To change the preferences for the OpenId accounts, go to the Options menu -> Edit profile after you signed in. More information on the sign in with OpenId is found here.

Note that it is not necessary to log in if you simply wish to view the public ontologies.

Introduction to the user interface

In building the user interface of WebProtege, we were inspired by the Portal metaphor, in which users can customize the content and layout of the UI. The WebProtege user interface is made up of tabs (e.g., Classes Tab, Property Tab, etc.). Each tab contains several portlets (e.g., the class tree, property values, restriction view, notes, etc.). The user is able to resize and rearrange the portlets in a tab by drag-n-drop.

My WebProtege tab

The first time you access WebProtege, you will see the My WebProtege tab. This tab lists all of the ontologies that are available for viewing and/or editing. Simply click on an ontology name in the Name column to open the ontology.

If you click on the Open in Protege link, a Protege dekstop client will open using the Java Web Start. Both the desktop and the web client are linked to the same Collaborative Protege server. All the edits made in the desktop client will be reflected back right away in the web-client and vice-versa.

Classes tab

After you have opened an ontology, you can view the ontology class hierarchy on the Classes tab. By selecting a class in the Class Tree, you can view the class properties, axioms, notes, etc., in the portlets to the right of the class tree:

If you are logged in, you can also use the Create class and Delete class buttons in the Class Tree to create and delete classes.

Properties tab

The Properties tab displays all of the properties in the currently open ontology:

Individuals tab

The Individuals tab displays all of the individuals in the currently open ontology. Select a class in the Class Tree to see a list of individuals in the Individuals portlet:

Metadata tab

The Metadata tab displays metadata information about the currently open ontology, such as annotations:
