Everything depends upon the context..
Documentation & knowledge. A oft repeated question / assertion in KM is the link between explicit documentation and knowledge. The point I'm trying to make, is documentation alone does not = knowledge. To retain knowledge against attrition you have to have a community… [Knowledge-at-work]
I have formed the view that it is intrinsic to knowledge that it be actionable. By this I do not mean that it necessarily provokes action, but that it enables it.

Everything depends upon the context. [Curiouser and curiouser!]
