I like these categorisations.  However I think Trust should read
"Trust and Reputation".  Trust, as I understand it, is the probability
[0,1] that a given action in the future will be performed as
described.  Reputation is a summation of pervious data points to give
a score that can be used to to calculate trust.  Reputation is easier
to capture using machine readable data.  The algorithm to calculate
trust can be quite complex and will often use subjective factors,
based on users and groups.
