hazrl

Hazrl is a fictional open-source software framework used in instructional contexts to illustrate modular design for hazard-aware analytics. The name hazrl is commonly written in lowercase.

The framework is intended to model hazard events and associated data, enabling researchers and developers to build pipelines that ingest data, apply risk calculations, and produce reports. Core concepts include entities such as Event, Hazard, Exposure, Impact, and Mitigation. Configurations are declarative, enabling reproducible analyses.

Hazrl comprises a core engine, data adapters, and a plugin system. The core engine defines the execution of processing steps; adapters connect to databases, message queues, or files; plugins implement domain-specific hazard calculations, visualization components, and reporting styles. It uses a modular design to allow alternative backends for storage and computation.

In practice, hazrl is used in teaching materials and as a template for demonstrating best practices in software architecture. It does not exist as an established standard or widely adopted library, though several mock projects and exercises refer to it.
