Architecture

OpenSTEF is organized into four packages with clear responsibilities: openstef_core provides foundational data structures and utilities, openstef_models implements forecasting models and transforms, openstef_beam handles backtesting, evaluation, and metrics pipelines, and openstef_meta combines models into ensemble forecasts.

Core Package (The openstef_core Package)

Deep dive into openstef_core: the validated dataset hierarchy, shared utilities, and base abstractions that all other packages build upon.

Models Package (The openstef_models Package)

Deep dive into openstef_models: domain-organized transforms, forecasting model implementations, and the model training lifecycle.

BEAM Package (The openstef_beam Package)

Deep dive into openstef_beam: backtesting pipelines, evaluation metrics, analysis tools, and reporting capabilities.

Meta Package (The openstef_meta Package)

Deep dive into openstef_meta: ensemble forecasting, forecast combination strategies, and multi-model orchestration.
