The document discusses data validation strategies for cataloguing public services in Brussels, Belgium. It outlines an approach using persistent identifiers (URIs) and standardized information (RDF) with links to other data sources. A key part of the strategy is conformance validation using the Shapes Constraint Language (SHACL) to validate RDF graphs against a set of conditions. Open source and reusable compliance tooling is demonstrated.
