Folks,
Richard Fikes recently sent out a set of presentations to the DAML
joint-committee list that illustrate axioms that are difficult to represent
in DAML+OIL. It occurred to me that the presentation on temporal ontology
was also relevant to our daml-time group. We've used the Ontolingua
ontologies extensively as a basis for our work on the IEEE SUO.
Here's a list of mappings from the representations in Richard's
presentation to the temporal concepts in the SUMO.
All comments would be welcome. Ian Niles is the main author of SUMO, so
please include him on any comments you may have. You can access all the
SUMO definitions from the SUMO ontology browser at
