NAME

       URI::data - URI that contain 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] )
           This method 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] )
           This method 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 auto-
           matically based on what encoding produces the shortest URI string.
