DESCRIPTION

18       The "URI::data" class supports "URI" objects belonging to the data URI
19       scheme.  The data URI scheme is specified in RFC 2397.  It allows
20       inclusion of small data items as "immediate" data, as if it had been
21       included externally.  Examples:
22
23         data:,Perl%20is%20good
24
25         data:image/gif;base64,R0lGODdhIAAgAIAAAAAAAPj8+CwAAAAAI

31       "URI" objects belonging to the data scheme support the common methods
32       (described in URI) and the following two scheme-specific methods:
33
34       $uri->media_type( [$new_media_type] )
35           Can be used to get or set the media type specified in the URI.  If
36           no media type is specified, then the default
37           "text/plain;charset=US-ASCII" is returned.
38
39       $uri->data( [$new_data] )
40           Can be used to get or set the data contained in the URI.  The data
41           is passed unescaped (in binary form).  The decision about whether
42           to base64 encode the data in the URI is taken automatically, based
43           on the encoding that produces the shorter URI string.
