Complexity and Expressiveness of ShEx for RDF [PDF]
International Conference on Database Theory, 2015 We study the expressiveness and complexity of Shape Expression Schema (ShEx), a novel schema formalism for RDF currently under development by W3C. A ShEx assigns types to the nodes of an RDF graph and allows to constrain the admissible neighborhoods of ...

Using Shape Expressions (ShEx) to Share RDF Data Models and to Guide Curation with Rigorous Validation [PDF]
Lecture Notes in Computer Science, 2019 We discuss Shape Expressions (ShEx), a concise, formal, modeling and validation language for RDF structures. For instance, a Shape Expression could prescribe that subjects in a given RDF graph that fall into the shape “Paper” are expected to have a ...
