Jul 1, 2025In July 2025, delivered foundational hazard data modeling for its-client with a focus on consistency, maintainability, and host app reliability. Implemented a HazardCategory-based data model, aligned HazardType with category usage, reorganized hazard-related enums under the roadobjects package, and refined RoadHazard to derive data from DENM. This sets a robust contract for hazard information and simplifies future extensions while improving host app functionality across integrations.

Dec 1, 2024December 2024 highlights: Implemented DSRC/ETSI schema evolution (DSRC 2.0.0), refactor and directory restructuring to align with IS TS 103 301, and updated MAPEM/SPATEM/SREM/SSEM references; introduced improved documentation and versioning for the schema. Added telemetry modularity by making MQTT/OpenTelemetry clients optional and configurable in IoT3Core/IoT3Mobility, with a bootstrap/demo toggle to reflect telemetry state. Completed code quality improvements including removal of easter-egg enum entries and enhanced bootstrap error handling via IllegalArgumentException. Together, these changes improve interoperability, deployment flexibility, reliability, and maintainability while signaling a clear path to 2.0.1 updates in the schema suite.
