N-Dimensional Data Format

General description
Starlink NDF files are a hierarchical structuring format, primarily for astronomical data, developed by the UK Starlink Project (1980--2005), and based on the same project's SDF files.

Other information
The NDF format is documented in the Starlink project document SUN/33.

The Starlink Project ran from 1980 to 2005, and has been supported, since its funding ended, by the Joint Astronomy Centre, Hawai`i.

There is no standard NDF MIME type. Almost all NDF files used a  file extension.

Software
The Starlink software suite reads, writes and manipulates NDF files.
