shapes-ISSUE-56 (labra): Inverse triple constraints [SHACL Spec]
http://www.w3.org/2014/data-shapes/track/issues/56
Raised by: Jose Emilio Labra Gayo
On product: SHACL Spec
A common use case is to define constraints on the incoming arcs of a node. In compact syntax, inverse constraints are defined by the "^" operator.
For example:
<IsKnown> {
^foaf:knows @<PersonShape>+
}
defines nodes that receive one or more arcs "foaf:knows" from a node of shape <PersonShape>
The SHACL spec should define the semantics of inverse triple constraints and its interaction with other features of the language.
