Validation Strategy

Validation is catalog-driven and deterministic. It prioritizes correctness and reproducibility over heuristic discovery.

Pipeline Overview

1. Syntax validation for JSON-LD and Turtle
2. Coherence checks between SHACL target classes and OWL classes
3. SHACL conformance checks for JSON-LD instances
4. Regression checks for invalid test cases

Catalog-Based Discovery

• Required OWL and SHACL files are resolved via XML catalogs.
• Base ontologies from imports/ are filtered by actual usage in data.
• Fixtures are resolved via tests/catalog-v001.xml.

Inference

The validation pipeline applies RDFS inference to ensure shape targeting works across subclass hierarchies.
