Here are some different models: - some hierarchy, e.g. digital certificates with some master certificate at the top of the chain, built into software produces - peer-to-peer - the PGP model of authority - a distributed network of some sort, possibly weighted, and possibly needing multiple copies of the same assertion by different authorities - based in some standards. e.g. DNS, which provides for authoritative domain name records (I think) and hence can act as a basis for say authoritative metadata about http://example.org/example/dir but it's quite a lot of work to do so in a trustworthy way So authority is seen in the above as similar to validating a digital identity. Alternatively, we build on the notion of recognising someone as because they are. So we look at what some source of information is saying - if it is saying things that we know to be correct - or that we have reasonable evidence to be correct - then we increase our sense of that source being authoritative about information of that type.
