Re: SHACL 1.2 Core & SPARQL

Dear RDF & SPARQL Working Group,

A reminder that the Data Shapes WG has produced two specification drafts that we would like you to review: SHACL 1.2 Core and SHACL 1.2 SPARQL. Details below.

To date, we have not had any direct correspondence on this matter from you or via WG members in common.

We are close to finalising these specifications so if you wish to comment, please do so as soon as possible by emailing us or raising GitHub Issues.

Thanks, Nicholas
Nicholas Car & Eliana Papoutsoglou, Data Shapes WG co-chairs
