It depends on exactly what you're trying to do and how you've set
up the ontologies.
Ignoring all the details, all you need to do in ont2 is to add the
statement
age RDFS.isSubclassOf employee
where age is set up to be the `age` class and employee is set up to
be the `employee` class. Adding the statement is then one call
to the appropriate Model.add().
However, whether that's the right answer -- "right" as in making
your application work clearly and effectively -- depends on what your
application is trying to do, whether you need to keep ont1 and ont2
separate or bother with ont2 at all, whether `age` is just a named
class or a restriction, etc & co. Which we don't know.
