“Add object property” button missing.
I was following the pizza tutorial from U. of Manchester (version 1.3) on creating the pizza tutorial ontology. Couple bumps have been on the way but this missing of “Add object property” seems to bug me a lot.
A search with my dear friend Google returns a useful instruction on how to create the object property:
1). (instead of trying to find the missing “Add object property” button,) Go to the Object Properties tab.
2). In the Object property hierarchy pane on the left-hand side, select “topObjectProperty”.
3). Use the “Add sub property” button to create object properties. <link>
This solution is from Jennifer Vendetti, an administrator of the Stanford protege-owl mailing list (the link above is their archive). This answer to Mila Johns does not mention the difference in interface. I can see that Jennifer is using Windows version of Protege like I do and she has only 3 buttons on the top of the Object property hierarchy tab like I do, as opposing to the tutorial’s Mac’s 5 buttons.

1. I guess I need to attend their workshops for those questions?
2. It looks like Mac is the preferred platform in the world of Protege. I’ve got to find its superiority to go with the crowd. ^^
