Hi Pellet users,

First of all, many thanks to Rob and Bijan for their answers concerning
how to control debug information.

I have another (unrelated) question. I wonder how n-ary relations (n> 2)
can be represented in OWL.
For example suppose the temperature of an object depends both on its
location and the time of the day as in the foillowing :

temperature(object1,garden,afternoon,20)
temperature(object1,garden,morning,20)
temperature(object1,house,afternoon,18)
....

Of course we could use binary relations such as :

gardenAfternoonTemperature(object1,20)
gardenMorningTemperature(objetc1,10)
....

But it seems quite awkward...

I realize this is not a Pellet-specific question but if any one has any
suggestion I would be grateful,

François
