This paper proposes a set of distinctions that may be helpful for the classification and taxonomy of the various theories, approaches, ideas and definitions of the concept of information. It hopes to offer a place as neutral as possible to locate, compare, classify and discuss the quite large amount of those developments. The main benefit is to be able to clean up the discussion from dialogues that expend a lot of time and energy in getting at a name consensus, naming ideas or classes of entities, instead of discussing the deep nature of those ideas or entities.
The paper suggest that most known approaches may be expressed in terms of the underlying distinctions and concludes that after giving consensus names to those dis-tinctions, a unified information and knowledge theory may be build.
