Changing the Metaslot of a Slot

Note: Before you create and use metaslots, you should be confident with the basic Protégé interface and be comfortable designing a project, and creating and modifying classes, slots, forms and instances.

If you have multiple metaslots in your project, then for any existing slot, you can change the metaslot you use for that slot. This gives the slot and the Slot Form the attributes defined by the new metaslot. Subslots that you create subordinate to the slot will also use the new metaslot. However, existing subslots will continue to use their previously assigned metaslot unless you specifically change it. 

To change the slot metaclass (metaslot) of an existing slot:

  1. In the Slots Tab, click on the slot that you want to change. 
  2. Click the right mouse button and select Change slot metaclass....
  3. A dialog box displays the slot metaclasses. Note that if the class currently uses a non-standard class, you can revert to :STANDARD-SLOT.
  4. Select the metaslot that has the properties that you want and click OK. 
    The highlighted slot will now have the Slot Form and properties determined by the selected metaslot.
