Public constants are those constants which are part of the Upper CYC® Ontology. All public constants should have the marker "PUBLIC" when their Definitional Info is displayed in the KB Browser, and all should be elements of the collection #$PublicConstant in the #$BaseKB.
Public assertions are those assertions which contain only public constants. The "Public Assertions(?)" link in the Term Index for a given constant computes and displays the public assertions which involve that constant. The "?" is used because the public assertions for a constant are not computed ahead of time.
