You'd do this in exactly the same way as you're describing alice
as a person
. Like this:
con.add(person, RDF.TYPE, RDFS.CLASS);
Similarly for the other things you want to add (assuming you've created a URI for bookTitle):
con.add(bookTitle, RDF.TYPE, RDF.PROPERTY);
con.add(bookTitle, RDFS.DOMAIN, book);
etc.
I should point out that although it is of course possible to create your schema or ontology in this fashion, it might be easier to instead create a file containing your ontology (e.g. in Turtle or N-Triples syntax), and then simply upload that file to your Sesame repository.
