Note: Before you create and use metaslots (slot metaclasses), you should be confident with the basic Protégé interface and be comfortable designing a project, and creating and modifying classes, slots, forms and instances.
Creating a metaslot is almost identical to creating a metaclass. You simply have to make sure the class is created subordinate to :SLOT. Every metaslot is subordinate to :SLOT. By default, every class subordinate to :SLOT is a metaslot, unless you change it. Frequently, it is desirable to create a metaslot subordinate to :STANDARD-SLOT, so that the slot created using the metaslot will have the various properties defined by :STANDARD-SLOT.
To create a new metaslot:
For example, click the C(reate)
template slots button at the right of the Template Slots pane to create a new
slot. This slot will show up as an instance widget for any slot you create
using the metaslot.
