OK... I agree that it was probably not the best time to discuss updates. :-)

I re-wrote original sample without updates...

http://homepage.mac.com/dmitryv/TopicMaps/TMPath/TologBasedSample1.htm

And ... I realized what I am missing most in Tolog: simple path expressions
for topics.

I really would like to use something like this:

person[X, webPage like  "....", age<20 | age >40],
born-in(X:who,Y:where),city[Y, name like "....."]

person[X, <simple path expressions>] - is a "shortcut", of course, which can
be expressed in real Tolog.
