perl-Business-ISBN-Data

data pack for Business::ISBN

You don't need to load this module yourself in most cases. 'Business::ISBN' will load it when it loads. These data are generated from the _RangeMessage.xml_ file provided by the ISBN Agency. You can retrieve this yourself at the <a href="http://www.isbn-international.org/agency?rmxml=1">http://www.isbn-international.org/agency?rmxml=1</a> manpage. This file is included as part of the distribution and should be installed at _~lib/Business/ISBN/RangeMessage.xml_. If you want to use a different _RangeMessage.xml_ file, you can set the 'ISBN_RANGE_MESSAGE' environment variable to the alternate location before you load 'Business::ISBN'. This way, you can use the latest (or even earlier) data without having to install something new or wait for an update to this module. If the default _RangeMessage.xml_ or your alternate one is not available, the module falls back to data included in _Data.pm_. However, that data is likely to be older data. The data are in '%Business::ISBN::country_data' (although the "country" part is historical). If you want to see where the data are from, check '$Business::ISBN::country_data{_source}'.
