one of Metrics
One way of modelling Reputation Management.
Good summary at Meatball Wiki:TrustMetric - A system to rank individuals in an online community based on how much the community as a whole "trusts" each individual. A trust metric assigns an exact amount of trust to each identity. Thus it usually measures how much the community as a whole trusts that identity. (In contrast, a Web Of Trust system determines for each user the amount of trust they can place in someone.)
Advogato is the standard example.
