What Are Converters? ​
Converters help you translate datasets or messages from one technical or semantic format to another. They are essential for:
- Interoperability – connecting systems using different data standards
- Data exchange – publishing or consuming data in compatible formats
- Modernization – migrating legacy data to current standards
- Automation – integrating conversions into data pipelines or APIs
Converters often include format mapping, schema translation, and metadata transformation features.
Types of Converters ​
| Type | Description | Example |
|---|---|---|
| Schema Converters | Transform data from one schema or structure to another | DATEX II ↔ JSON, XML ↔ RDF |
| Format Converters | Change encoding or syntax (e.g., CSV → JSON) | GTFS → NeTEx converter |
| Metadata Converters | Adapt dataset descriptions to standards like DCAT-AP | DCAT-AP ↔ mobilityDCAT-AP |
| Geospatial Converters | Reproject or transform geographic coordinates or formats | WGS84 ↔ ETRS89 converter |
| Multi-standard Converters | Handle several formats and provide mapping configurations | Multi-schema data gateway |
Common Use Cases ​
Data Publication ​
Convert internal data to DATEX II, NeTEx, or mobilityDCAT-AP formats for publication on a National Access Point (NAP).
Data Integration ​
Transform heterogeneous inputs from different systems into a single harmonized schema.
Migration ​
Convert legacy data (CSV, XML, JSON) into standardized mobility formats for interoperability.
Metadata Alignment ​
Adapt dataset metadata between DCAT-AP and mobilityDCAT-AP profiles for consistent cataloging.
Example Tool ​
DATEX II – JSON Converter
- Converts DATEX II XML files into lightweight JSON
- Preserves core data model semantics
- Useful for APIs and web-based applications
