[protege-discussion] Changing many slots to a new metaclass

[Schultz, Ron]

I am unsure whether this helps anyone, but I had a need to reassign hundreds of slots to a new metaclass in order to add synonyms to each slot. While the Protégé user interface allows one to assign a new metaclass to a slot, the effort is time consuming and tedious. I could not find any specific references to how to accomplish this. I needed to do this on only selected classes. The following code snippet, and in particular the last few lines, show the basics. 

		List ownSlots = new ArrayList(frame.getOwnSlots());
		Cls newCls = cls.getKnowledgeBase().getCls("NEW_META_SLOT");
		Iterator i = ownSlots.iterator();

		while (i.hasNext()) {
			Slot ownSlot = (Slot) i.next();
			// Test Code to change the metaclass for a slot
			Cls cls= ownSlot.getDirectType();
			ownSlot.setDirectType(newCls);
			}

If anyone has a more complete example, or knows of another way to accomplish this, please let me know. I was hoping the Protégé Project Wizard plugin would provide this facility but it currently does not.
