Edge types (stored in corpus.edges.kind) form an open vocabulary — new types are added when data sources provide them. This document lists all known types organized by category.
The properties JSONB column on edges carries type-specific metadata (grounds for partial cassation, commencement date, reservation text, confidence, etc.).
Edge kinds have varying degrees of cross-jurisdiction applicability. Universal kinds (amends, repeals, cites, interprets...) appear in 3+ legal traditions and are documented here. Multi-jurisdiction kinds (cassation_of, preliminary_reference_to...) appear in 2+ jurisdictions. Local kinds (establishes_jurisprudencia, violates...) are specific to one legal system and documented in the emitting plugin. This is a documentation convention, not a runtime constraint — the kind column has no enum. See ADR: edge pipeline architecture (design-decisions/2026-04-22-edge-pipeline-architecture.md).

- All types are directional (A->B) unless marked A<->B.
- The UNIQUE constraint
(source_id, target_id, kind) prevents duplicate edges.
- With nullable
target_id and PostgreSQL's NULL-is-distinct-from-NULL behavior, multiple unresolved references from the same source are allowed.
- Edge properties carry type-specific metadata:
partially_overrules: {grounds: ["moyen_2", "moyen_3"], scope: "partial"}declares_constitutional_with_reservation: {reservation: "conforme sous reserve que..."}commences: {commencement_date: "2024-06-01", extent: "england_and_wales"}suspends: {start: "2024-01-01", end: "2024-12-31"}
- The vocabulary is open — new types added when data sources provide them. No enum constraint in the schema.
