Trav-SHACL: Efficiently Validating Networks of SHACL Constraints [article]

Mónica Figuera and Philipp D. Rohde and Maria-Esther Vidal
2021 arXiv   pre-print
SHACL models integrity constraints as a network of shapes, where a shape contains the constraints to be fullfiled by the same entities.  ...  Trav-SHACL reorders the shapes in a shape schema for efficient validation and rewrites target and constraint queries for the fast detection of invalid entities.  ...  Rewritten queries are executed against SPARQL endpoints.  ...

A Review of SHACL: From Data Validation to Schema Reasoning for RDF Graphs [article]

Paolo Pareti, George Konstantinidis
2021 arXiv   pre-print
A SHACL document describes a set of constraints on RDF nodes, and a graph is valid with respect to the document if its nodes satisfy these constraints.  ...  We present an introduction and a review of the Shapes Constraint Language (SHACL), the W3C recommendation language for validating RDF data.  ...  shacl Validation by sparql queries The validation of an rdf graph G against a shacl document M can be performed on a shape-by-shape basis.  ...

Magic Shapes for SHACL Validation

Bianca Löhnert, Maria Magdalena Ortiz de la Fuente, Mantas Simkus
The Shapes Constraint Language (SHACL) is the W3C standard for the validation of RDF graphs.  ...  There are already significant efforts to produce optimized engines for SHACL validation, but they focus on fragments of SHACL that restrict the use of recursion and negation.  ...  I learned a lot while working on the master thesis.  ...
