Prolog source for CF-metadata Standard Names grammar

This page contains the actual Prolog grammar rules for CF-metadata "standard names".  

This is actually the master copy, which can be accessed by Prolog programs using an http library.    Therefore, if you have edit permissions for this page, please change the content below the horizontal line only of you know what you are doing!
