Presumably this requires a unique Property instance for each different
link between nodes, for example if I have

John--believes-->SkyIsBlue
John--believes-->MagicPixies

and want to assign 99% confidence to the first one and 1% to the second,
I'd need a 'believes99' property and a 'believes01' property (or reify
both statements and attach the confidence level to those) ?

Or have I misunderstood?

Regards,

David.
