There are five different layers in the Cognitive Model. (See xapend.i_cog_model). Each piece of “data” used within a DIDO can be classified accordingly. For example, the number of cents in a dollar might be classified as Data. Note: to help differentiate the generic, general, all encompasing use of “data” from the specific cognitive “Data”, the cognitive layer is referred to with an Tite case (i.e., first letter is capitalized).

Stavros and Albrant ¹⁾ define the five layers of the Cognitive Model as follows:

Figure 1: Cognitive Model

1. Data - Data that is a raw concept; it simply exists and has no significance beyond its existence (in and of itself). It is the basis upon which Information concepts are built
2. Information - A concept aggregating data concepts together, in other words, Data that has been given meaning by way of relational connection
3. Knowledge - A concept relating appropriate collection of Information concepts together, such that it's intent is useful
4. Understanding - An interpolative and probabilistic concept that reflects Wisdom concepts
5. Wisdom - An extrapolative and nondeterministic, non-probabilistic concept which is built upon Understanding concepts.

The flow between the cognitive layers is bidirectional and can have many-to-many relationships. For example, any particular Wisdom concept can be associated with any number of Understanding concepts. The inverse is also true; Understanding concepts can also be used to help support any number of Wisdom Concepts.

Facts are not by themselves potected under U.S. Copyright law. For example, you can not copyright the temperature recorded outdoors. While the U.S. does provide some protection of data (i.e., facts) as they are organized into a datastore (i.e., databases) ²⁾, the European Union under provides no protrction of data under the Directive 96/9/EC ³⁾

In the United States, facts by themselves are not protected by copyright. Therefore, data, as a collection of facts, is not protected by U.S. copyright law.

Databases as a whole can be protected by copyright as a compilation, but only under certain conditions. The first is that mere collection of data is not enough. The arrangement and selection of data must be sufficiently creative or original.⁴⁾
