gbfs-validator-java

Validate GBFS feeds. Intended as Java native alternative to https://github.com/MobilityData/gbfs-validator.

Uses the official json schema to validate files.

Additional validation rules

The interface CustomRuleSchemaPatcher enables adding additional rules dynamically by schema patching:

JSONObject addRule(JSONObject rawSchema, Map<String, JSONObject> feeds);

The raw schema along with a map of the data feeds is passed to this method. The patched schema should be returned.

List of additional rules:

• NoInvalidReferenceToPricingPlansInVehicleTypes
• NoInvalidReferenceToVehicleTypesInStationStatus
• NoMissingVehicleTypesAvailableWhenVehicleTypesExists
• NoMissingVehicleTypeIdInVehicleStatusWhenVehicleTypesExist
• NoMissingCurrentRangeMetersInVehicleStatusForMotorizedVehicles
• NoMissingStoreUriInSystemInformation

Non-schema rules:

Some rules can't be validated with json schema:

Existing rules:

• All version of gbfs require the system_information endpoint.
• In addition, gbfs endpoint is required as of v2.0.

Planned rules:

• Either station_information or station_status is required if the other is present
  • Can this be checked by cross-checking ids between files - using schema patching?
• vehicle_types is required if vehicle types are referenced in other files (already covered?)
• system_pricing_plans is required if pricing plans are referenced in other files
