Ajax GUI For OWL (Web Ontology Language)

Creating an Ajax-based GUI that will allow the creation of OWL classes or OWL Individuals within an ontology, based on the properties and subclasses declared in the ontology (no new properties to be declared).? Create a target class to which we can drag & drop ontology properties and OWL constructs to give that class the characteristics the user wants. For example, we have an ontology that has the classes #animal, #plant and the property #eats. The user should be able to construct a new class that is a subclass of #animal and has a restriction on property #eats, taking values only of type #plants. So in essense, the user has constructed a new class describing herbivore animals.? That class should then be exported in text form in a file. That's it.
