Schema Overview

The Indicium schema has one LinkML source of truth: src/indicium/schema/indicium.yaml

From it, four artefacts are generated:

Artefact	Purpose
generated/model.py	Pydantic v2 models for Python consumers
generated/schema.json	JSON Schema for any language
generated/shapes.ttl	SHACL shapes for RDF validation
generated/ontology.ttl	OWL ontology for semantic alignment

Core classes

Claim
 └── evidence: list[Evidence]
      └── of_source: Source

CitationLink   (connects two Claims or a Claim to a Source)

The binding

The one thing Indicium mints is the binding: a claim → typed evidence → a source, provenance-stamped. The claim structure is borrowed from Bucur et al.; the value Indicium standardizes is the typed grounding of claims in evidence.
