Business::ISBN::Data \- data pack for Business::ISBN
.SH SYNOPSIS
.IX Header "SYNOPSIS"
see Business::ISBN
.SH DESCRIPTION
.IX Header "DESCRIPTION"
You don't need to load this module yourself in most cases. Business::ISBN
will load it when it loads. You must use Business::ISBN 3.005 or later
because the data structure changed slightly to fix a bug with ISBN13
prefixes.
.PP
These data are generated from the \fIRangeMessage.xml\fR file provided by
the ISBN Agency. The distributed version matches the date in the version
for this module. You can retrieve this yourself at <https://www.isbn\-international.org/range_file_generation>.
This file is included as part of the distribution and should be installed
at \fI~lib/Business/ISBN/Data/RangeMessage.xml\fR.
.PP
If you want to use a different \fIRangeMessage.xml\fR file, you can set
the \f(CW\*(C`ISBN_RANGE_MESSAGE\*(C'\fR environment variable to the alternate location
before you load \f(CW\*(C`Business::ISBN\*(C'\fR. 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.
.PP
If the default \fIRangeMessage.xml\fR or your alternate one is not available,
the module falls back to data included in \fIData.pm\fR. However, that data
are likely to be older. If it does not find that file, it looks
for \fIRangeMessage.xml\fR in the current directory.
.PP
The data are in \f(CW%Business::ISBN::country_data\fR (although the "country"
part is historical). If you want to see where the data are from, check
\&\f(CW$Business::ISBN::country_data{_source}\fR.
.SS "Packaging this module"
.IX Subsection "Packaging this module"
The included \fIRangeMessage.xml\fR is in under \fIlib/\fR at the same level
as \fIData.pm\fR. The same data exist as the default data in the code, so
you don't need to pass along the distributed \fIRangeMessage.xml\fR.
However, you can include a newer \fIRangeMessage.xml\fR.
.PP
With PAR, you can add extra files to the archive with \f(CW\*(C`\-a\*(C'\fR. Put the
new file somewhere the module will find it (or use \f(CW\*(C`ISBN_RANGE_MESSAGE\*(C'\fR
to lead it there):
.PP
.Vb 1
\&        pp ... \-a \*(Aq..../RangeMessage.xml;RangeMessage.xml\*(Aq
.Ve
.PP
If you put the \fIRangeMessage.xml\fR in the current working directory of
the application, the module should find it.
.SS "Updating the default data"
.IX Subsection "Updating the default data"
In the repo, find the \fIexamples/make_default_data.pl\fR program. Run
that against the latest \fIRangeMessage.xml\fR:
.PP
.Vb 1
\&        % perl \-Ilib examples/make_default_data.pl RangeMessage.xml
.Ve
.PP
That produces the code you need to replace in the module. Check that
that data aren't weird: sometimes the group names have errors or
oddities. The program handles escaping single quotes and trimming
white space.
.SH "SOURCE AVAILABILITY"
