NAME

       XML::Atom::Service - Atom Service Document object

COMPATIBILITY ISSUES

       XML::Atom::Service has changed the default namespace since v0.15.0.  The new namespaces
       are 'http://www.w3.org/2005/Atom' and 'http://www.w3.org/2007/app'.

       See NAMESPACES in details.

SYNOPSIS

         use XML::Atom::Service;

         my $category = XML::Atom::Category->new;
         $category->term('joke');
         $category->scheme('http://example.org/extra-cats/');

         my $categories = XML::Atom::Categories->new;
         $categories->add_category($category);

         my $collection = XML::Atom::Collection->new;
         $collection->href('http://example.org/reilly/main');
         $collection->title('My Blog Entries');
         $collection->add_accept('application/atom+xml;type=entry');
         $collection->add_categories($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->workspaces;
         my @collection = $workspace[0]->collections;
         my @categories = $collection[0]->categories;

DESCRIPTION

       The Atom Publishing Protocol (Atompub) is a protocol for publishing and editing Web
       resources described at
       <http://www.ietf.org/internet-drafts/draft-ietf-atompub-protocol-17.txt>.

       XML::Atom::Service is an Service Document implementation.  In the Atom Publishing
       Protocol, a client needs to first discover the capabilities and locations of Collections.
       The Service Document is designed to support this discovery process.  The document
       describes the location and capabilities of Collections.

       The Atom Publishing Protocol introduces some new XML elements, such as app:edited and
       app:draft, which are imported into XML::Atom.  See XML::Atom::Atompub in detail.

       This module was tested in InteropTokyo2007
       <http://intertwingly.net/wiki/pie/July2007InteropTokyo>, and interoperated with other
       implementations.

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 Service Document.

       •   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 "app: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 app: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 app:workspace element. For example:

           my $workspace = XML::Atom::Workspace->new;
           $workspace->title('Foo Bar');
           $service->add_workspace($workspace);

   $service->element_name
   $service->element_ns

NAMESPACES

       By default, XML::Atom::Service will create entities using the new Atom namespaces,
       'http://www.w3.org/2005/Atom' and 'http://www.w3.org/2007/app'.  In order to use old ones,
       you can set them by setting global variables like:

         use XML::Atom;
         use XML::Atom::Service;
         $XML::Atom::DefaultVersion = '0.3';   # 'http://purl.org/atom/ns#'
         $XML::Atom::Service::DefaultNamespace = 'http://purl.org/atom/app#';
