codebook
Encryption key guide
A codebook is a reference document that pairs encoded signals with their meanings—originally used for translating messages in cipher or military communications.
In research, a codebook defines how data should be categorized or scored: The codebook specifies how to code each survey response.
The term suggests systematic, authoritative translation between one system and another.
