NAME
URI::duri - the duri URI scheme

SYNOPSIS
my $uri = URI->new('duri:2012:http://tobyinkster.co.uk/');
say $uri->embedded_uri;

DESCRIPTION
The dated URI scheme is defined in an Internet Draft
<http://tools.ietf.org/html/draft-masinter-dated-uri-10>. Dated URIs
include a date and an embedded URI. They identify the same resource that
was identified by the embedded URI at the given date.

This module brings support for the duri URI scheme to the URI framework.

Constructor
The constructor can be called in two forms:

`new($string)`
`new(\%hash)`

When called with a string argument, must be a URI string conforming to the
dated URI Internet Draft.

If called with a hashref argument, the hash must have a key `embedded_uri`
which is a string or URI object. It may have a key `datetime_string` which
is a string representing a datetime in the format required by the dated
URI specification; alternatively it may have a key `datetime` which is a
DateTime or (better) DateTime::Incomplete object; if neither are present,
then the current time is used instead.

Methods
The following accessors are provided:

`datetime`
`datetime($object)`
Get/set the URI's datetime as a DateTime::Incomplete object.

`datetime_string`
`datetime_string($string)`
Get/set the URI's datetime as a literal string.

`embedded_uri`
`embedded_uri($uri)`
Get/set the embedded URI as a URI object. (The setter may also be
called with a plain string.)

The following methods are inherited from URI and make sense to use:

`scheme`
`scheme($string)`
Get/set the URI scheme.

`as_string`
Get the URI as a string.

`as_iri`
Get the URI as a Unicode string.

`canonical`
Get the URI as a canonical string.

`secure`
Returns false, though the method doesn't make much sense. One URI is
no more secure than another; it is protocols that can be secure or
insecure.

`eq($uri)`
Tests if this URI is equal to another.

The following methods are also inherited from URI, but don't make much
sense to use: `opaque`, `path`, `fragment`. It generally makes more sense
to inspect the embedded URI:

say $duri->embedded_uri->fragment;
