Here's code to create a JSON file with an index of NLTK Corpora data.
The json file is in the form of a dictionary with package id as the key, followed by the following fields (values) as a large tuple:
pkid, pkname, pkauthor, pklanguages, pkurl, pkchecksum, pksize, pksubdir, pkunzip, pkunzipped_size, pkwebpage,
pkcontact, pklicense, pkcopyright, pknote, pksample
Need the GetUrl module for above to work:
