NAME
XML::Atom::Service - Atom Service Document object
SYNOPSIS
use XML::Atom::Service;
use XML::Atom::Categories;
# use the new namespace, instead of old one 'http://purl.org/atom/app#'
#$XML::Atom::Service::DefaultNamespace = 'http://www.w3.org/2007/app';
my $categories = XML::Atom::Categories->new;
$categories->href('http://example.com/cats/forMain.cats');
$categories->add_category($category);
my $collection = XML::Atom::Collection->new;
$collection->href('http://example.org/reilly/main');
$collection->title('My Blog Entries');
$collection->categories($categories);
my $workspace = XML::Atom::Workspace->new;
$workspace->title('Main Site');
$workspace->add_collection($collection);
my $service = XML::Atom::Service->new;
$service->add_workspace($workspace);
my $xml = $service->as_xml;
## Get lists of the workspace, collection, and categories elements.
my @workspace = $service->workspace;
my @collection = $workspace[0]->collection;
my @categories = $collection[0]->categories;
## Get service document by using XML::Atom::Client
use XML::Atom::Client;
my $client = XML::Atom::Client->new;
my $service = $client->getService($service_uri);DESCRIPTION
For authoring to commence, a client needs to first discover the capabilities and locations of the available collections. Service Documents are designed to support this discovery process. They describe the location and capabilities of one or more Collection.
The Service Document is defined in "The Atom Publishing Protocol," IETF Internet-Draft.
METHODS
XML::Atom::Service->new([ $stream ])
Creates a new Service Document object, and if $stream is supplied, fills it with the data specified by $stream.
Automatically handles autodiscovery if $stream is a URI (see below).
Returns the new XML::Atom::Service object. On failure, returns undef.
$stream can be any one of the following:
Reference to a scalar
This is treated as the XML body of the feed.
Scalar
This is treated as the name of a file containing the Service Document XML.
Filehandle
This is treated as an open filehandle from which the Service Document XML can be read.
URI object
This is treated as a URI, and the Service Document XML will be retrieved from the URI.
$service->workspace
If called in scalar context, returns an XML::Atom::Workspace object corresponding to the first <workspace> element found in the Service Document.
If called in list context, returns a list of XML::Atom::Workspace objects corresponding to all of the <workspace> elements found in the Service Document.
$service->add_workspace($workspace)
Adds the workspace $workspace, which must be an XML::Atom::Workspace object, to the Service Document as a new <workspace> element. For example:
my $workspace = XML::Atom::Workspace->new;
$workspace->title('Foo Bar');
$service->add_workspace($workspace);$service->element_name
$service->element_ns
XML::Atom::Client::getService($service_uri)
Retrieves the service document at $service_uri.
Returns an XML::Atom::Service object representing the service document returned from the server.
USING NEW NAMESPACE
By default, XML::Atom::Service and other classes (Workspace, Collection and Categories) will create entities using old namespace, 'http://purl.org/atom/app#'. In order to use the new namespace, you can set namespace by setting $XML::Atom::Service::DefaultNamespace global variable like:
use XML::Atom::Service;
$XML::Atom::Service::DefaultNamespace = 'http://www.w3.org/2007/app';SEE ALSO
