SEMIC SHACL Validator (Unified Validator)
The SEMIC SHACL Validator is the unified validation service used to assess compliance of RDF graphs, SHACL shapes, and OWL vocabularies with SEMIC semantic specifications, including DCAT-AP, CPSV-AP, MLDCAT-AP, BRegDCAT-AP, and the SEMIC Style Guide.
Purpose
The SEMIC SHACL Validator supports DSSC objectives by enabling automated conformance checking of semantic artefacts, ensuring interoperability, harmonisation of metadata, and improving data quality within European data spaces.
