Output Files

Under the 'extracted-monthly' directory, WikiMedia XML dump files (one for each month) are generated. The file month-<k>.xml corresponds to the extracted wiki articles for the kth month.

Notes

The range of months is hard-coded as January 2001 ~ December 2007 in org.mediawiki.dumper.LREMonthlyDumper20012007, and so is the output directory. Change these as necessary, or even better, parameterize them.
