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.
