Researchers have introduced a novel method called chain stratification to address the complexities of incorporating default negation into RDF rule languages like N3 and SHACL Rules. Existing approaches often falter due to the limited information within individual triples and the complications introduced by blank nodes in rule heads. This new condition ensures a well-defined semantics for RDF rules with negation and existential rules by analyzing multistep derivations and using integrity constraints to eliminate impossible scenarios. The proposed method guarantees a unique, lean, and justified RDF graph regardless of the rule application order, provided it respects chain stratification, and includes a prototype implementation to demonstrate its practicality.
