Information and Meta-information

In Logic (Theory)

Def. 1: X is a situation iff P such that represent(P, X) – cf. mental situation
Def. 2: P is an information on X iff X,Y represent(P, X) not-represent(P, Y)
Def. 3: P is an absurd information iff P not-represent(P, X)

Def. 4: P is a trivial information iff P represent(P, X)
Def. 5: Π is a meta-information iff P is an information on X and Π is an information on P.

In Linguistics (Theory)

Meta-information is information about another information.
In utterance analysis, meta-information concerns attention (selecting) and predication (collecting).
Every information about another information is also information, however this information is of another sort than the information in question. In linguistics, the meta-informative status (of uttered chunks of information) is an utterance-specific feature of that information which is being predicated upon in speech acts. Introducing the distinction information vs. meta-information makes it is easy to define such famous concepts as Subject, Object and Predicate, on the one hand, and Topic, Focus, Comment and Background, on the other hand.
Thus, truth-conditional values (True/False) are proposition-specific while meta-informative status values (New/Old) are utterance-specific.

In Computer Science (Practice)

"Metainformation is information about information. For example, if a document is considered to be information, its title, location, and subject are examples of metainformation. This term is sometimes used interchangably with the term metadata. The new field of knowledge management (KM) was developed to create systematic and reliable ways to manage data, information, and knowledge..."

"Meta-information is characteristics or qualifiers of information, affecting a human’s (or behavior model’s) information processing, situation awareness, and decision-making..."
