Additionally, the link https://adif.org.uk/ADIF_Current will respond directly with the most recent released version of the ADIF Specification HTML file without a redirection.

Applications

Applications that want to access the most recent ADIF-related files (such as XML schemas) can read the text file adiflatestrelease.txt, which contains the version number of the most recent release as a 3-digit number, e.g. 316 represents ADIF Version 3.1.6.  (For reliability and performance, please download and use copies of the schema files.)

This can be used to construct the file names.  For example, the ADIF Version 3.1.6 ADX XML schema files are named:
 
316/adx316.xsd
316/adx316generic.xsd
