How to Find out What's New?

There are three ways to find out what's new in each TWiki web:

1. WebChanges shows recent changes
2. People subscribed in WebNotify get notified of recent changes by e-mail
3. A news feed can be exported in RSS 1.0 format for TWiki:Codev/TWikiSyndication. RSS news readers like TWiki:Plugins/HeadlinesPlugin can display the recent changes

RSS Feed Usage

• The URL for an RSS feed is http://maxine.harmeny.com/twiki/bin/view/<web>/WebRss?skin=rss
• For this TWiki web it is http://maxine.harmeny.com/twiki/bin/view/TWiki/WebRss?skin=rss (or http://maxine.harmeny.com/twiki/bin/view/Main/WebRss?skin=rss&contenttype=text/plain for plain text RSS)
• You can also create a custom feed based on a search. Add a search=value parameter to the URL, e.g. http://maxine.harmeny.com/twiki/bin/view/TWiki/WebRss?skin=rss&search=plugin is a what's new feed about Plugins.

RSS Feed Internals

Each web has a WebRss topic which includes part of this WebRssBase 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:

<channel rdf:about="%SCRIPTURL%/view%SCRIPTSUFFIX%/%INCLUDINGWEB%">
  <title>%WIKITOOLNAME%'s %INCLUDINGWEB% web</title>
  <link>%SCRIPTURL%/view%SCRIPTSUFFIX%/%INCLUDINGWEB%</link>
  <description>(the description of the web). TWiki is a Web-Based Collaboration Platform for the Corporate World.</description>
%INCLUDE{"%TWIKIWEB%.WebRssBase"}%

Below part is included by each WebRss topic:
