I realize these definitions aren't much use without examples to illustrate them, so I'm inviting people to offer scenarios/things to be used for pointing out which aspect of the scenario/thing relates to which information aspect.
I've found that exchanging examples like this is an easy way to get pretty much anyone to understand information aspects in one on one conversations, but so far haven't really tried this in the forum. Let's give it a shot.
