---++ RSS Feed Usage

   * The URL for an RSS feed is =%SCRIPTURL{"view"}%/<web>/WebRss=
   * For this <nop>%WEB% web it is %SCRIPTURL{"view"}%/%WEB%/WebRss
   * You can also create a custom feed based on a search. Add a =search=value= parameter to the URL, e.g. %SCRIPTURL{"view"}%/%WEB%/WebRss?search=plugin is a what's new feed about Plugins.

---++ RSS Feed Internals

Each web has a WebRss topic which includes part of this <nop>%TOPIC% topic. This topic is the base for the RSS feed and generates an RSS 1.0 feed for TWiki:Codev/TWikiSyndication.

The WebRss topic in each web contains the following text:

-----
<pre>
&lt;channel rdf:about="%<nop>SCRIPTURL{"view"}%/%<nop>INCLUDINGWEB%">
  &lt;title>%<nop>WIKITOOLNAME%'s &lt;nop>%<nop>INCLUDINGWEB% web&lt;/title>
  &lt;link>%<nop>SCRIPTURL{"view"}%/%<nop>INCLUDINGWEB%&lt;/link>
  &lt;description>(the description of the web). TWiki is a Web-Based Collaboration Platform for the Enterprise.&lt;/description>
