Atom Syndication

Atom is a new syndication format, somewhat like RSS but solving some of its problems. It's been adopted by Google and has a number of benefits - see the Motivation page on the Atom wiki.

ATOM Feeds of Recent Changes of TWiki.org Webs

First version is now implemented on TWiki.org. Please help test it out with your preferred news reader. Point your reader to WebAtom, located in every web.

How to Establish ATOM Feeds on my own TWiki Site

1. Copy the raw text of TWiki.WebAtomBase and TWiki.WebAtom to your own site, using identical topic names
2. Copy view.rssatom.tmpl.txt to the twiki/templates directory; rename to view.rssatom.tmpl
3. If you are concerned about ATOM feed validation, apply patchisodate.txt patch to twiki/lib/TWiki.pm (most news readers probably are OK without the patch)
4. Create a WebAtom topic in every web you need an ATOM feed, content is described in TWiki.WebAtomBase

Now that TWiki can display ATOM feeds with with HeadlinesPlugin, we have one more step to go to have two way syndication:

I have not looked at the spec of ATOM, but it looks like this is a small feature enhancement for TWiki. The basics is already there with WebRssBase and WebRss. Those topics can be cloned and modified for WebAtomBase and WebAtom. Any volunteers?

For a change I wanted to do something fun and new, so I created the ATOM feeds. It is a plain port of the WebRssBase concept. The ATOM DTD has many bells and whistles, a more intelligent feed could be produced.

I'm certainly going to be playing with it, I'll submit what I think is half-way decent here.

well, here's a really mangled GluePlugin parsed version of it: http://simonraven.nuit.ca/bin/view/TWiki/WebAtomBase

and the tmpl:

<?xml version="1.0" encoding="% CHARSET %"?> <feed xmlns="http://www.w3.org/2005/Atom" xhtml="http://www.w3.org/1999/xhtml" s="http://www.ascc.net/xml/schematron"> % TEXT % </feed>

I just added the extra namespaces for xhtml and 's', ripped it from the rfc (RFC:4287) for the tmpl, and added a bunch of stuff in WebAtomBase ; as to the GluePlugin stuff, just remove the '*~~' '~~~' %~~' (and s/%~~~ /%/ FYI).

Oh, BTW, I didn't mean to imply that the one that came with the SVN from a few days ago isn't good, I just tend to play with things :).

ok, finally got something rather nice. added a few things. note i'm pulling this from my Blog/RenderAtom topic which MichaelDaum and I worked on together (he put in the final working bits and made it validate - thanks MD), which makes use of BlogPlugin 's WebDB .pm; it can easily be adapted to a %SEARCH or such. see RenderAtom in BlogPlugin from current SVN.

Is there already a solution for selective full content page feeds in TWiki. To be exactly, many feeds in the web contain the full text including css formating. Is there such a solution for TWiki or a plugin. If so, it should be mentioned on this site. If we had such a solution, we could even provided formated changes/history feeds of a topic's content.
