This is the start page of the ontology editor. You get here after you have logged in and selected the ontology editor from the set of available services. Clicking on the "Start ontology editor" link takes the user to the table of contents of the ontology library.

We start our ontology editing session by going to the library so that we can load the ontology that we're going to edit. We will make an edit to an ontology called Documents-2 and will then show some of the other features provided by the ontology editor. The Documents-2 ontology contains definitions of terms that might be useful in describing documents. This ontology might be useful, for example, in the definition of the database schema for a bibliographic database.
