SHACL 1.2 Core & SPARQL

Dear RDF & SPARQL Working Group,

The Data Shapes Working Group (https://www.w3.org/groups/wg/data-shapes/) has produced Editor's Drafts of two specifications - SHACL 1.2 Core & SHACL 1.2 SPARQL - that we invite you to review before we apply to move to Candidate Recommendation in January 2026.

Your WG is listed in our Charter as a dependency and the specific timing motivation for SHACL 1.2 is based on RDF & SPARQL 1.2.


New features in SHACL 1.2 that specifically cater for RDF/SPARQL 1.2 are:

* Constraints on RDF 1.2 Reification
* Use of Reification in Constraint Definitions 

Other new features, including new specifications, are outlined in the SHACL 1.2 Overview document: https://w3c.github.io/data-shapes/shacl12-overview/


Please could you provide feedback by 31 Dec 2025.

Thanks, Nicholas
On behalf of the Data Shapes WG
