The Shapes Constraint Language, or Shacl, provides a vocabulary for defining constraints on R·D·F graphs.
In this sense, it is very useful as a base model for describing how vocabularies should be used, but not very useful for modelling concepts within the vocabularies themselves.
Consequently, most terms from Shacl are not defined here.
