- Description:
- The beginning of Section 2 has confused an external reviewer.
From https://lists.w3.org/Archives/Public/public-rdf-shapes/2016May/0000.html
> 2. Shapes
>
> The first paragraph says:
>
> "Shape scopes define the selection criteria"
>
> but then Figure 1 says:
>
> "Scope selects focus nodes"
>
> If a shape is just a graph (or part of a shapes graph), then surely that
> graph cannot actually perform a action, like "selects", as if executed like a
> Java method. Figure 1 also talks about filter shapes that "refine" or
> "eliminate" and constraints that "produce". Talking about graphs as agents
> is deeply confusing.
>
> "Class-based scopes define the scope as the set of all instances of a
> class."
>
> Okay, yes... classes have extensions... after all, RDF Schema 1.1 says that
> "Associated with each class is a set, called the class extension of the
> class, which is the set of the instances of the class" [3]. But what does
> this have to do with defining the set of focus nodes for a shape? The scope
> of a shape is _not_ a specific data graph but the set of all instances of a
> class in the world? - Related Actions Items:
