SYNOPSIS
  use Bric::SOAP;

DESCRIPTION
This module serves as a root class for the Bric::SOAP classes. It also contains the functional and technical specifications for the Bricolage SOAP interface.

Functional Specification
The Bricolage SOAP interface expose key Bricolage systems to automation. This section describes intended functionality -- implementation details are described below in the Technical Specification section.

  Supported Functionality
The Bricolage SOAP interface supports the following features:

Stories and Media
    Clients can create new stories and media and update existing stories and media in the system. Clients can also export existing stories and media in the format accepted for creation. Finally, clients may delete stories or media.

Elements
    Clients can create, update, delete and export element definitions.

Templates
    Clients can create, update, delete and export templates.

Workflow
    Clients can move stories and media between desks. Clients can also publish stories and media and deploy templates.

  Use Cases
The functionality described above exposes a great deal power. Here are some potential use cases:

Importing Content From Legacy Systems
    Using the Story and Media interfaces, content can be moved from legacy CMS systems into Bricolage.

Automated Publishing
    With access to workflow and publishing, one can write an auto-publishing daemon that publishes a selection of stories on a schedule.

Story and Media Synchronization
    It is often desirable to move stories and media between instances of Bricolage. The SOAP interface can be used by a clients to automatically synchronize stories and media in a group of Bricolage instances. Synchronization can be made according to selection criteria similar to that exposed by the "list()" method in Bricolage classes.

Element and Template Distribution
    A centrally-developed library of elements and templates has many advantages. With the SOAP interface, one can automatically update Bricolage instances with new versions of elements and templates.

XML Syndication
    An XML syndication system can be written to pull stories from the SOAP interface and transform them into the target XML DTD. Syndication can also be accomplished using output channels and templates.

Technical Specification
This section describes the implementation of the Bricolage SOAP functional specification described above.

  Technologies

SOAP
    Bricolage provides a SOAP 1.1 compatible interface. See <http://www.w3.org/TR/SOAP> for the SOAP specification. The SOAP server uses use the SOAP::Lite (<http://www.soaplite.com>) for its SOAP implementation. Clients may use any SOAP 1.1 compatible library, although only SOAP::Lite clients have been tested during development.

XML Schema
    The format of XML documents used by the SOAP interface are specified in XML Schema format. See <http://www.w3.org/XML/Schema> for more information on this format. The schema is provided below.

  Modules
The following modules support the SOAP interface. See the documentation for each module for interface details, including XML Schemas and SOAP client examples.

Bric::SOAP::Handler
    This module provides the Apache/mod_perl SOAP handler. It is responsible for dispatching requests to individual Bric::SOAP modules.

Bric::SOAP::Auth
    Handles authentication for SOAP clients. Authentication will be cookie-based -- clients can call a "login()" function and get an HTTP cookie to use with calls to the other SOAP interfaces.

Bric::SOAP::Story
    Provides query, export, update, create, and delete for Story objects.

Bric::SOAP::Media
    Provides query, export, update, create, and delete for Media objects.

Bric::SOAP::Template
    Provides query, export, update, create, and delete for Templates.

Bric::SOAP::Element
    Provides query, export, update, create, and delete for Element definitions.

Bric::SOAP::Category
    Provides query, export, update, create, and delete for Category objects.

Bric::SOAP::MediaType
    Provides query, export, update, create, and delete for MediaType objects.

Bric::SOAP::Site
    Provides query, export, update, create, and delete for Site objects.

Bric::SOAP::Keyword
    Provides query, export, update, create, and delete for Keyword objects.

Bric::SOAP::User
    Provides query, export, update, create, and delete for User objects.

Bric::SOAP::Desk
    Provides query, export, update, create, and delete for Desk objects.

Bric::SOAP::Workflow
    Provides the ability to move Story, Media and Formatting objects between desks. Also provides checkin, checkout, publish, and deploy. And now list_ids, export, create, update, and delete.

  SOAP Details
All of the Bricolage SOAP modules described above share a common SOAP serialization strategy described here.

Namespace
    The namespace for all Bric::SOAP calls is:

      http://bricolage.sourceforge.net

    To specify a module within that namespace, append the pieces as path components. For example, to call methods in Bric::SOAP::Story use the namespace:

      http://bricolage.sourceforge.net/Bric/SOAP/Story

    For the SOAP::Lite users in the audience, this is the "uri" setting.

Parameters
    All Bric::SOAP methods use a named-parameter style call syntax. This syntax is mapped to XML elements where the name is the name of the element and the value is the value contained inside the element. For example, a Perl call like:

       Bric::SOAP::Story->list_ids({ title => '%foo%', publish_status => 1 });

    Is called through SOAP as:

      <SOAP-ENV:Body>
        <namesp2:list_ids
         xmlns:namesp2="http://bricolage.sourceforge.net/Bric/SOAP/Story">
          <title xsi:type="xsd:string">%foo%</title>
          <publish_status xsi:type="xsd:int">1</publish_status>
        </namesp2:list_ids>
      </SOAP-ENV:Body>

    SOAP::Lite clients can generate this call using "SOAP::Data::name()" to name the parameters:

      import SOAP::Data 'name';
      my $result = $soap->list_ids(name(title          => '%foo%'),
                                   name(publish_status => 1)       );

    In most cases, Perl doesn't distinguish between strings and numbers. When writing a SOAP client you should feel free to type your parameters in whatever way makes most sense in your implementation language.

Return Values
    All Bric::SOAP methods return a single named parameter. If a method needs to return multiple values then a SOAP array is returned containing the values. For example, "Bric::SOAP::Story->list_ids()" returns a list of story IDs in this structure:

      <namesp2:list_idsResponse
       xmlns:namesp2="http://bricolage.sourceforge.net/Bric/SOAP/Story">
        <story_ids SOAP-ENC:arrayType="xsd:int[4]" xsi:type="SOAP-ENC:Array">
           <story_id xsi:type="xsd:int">1027</story_id>
           <story_id xsi:type="xsd:int">1028</story_id>
           <story_id xsi:type="xsd:int">1029</story_id>
           <story_id xsi:type="xsd:int">1030</story_id>
        </story_ids>
      </namesp2:list_idsResponse>

    And an empty response returns an empty array:

      <namesp1:list_idsResponse
       xmlns:namesp1="http://bricolage.sourceforge.net/Bric/SOAP/Story">
        <story_ids SOAP-ENC:arrayType="xsd:ur-type[0]" xsi:type="SOAP-ENC:Array"/>
      </namesp1:list_idsResponse>

    SOAP::Lite clients can access this return value as an array reference:

      my $story_ids = $response->result;
      foreach my $id (@$story_ids) {
          frobnicate($id);
      }

XML Document Encoding
    The Bric::SOAP system uses complete XML documents as parameters and return values to many methods ("create()" and "export()", for example). These documents must be encoded in Base64 for performance reasons. See the PERFORMANCE section of the SOAP::Lite documentation for a full explanation of why this is necessary. This is not a limitation of SOAP::Lite in particular but the explanation is particularly lucid.

    For SOAP::Lite clients, generating Base64 parameters is very easy:

       my $document = name(document => $xml)->type('base64');

    And on decoding, returned base64 will be done automatically.

    The XML Schema for these documents is included below.

Error Handling
    Errors are returned as SOAP faults using fault strings produced by the method called. If you use SOAP::Lite as your client library you can check for errors using the "fault()" method and access the error message with "faultstring()":

      my $response = $soap->list_ids(...);
      die "SOAP Error: " . $response->faultstring if $response->fault;

XML Schema For Asset Documents
    This is the XML Schema for asset documents used in the Bricolage SOAP interface. A pretty-printed version complete with colorful graphs generated by XMLSpy can be found at <http://bricolage.cc/soap_schema/assets.html>.
