ISSUE-61: Direction of individual scoping: sh:nodeShape vs. sh:individualScope

Direction of sh:nodeShape

Direction of individual scoping: sh:nodeShape vs. sh:individualScope

State:

CLOSED

Product:

SHACL Spec

Raised by:

Holger Knublauch

Opened on:

2015-05-30

Description:

The SHACL spec currently defines property sh:nodeShape that points from a resource to the shape(s) that it should be validated against. E.g.

ex:MyPerson
sh:nodeShape ex:PersonShape .

Peter's proposal has an intermediate object (of type sh:Constraint) that represents such linkage, e.g.

ex:MyConstraint
sh:individualScope ex:MyPerson ;
sh:shape ex:PersonShape .

(Peter correct me if this is wrong).

We should agree on one mechanism. My belief is that the sh:nodeShape is the more natural and more compact way of representing this, and better aligns with Linked Data principles (how could the system discover a stand-alone constraint at another URI?).

A related question is whether sh:nodeShape would be expected to be in the Shapes Graph (I don't think so).
