Question

I don't think this has been previously asked -- I want to provide an RSS service for part of a TWiki web. That is, I'd like to be able to specify a root topic in a web and have the RSS feed notify users of any changes or additions to that topic or any topic referenced in it, recursively. Yes, I know that's a bad word that invokes problems with the RSS search potentially looping infinitely. I suppose the easy thing to do would be to define some unique tag that would be included in any page that should be included in the RSS search, and then search on that tag -- but then I have to depend on the Pernicious Users remembering to include the tag when they add new topics to the tree, and of course one can never trust users. Any good ideas would be welcomed.

If you answer a question - or someone answered one of your questions - please remember to edit the page and set the status to answered. The status selector is below the edit box.

Not exactly what you want, but you can add a search parameter (with regex) to WebRss to get an RSS feed of a set of topics. That search could look for a common tag. See WebRssBase.

Yes, That's Plan B, but see the reference to Pernicious Users. I'm very not sure I can count on J. Random Account who might be creating a new page under my discussion topic to remember to include the search tag. And I don't want to be constantly checking up on them. Life is too short.

Assuming your application sets the parent, you can search for the parent topic to get notified of all discussion topics.

Something to add to the SearchPatternCookbook.
