages, classes, enumerations, enumeration literals, attributes, and data types.

The tool covers 6,187 structural elements, terms, and definitions (DATEX II v3.6), making it an essential daily reference for anyone working with DATEX II.

Key Features ​

  • Full-text search across all DATEX II model elements
  • Hierarchical browsing through packages, classes, and relationships
  • Multiple version support: Browse different DATEX II model versions (v2.3, v3.4, v3.6)
  • Category filtering: Search by packages, datatypes, enumerations, enumeration literals, classes, or attributes
  • Direct linking: Each element has a unique URL for easy referencing in documentation or discussions
  • Offline capability: Works offline after initial load
  • Mobile-friendly: Accessible on mobile devices
  • Chrome standalone app: Can be installed as a standalone application
  • Static site deployment: Published via GitLab Pages for reliability and performance

Use Cases ​

  1. Quick reference while implementing DATEX II publications
  2. Understanding relationships between DATEX II elements
  3. Looking up definitions of specific terms and concepts
  4. Teaching and learning DATEX II standard
  5. Creating documentation with accurate references to DATEX II elements
  6. Resolving ambiguities in DATEX II specifications

Source Code ​

The tool is open source and available on GitLab:

Development History ​

Originally developed by TamTam Research s.r.o. and presented at DATEX II User Forum in Prague (May 2014). The tool has evolved over the years to support multiple DATEX II versions, with the latest version (v3.6) now hosted at the primary domain browser.datex2.eu.

Presentation: Available on SlideShare (from 2014 User Forum)

Why This Tool Matters ​

DATEX II Browser fills a critical need in the European mobility data ecosystem:

  1. Accessibility: Makes the complex DATEX II standard easily accessible without downloading specifications or opening XSD files
  2. Daily use: Designed for frequent, quick consultations - similar to how developers use Wikipedia or MDN
  3. Proven value: Has been used by the DATEX II community since 2014 (over 10 years)
  4. Version support: Handles multiple DATEX II versions, accommodating different implementation needs
  5. European focus: Directly supports a key European mobility data standard
  6. No installation required: Instant access via web browser
  7. Community resource: Benefits the entire DATEX II implementation community
  8. Open source: MIT licensed, allowing community contributions and transparency

This browser complements other DATEX II tools like:

Developer Note

The datex2json converter is particularly interesting as it demonstrates how to extract and transform DATEX II model data from Enterprise Architect files into a web-friendly format. This approach could be valuable for other standard-specific browsers.

Getting Started ​
