Abstract: In the course of designing a major mosaicked instrument (DEIMOS) we need tools to manage the large set of FITS keywords required for instrument control and data reduction/archiving. We have therefore constructed a relational database schema which describes FITS keywords, and have implemented it using Sybase. In this schema FITS keywords and structures are entities, having attributes such as format, units, data-type, minimum and maximum value, semantics, etc. The schema was expanded and generalized to document information flow and database schema (becoming self-referential). Many useful output products (documentation, diagnostics, configuration, and source code) can be generated from one authoritative source of keyword information.
