-<p>Stanbol OntoNet implements the API section for managing OWL and OWL2
ontologies, in order to prepare them for consumption by reasoning services,
refactorers, rule engines and the like. Ontology management in OntoNet is
sparse and not connected: once loaded internally from their remote locations,
ontologies live and are known within the realm they were loaded in. This allows
loose-coupling and (de-)activation of ontologies in order to scale the data
sets for reasoners to process and optimize them for efficiency. The following
concepts have been introduced with OntoNet:</p>

+
+<p>Here are the <code>owl:imports</code> statements for the FOAF and SIOC
ontologies, which are hijacked to "internal" versions managed by Stanbol. Of
course if a domain namespace other than "http://localhost:8080/"; was
configured, you will see that one in each import statement. </p>
+<p>Also note that the import statement for FOAF ends with
<code>http://xmlns.com/foaf/0.1/</code>, which is different from the IRI we
passed to Stanbol <code>http://xmlns.com/foaf/spec/index.rdf</code>. This
happens because in the case of FOAF the <em>physical</em> IRI (which must be
known a priori) differs from its <em>logical</em> IRI (which identifies the
ontology and is discovered only when the ontology is read), and OntoNet tends
to privilege the logical IRI when one is found, i.e. when the ontology is not
anonymous.</p>
+<p>The FOAF and SIOC ontologies are imported by the core space because they
were indicated at <em>creation</em> time.</p>
+<p>Of course it is possible to onbtain a Java object for the ontology using
the Java API. Here is how to export an entire scope to an OWL API object of
type <code>OWLOntology</code>:</p>

<h4 id="ontology_input_sources">Ontology input sources.</h4>
<p>Note that when you add an ontology to a space or session, you pass it an
<code>OntologyInputSource</code> object, or more precisely, an
<code>OntologyInputSource<O,P></code>. This is because there can be
several ways to obtain an ontology, and those most common are supported in
Stanbol. For example, it can be obtained by defererencing a IRI and parsing its
source code (in RDF/XML, Turtle, etc.), or by reading an input stream, or
taking an already stored RDF graph in the Stanbol store; or it could be an
ontology Java object created from scratch. An <strong>Ontology input
source</strong> is an object that incorporates (1) the "method" by which an
ontology should be accessed; (2) the type of Java object it should create to
represent an ontology; (3) where it should store the ontology.</p>
