Class ModelExpansion

  • public class ModelExpansion
extends java.lang.Object
    The ModelExpansion code expands a model M against a schema S, returning a new model which contains
    • the statements of M
    • any statements (A rdfs:subClassOf B) from S where neither A nor B is a bnode.
    • statements (A rdf:type T) if M contains (A P any) and S contains (P rdfs:domain T).
    • statements (A rdf:type T) if M contains (any P A) and S contains (P rdfs:range T).
    • statements (A rdf:type T) if (A rdf:type U) and (U rdfs:subClassOf T).
    This is sufficient to allow the subjects in M which have properties from S to have enough type information for AssemblerGroup dispatch.

        public static Model withSchema​(Model model,
                               Model schema)
        Answer a new model which is the aggregation of
        • the statements of model
        • the non-bnode subclass statements of schema
        • the subclass closure of those statements
        • the rdf:type statements implied by the rdfs:domain statements of schema and the model statements using that statements property
        • similarly for rdfs:range
        • the rdf:type statements implied by the subclass closure

      • addSubClassClosure

        public static void addSubClassClosure​(Model m)
        Do (limited) subclass closure on m.

        Those classes in m that appear in subClassOf statements are given as explicit superclasses all their indirect superclasses.
