Method Detail

smush

public void smush(LockableMGraph mGraph,
         Set<Set<NonLiteral>> equivalenceSets,
         boolean addOwlSameAs)

Smushes the resources in mGraph that belong to the same set in equivalenceSets, i.e. it adds all properties to one of the resources in the equivalence set. Optionally owl:sameAs statement are added that point from the IRIs that no longer have properties to the one with properties. If addOwlSameAs is false the IRIs will just disappear from the graph.

Parameters:

mGraph - the graph to smush

equivalenceSets - sets of equivalent resources

addOwlSameAs - whether owl:sameAs statements should be added

getPreferedIri

protected UriRef getPreferedIri(Set<UriRef> uriRefs)

Returns a prefered IRI for the IRIs in a set. Typically and in the default implementation the IRI will be one of the set. Note however that subclass implementations may also return another IRI to be used.

Parameters:

uriRefs -

Returns:
