Integrating with a Content Management System to use the web feed utility

To use the web feed utility, you can integrate with any Content Management System that generates web feeds.

If you are using IBM Web Content Manager, packaged with WebSphere Portal, follow this procedure to configure IBM Web Content Manager, to generate web feeds. Creating feeds from IBM Web Content Manager is a two-step process:

Create a template for the feeds by creating and configuring a Menu Component.
Create sample data for feeds to output.

In this procedure, you use an example intranet site that is preinstalled with WebSphere Portal. The feed is managed by an Atom Feed Menu Component that creates an Atom feed for the existing site area. The feed is linked in the List presentation template. The Atom Feed Menu Component requires two 'CDATA' Text Components control rich text in the feed. To display your content on different pages, use a page URL mapping that refers to the page where the content is shown. Typically, design elements are stored in design library, but in this procedure you use the standard library 'Intranet 6.1.0' provided with the WebSphere Portal.

You can adapt this procedure to add feeds to other IBM Web Content Manager managed sites.

Procedure

Add an Atom feed to your existing website.
1. Using Mozilla Firefox, open http://portal.ibm.com:10040/wps/portal/intranet.
  
  This intranet home page that contains the latest news, announcement, and events. You add an Atom feed to Announcements section. People can subscribe to this list and use their favorite feed reader to receive updates on any new announcements.
  
  The page name is Intranet. Notice in the URL (http://portal.ibm.com:10040/wps/portal/intranet) that a Virtual Portal mapping of intranet exists for the page.
2. Log in first as an IBM Web Content Manager designer
3. Expand Applications > Content > Web Content Management.
  For example:
4. Change the library from default Internet Web Content 6.1.0 to Intranet Web Content 6.1.0. Go to the Content to verify that you have an Intranet site with a Home – Announcements site area. Notice the Announcement List that controls the list view, and two announcement entries Employee Achievements and Company Milestones.
  For example:
5. Go to the Home level; select Announcements; then, click Edit.
6. On the Announcements tab, Manage Elements
7. In the Element type list, select Short Text. In the Name field, type PageURLMapping. In the Display title field, type Page URL Mapping. Click Add; then, click OK.
8. In the Page URL Mapping field, type intranet. This portal page is where the announcements are shown. Click Save and Close. You can repeat this step for other site areas, News, and Events.
To add rich text to your feeds, put text into CDATA tags, <![Data[, and ]]>. Add the text in text components; then add the text components to the menu component.
1. Create a text component, click New > Component > Text.
2. Complete the fields:
  
  Name
  
  Type CData Start.
  
  Display title
  
  Type CData Start.
  
  Text Element
  
  Type <![CDATA[
  
  For example:
3. Add access to all users (including anonymous). Expand the Access section. In the Contributor User Defined list, select [all users].
4. Click Save to save the text component.
5. Click Save as to create another text component that is based on the one you created.
  Name this component CData End. In the Text Element field, type ]]>. For example:
6. Click Save and Close.

Create a menu component.

Click New > Component > Menu
In the Identification page, set the following options:
Identification section

Description

Menu that creates an Atom feed for an existing site area

Menu element query
Select:
- Site Areas
- Exclude current content from results
Further options
Select:
- Current content
- Merge selected site areas with included site areas
For example:

Add the following code in the header.


<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<feed xmlns="http://www.w3.org/2005/Atom" >
<title><IDCmpnt context="current" type="content" field="title"/></title>
<link href="<PathCmpnt type="base"/>
  <URLCmpnt context="current" type="content" mode="standalone"/>">
</link>
<updated><HistoryCmpnt context="current" type="content" field="lastmodifieddate" format="yyyy-dd-MM'T'hh:mm:ss'Z'"/></updated>
<author>
  <name><IDCmpnt context="current" type="content" field="authors" format="cn"/></name>
</author>
<id>
  <PathCmpnt type="base"/><URLCmpnt context="current" type="content" mode="standalone"/>
</id>
<generator uri="your_Web_Content_Management_site">Web Content Management</generator>

Where your_Web_Content_Management_site is the URI value for your IBM Web Content Manager site.

Based on the current context, the default content for a site area, it creates this example code:


<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<feed xmlns="http://www.w3.org/2005/Atom">
<title>Announcements List</title>
<link rel="self" 
 href="http://portal.ibm.com:10040/wps/myportal/intranet?WCM_GLOBAL_CONTEXT=
 /wps/wcm/myconnect/Intranet+Web+Content+6.1.0/IntranetSite/Home/Announcements/AnnouncementsList">
</link>
<updated>2008-06-24T12:24:57Z</updated>
<author>
  <name>uid=xyzadmin,o=defaultWIMFileBasedRealm</name>

<id>http://portal.ibm.com:10040/wps/myportal/intranet?WCM_GLOBAL_CONTEXT=
  /wps/wcm/connect/Intranet+Web+Content+6.1.0/IntranetSite/Home/Announcements/AnnouncementsList
</id>
<generator uri="your_Web_Content_Management_site">Web Content Management</generator>

Note: This code is separated across multiple lines for readability.

Where your_Web_Content_Management_site is the URI value for your IBM Web Content Manager site.

Enter the following code in Design for each menu search result:


<entry>
  <title type="text"><IDCmpnt context="autoFill" type="content" field="title"/></title>
  <link rel="alternate" type="text/html" 
   href="<PathCmpnt type="base"/><URLCmpnt context="autoFill" type="content" mode="standalone"/>">
  </link>
  <id><IDCmpnt context="autoFill" type="content" field="id" format="id"/></id>
  <published><WorkflowCmpnt context="autoFill" type="content" field="publishdate" 
   format="yyyy-dd-MM'T'hh:mm:ss'Z'"/></published>
  <updated><HistoryCmpnt context="autoFill" type="content" field="lastmodifieddate" 
   format="yyyy-dd-MM'T'hh:mm:ss'Z'"/></updated>
  <summary><Element context="autoFill" type="content" key="Summary"/></summary>
  <content type="image/jpeg"  src='<PathCmpnt type="base"/><Element context="autoFill" 
   type="content" key="Image" format="url" htmlencode="true"/>'></content>
  <category term="<ProfileCmpnt context="autoFill" type="content" field="categories"/>" ></category>
  <author>
    <name>
      <IDCmpnt context="current" type="content" field="authors" format="cn"/>
    </name>
  </author>
</entry>

Enter the footer in the code to end the feed:</feed>

For example:
Click Save. Notice that an ID is added to the component tags.

If this ID is not added, verify that the correct names were used for the components.
Allow this menu to be read by all users (including anonymous users). Expand the Access section and add [all users] to User-Defined users.
