In the Foskett Data->Information->Knowledge->Wisdom pyramid information is data which has been "organised by the relations of one to another into systems of ideas...The distinction is real because the process of organising is real and requires a conscious mental activity. It is possible because we have the power of the imagination: we can convert the isolated percepts into organised concepts, and this is the secondary stage of cognition" [foskett_fruitful]. Information then is data which has been processed in some sense to create an overview: This is the fourth blue dog I have seen in this museum today. Synthesizing information leads to knowledge.
