Class ModelExpansion

java.lang.Object

org.apache.jena.assembler.ModelExpansion

public class ModelExpansion
extends 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.

withSchema

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.
