/c/en/music/n is explained the doc (https://github.com/commonsense/conceptnet5/wiki/URI-hierarchy) as:
"the initial /c to make it a concept, a part that indicates its language (usingthe BCP 47 language code for that language), and a part with the concept text. An optional fourth component gives the part of speech (as a single letter, following the convention of WordNet)."
But couldn't find documentation for the part
/wn/communication. Could you point to the documentation for this or explain this part of URI .. Thanks
