Pillar 4 — Validation (SHACL Core)

pgrdf.validate(data_graph_id BIGINT, shapes_graph_id BIGINT) → JSONB validates the data graph against the shapes graph and returns a W3C sh:ValidationReport-shape JSONB document.

Backed by the shacl 0.3.x crate from the rudof project.

Topics in this pillar

• Mental model.
• Worked example — minCount, datatype, nodeKind constraints.
• SHACL Core components — what's supported.
• Report as data — querying violations with regular SQL.
• 🚀 Forward edge — SHACL-SPARQL — v0.5 custom-constraint surface.

At a glance

SELECT pgrdf.validate(1, 2);
--  → { "conforms": false, "results": [ {...}, {...} ] }
