RdfConstraintViolationException class

Exception thrown when an RDF model constraint is violated

This exception indicates that the RDF data violates a specific constraint defined in a data model, schema, or application logic. These are semantic errors where the data is syntactically valid but doesn't comply with higher-level rules.

Examples include:

  • Cardinality violations (e.g., missing a required property)
  • Value range violations (e.g., numeric value out of allowed range)
  • Pattern constraints (e.g., string not matching a required pattern)
  • Graph structure constraints (e.g., missing a required relationship)
