NAME
       URI::data - URI that contains immediate data

SYNOPSIS
        use URI;

        $u = URI->new("data:");
        $u->media_type("image/gif");
        $u->data(scalar(`cat camel.gif`));
        print "$u\n";
        open(XV, "|xv -") and print XV $u->data;

DESCRIPTION
       The "URI::data" class supports "URI" objects belonging to the data URI
       scheme.  The data URI scheme is specified in RFC 2397.  It allows
       inclusion of small data items as "immediate" data, as if it had been
       included externally.  Examples:

         data:,Perl%20is%20good

         data:image/gif;base64,R0lGODdhIAAgAIAAAAAAAPj8+CwAAAAAI
           AAgAAAClYyPqcu9AJyCjtIKc5w5xP14xgeO2tlY3nWcajmZZdeJcG

       "URI" objects belonging to the data scheme support the common methods
       (described in URI) and the following two scheme-specific methods:

       $uri->media_type( [$new_media_type] )
           Can be used to get or set the media type specified in the URI.  If
           no media type is specified, then the default
           "text/plain;charset=US-ASCII" is returned.

       $uri->data( [$new_data] )
           Can be used to get or set the data contained in the URI.  The data
           is passed unescaped (in binary form).  The decision about whether
           to base64 encode the data in the URI is taken automatically, based
           on the encoding that produces the shorter URI string.
