Architecture

Overview

The RE indicators calculation service is a dedicated, containerized HTTP service implemented in Rust.

Its responsibility is narrow:

• accept RE indicators computation requests
• resolve the selected RE indicators specification version
• validate against SHACL artifacts
• compute and return structured scoring results

Core Service Boundary

The service is intentionally not model-generic.

• fixed model family: re-indicators-specification
• variable model dimension: version tag only
• validation basis: published SHACL artifacts

Internal Layers

The implementation should evolve around these layers:

• HTTP API layer: request parsing, response formatting, status codes
• artifact resolution layer: load published artifacts for a selected version
• validation layer: execute SHACL validation against the selected artifact set
• computation layer: derive parameter and total scores from the model-driven logic
• mapping layer: produce a structured response suitable for downstream digital passport use

Deployment Shape

The intended deployment unit is a single service container.

No CLI or SDK is a primary deliverable for this repository.
