The \f(CW\*(C`URI::data\*(C'\fR class supports \f(CW\*(C`URI\*(C'\fR objects belonging to the \fIdata\fR
\&\s-1URI\s0 scheme.  The \fIdata\fR \s-1URI\s0 scheme is specified in \s-1RFC 2397.\s0  It
allows inclusion of small data items as \*(L"immediate\*(R" data, as if it had
been included externally.  Examples:
.PP
.Vb 1
\&  data:,Perl%20is%20good
\&
\&  data:image/gif;base64,R0lGODdhIAAgAIAAAAAAAPj8+CwAAAAAI

\&\f(CW\*(C`URI\*(C'\fR objects belonging to the data scheme support the common methods
(described in \s-1URI\s0) and the following two scheme-specific methods:
.ie n .IP "$uri\->media_type( [$new_media_type] )" 4
.el .IP "\f(CW$uri\fR\->media_type( [$new_media_type] )" 4
.IX Item "$uri->media_type( [$new_media_type] )"
Can be used to get or set the media type specified in the
\&\s-1URI.\s0  If no media type is specified, then the default
\&\f(CW"text/plain;charset=US\-ASCII"\fR is returned.
.ie n .IP "$uri\->data( [$new_data] )" 4
.el .IP "\f(CW$uri\fR\->data( [$new_data] )" 4
.IX Item "$uri->data( [$new_data] )"
Can be used to get or set the data contained in the \s-1URI.\s0
The data is passed unescaped (in binary form).  The decision about
whether to base64 encode the data in the \s-1URI\s0 is taken automatically,
based on the encoding that produces the shorter \s-1URI\s0 string.
