The input syntax for xmds is based on XML, which is administered by http://www.W3.org and the XML 1.0 recommendation may be found at http://www.w3.org/TR/2000/REC-xml-20001006.

xmds also uses the FFTW (Fastest Fourier Transform in the West) libraries. These may be found at http://www.fftw.org.

The ascii ouput data format is a subset of XSIL (eXtensible Scientific Interchange Language, which in turn is a subset of XML). This was derived by a group at Caltech: http://www.cacr.caltech.edu/SDA/xsil/index.html
