The initial check-in files of SUMO (Dec 4 2000) stated:
;; Note that among the primitive predicates are several (e.g.,
;; "exists-at") that are borrowed from other ontologies -- moreover,
;; those predicates may be *defined* in those ontologies. Eventually,
;; of course, it will be important to have mechanisms for making such
;; connections explicitly (via, e.g., something like Ontolingua
;; packages).
There are some Ontolingua papers online at:

For now I'd just add traceability to the list of 'ility-s' below.
