Re: SHACL 1.2 Core & SPARQL

The relevant parts of SHACL core are:

Triple terms:

7.1.3 sh:nodeKind
https://www.w3.org/TR/shacl12-core/#NodeKindConstraintComponent

7.8.5 sh:reifierShape, sh:reificationRequired
https://www.w3.org/TR/shacl12-core/#ReifierShapeConstraintComponent


Text direction:

7.4.6 sh:uniqueLang
https://www.w3.org/TR/shacl12-core/#UniqueLangConstraintComponent

and the datatype can be used to determine if there is a text direction.

7.1.2 sh:datatype
https://www.w3.org/TR/shacl12-core/#DatatypeConstraintComponent
