Five Models for Defining DataInformation, and Knowledge

1. UD: D-I; SD: K; meaning: D-I are external phenomena; K are internal phenomena. This is the most common one. It underlies the rationale of the name "Information Science"; that is, Information Science is focused on exploring data and information, which are external phenomena. It does not explore knowledge, which is internal phenomena. 

2. UD: D; SD: I-K; meaning: D are external phenomena; I-K are internal phenomena.  

3. UD: D-I-K; SD: I-K; meaning: D are external phenomena; I-K phenomena can be in both domains, external or internal. 

4. UD: D-I; SD: D-I-K; meaning: D-I  phenomena can be in both domains, external or internal; K phenomena are internal.

5. UD: D-I-K; SD: D-I-K; meaning: D-I-K phenomena can be in both domains, universal (i.e., external) or subjective (i.e., internal).
