Categories That Are Not Classifications
There are also compartments, using code words which pertain to specific projects and are used to more easily manage which individuals require certain information. Code words are not levels of classification themselves, but a person working on a project may have the code word for that project added to his file, and then will be given access to the relevant documents. Code words may also label the sources of various documents; for example, there are code words used to indicate that a document may break the cover of intelligence operatives if its content becomes known. The WWII code word Ultra identified information found by decrypting German ciphers, such as the Enigma machine, and which—regardless of its own significance—might inform the Germans that Enigma was broken if they became aware that it was known.

Famous quotes containing the word categories:
“The analogy between the mind and a computer fails for many reasons. The brain is constructed by principles that assure diversity and degeneracy. Unlike a computer, it has no replicative memory. It is historical and value driven. It forms categories by internal criteria and by constraints acting at many scales, not by means of a syntactically constructed program. The world with which the brain interacts is not unequivocally made up of classical categories.”
—Gerald M. Edelman (b. 1928)
