Questions tagged [shacl]

Use this tag on questions concerning the Shapes Constraint Language for RDF: SHACL.

SHACL is a language for validating RDF graphs against a set of conditions. These conditions are also expressed in the form of RDF graphs, called "shapes". Beyond validation, shapes may facilitate user interface building, code generation, and data integration.
