The important definition for us is given at
http://www.w3.org/TR/2004/REC-owl-semantics-20040210/rdfs.html#owl_imports_r
df ...

"""
Definition: Let K be a collection of RDF graphs. K is imports closed iff for
every triple in any element of K of the form x owl:imports u . then K
contains a graph that is the result of the RDF processing of the RDF/XML
document, if any, accessible at u into an RDF graph. The imports closure of
a collection of RDF graphs is the smallest import-closed collection of RDF
graphs containing the graphs.
