ISSUE-90: Can the focus node be a literal?
Literal focus nodes
Can the focus node be a literal?
- State:
- CLOSED
- Product:
- SHACL Spec
- Raised by:
- Holger Knublauch
- Opened on:
- 2015-09-21
- Description:
- The spec is vague on that topic, but we need to clarify whether the focus node can also be a literal. My assumption from the SPIN days is that they would only be IRIs and blank nodes, but now I see no real reason for such a restriction. But I have not tried it out yet, so I may be missing some consequences. Does anyone see problems?
A use case would be to allow sh:valueShape to apply to literals too, e.g. to check its own datatype or length, e.g. for qualified constraints.
If we change this, then http://w3c.github.io/data-shapes/shacl/#AllObjectsScope should be generalized. - Related Actions Items:
