This standard defines the syntax of Shape Expression schemas represented in JavaScript Object Notation (JSON), Resource Description Framework (RDF), and plain text. Shape Expressions (ShEx) is a structural schema language for RDF graphs that expresses structural requirements for terms and relationships in a graph. This standard includes formal semantics for validation of RDF knowledge graphs using ShEx. This validation process includes the definition of ShapeMaps to associate nodes in RDF graphs with labeled ShEx. A test suite covers all aspects of syntax and validation.
