Cosma provides access to content resources organized around these basic elements of a Communication System: Media (channel), Knowledge (message), Human (sender/receiver) and Noise (interference). See also Outline (Site Map)

In addition, Cosma tends to focus on “Knowledge” resources.

The “DIKW Hierarchy”, also known variously as the “Wisdom Hierarchy”, the “Knowledge Hierarchy”, the “Information Hierarchy”, and the “Knowledge Pyramid”, refers loosely to a class of models for representing structural and/or functional relationships between the content of communication (data, information, knowledge, and wisdom). — Wikipedia

Most writers about the hierarchy refer to this passage from T. S. Eliot’s The Rock.

Where is the Life we have lost in living?
Where is the wisdom we have lost in knowledge?
Where is the knowledge we have lost in information? — T.S. Eliot, The Rock

Russell Ackoff popularized the hierarchy to categorize the content of communication.
From data to wisdom (Russell L. Ackoff, Journal of Applies Systems Analysis)
The wisdom of the world: Messages for the new millennium (Russell L. Ackoff, The Futurist)
On passing through 80 (Russell L. Ackoff, Systemic practice and action research)

Knowledge is a familiarity with someone or something, that can include descriptions, facts, information, and/or skills acquired through experience or education. It can refer to both the theoretical or practical understanding of a subject. It can be implicit (as with practical skill or expertise) or explicit (as with the theoretical understanding of a subject); and it can be more or less formal or systematic. In philosophy, the study of knowledge is called epistemology, and the philosopher Plato famously defined knowledge as “justified true belief.” There is however no single agreed upon definition of knowledge, and there are numerous theories to explain it. — Wikipedia
