a) sounds like a good idea    (03)

There's an open source tool for browsing KIF-based theories at 
<http://virtual.cvut.cz/kifb/en/> with download at 
<http://einstein.teknowledge.com:8080/SUMO/SUMO_register.jsp?fileType=.zip&fileName=kifb-1-8.tar.gz>.    (05)

It's free.    (06)

Unless you want a lossy translation, you'll have to use the most expressive 
language, like KIF.  If you try to express a KIF theory in DAML, all the 
rules are lost.    (08)

Having all ontologies expressed in the same language would be a great 
start.  People continually reinvent the same ontologies in different 
languages.  Once that is done, some serious work can start at comparing and 
integrating existing ontologies.  That's the approach we took to create the 
initial versions of SUMO <http://ontology.teknowledge.com>    (010)
