I’ve read your article, this was very informative, thanks you !
There is another way to make a feed reachable for feed reader : simply add a tag $:/tags/RawMarkup
With this the content of the tiddler is embeded in the head of the document and become reachable
@saqimtiaz in a similar application I used the filter that you would use to generate the items for the RSS feed, as the conditions for displaying a button to do the upload (in my case to print a PDF).
However if RSS entries are related to a date, the act of triggering the upload can also record the “last” upload. Subsequently the button can test if fresh content is available for upload. Basically a version of the “dirty” indicator.
Alternatively clicking save button on a “post” could trigger an action to test if an RSS file upload is required.
I hope someone can publish a “Finished” solution addressing this thread;
