The '''Common Data Format''' (CDF) is a scientific data file format and associated APIs designed by NASA for multi-dimensional datasets, and most commonly used in Heliophysics. CDF was designed and developed in 1984 by the National Space Science Data Center (NSSDC) at NASA/GSFC. CDF was originally written in FORTRAN, and rewritten in 1990 in C (version 2). In the mean time, [[netCDF]] was developed in C, based on the CDF conceptual model. Both models and existing software have matured substantially since, and share common goals. CDF libraries in Java, Python, and C++ have been developed independently, based on the [https://spdf.gsfc.nasa.gov/pub/software/cdf/doc/cdf381/cdf38ifd.pdf CDF Internal Formats Document]. Internal metadata generally follows the [https://github.com/IHDE-Alliance/ISTP_metadata ISTP Metadata Guidelines]. The NASA Planetary Data System (PDS) adopted CDF with some constraints as an archive standard {https://pds-ppi.igpp.ucla.edu/doc/CDF-A-Specification-v1.0.pdf CDF-A Specification], with a [https://pds-ppi.igpp.ucla.edu/doc/cdf/Guide-to-Archiving-CDF-Files-in-PDS4-v7.pdf Guide to Archiving CDF Files in PDS4].

The version 3 examples start with byte sequence <code>CD F3 00 01</code>, the middle ranged versions (2.6 and 2.7) begin with <code>CD F2 60 02</code> and
older versions 2.5 or earlier start with byte sequence <code>00 00 FF FF</code>.
