The most recent meeting of the Ad Hoc Group on Ontology Standards adopted
the upper level ontology resulting from merging content from Cyc, Pangloss,
WordNet, and Penman. This draft reference ontology is now available
for inspection in several formats, as well as on the web from Cycorp
and the KSL Ontolingua
Server. It is currently called hpkb-upper-level on the
Ontolingua Server. Note also, the Ontolingua Server will be
unavailable on 18 November for hardware reconfiguration.
