RE: Why Triples? (was Re: What do the ontologists want)

Hmm... but if there are "significant implications" for computational
advantages once one gets to the level of automated reasoners, then this
is an argument that carries much more practical weight than purely
"aesthetic" ones, and _should_ get more air-time. No?

Same with reasoning - how would you go about querying this alongside
e.g. a list of Director, Age Restriction, Country of origin, Duration +
another 4 sets I can't think of... 


Reasoners have been using formats like this since the 1960s. You would
unify the two expressions from left to right. 


I also suspect that there is something happening at a psychological
level in these arguments - it's far easier for a human to relate to
information in a structure like that below - but is this necessarily the
case for machines? 


Yes, there are significant computational advantages. In general, the
more stuff you can incorporate into the unifier, the more efficient the
inference search: you tend to be trading an exponential for a linear
cost, a very good trade.
