First Public Working Draft: SHACL 1.2 SPARQL Extensions

SHACL 1.2 SPARQL Extensions

https://www.w3.org/TR/2025/WD-shacl12-sparql-20250318/

Published by
 Data Shapes Working Group

Abstract

This document defines SPARQL-related extensions of the SHACL Shapes Constraint Language. SHACL is a language for validating RDF graphs against a set of conditions. These conditions are provided as shapes and other constructs expressed in the form of an RDF graph. While the Core part of SHACL defines the basic syntax of shapes and the most common constraint components supported by SHACL, the SPARQL-related extensions cover features that extend the expressiveness of Core by means of SPARQL. In particular, this document defines how constraints and constraint components can be defined using SPARQL. 

TODO: More will be added on Node Expressions/targets once that part is ready. Other features from SHACL-AF such as user-defined functions may get added.
