I have a friend who read my blog using my feed. And sometime he pings me for some problem with the feed, like a drop of all the article as new
|
|
|
|
{{<mastodon "https://social.lol/@robb/113854214799861227">}}

|
|
|

And after read some other post with the same problem ( [Robb Knight problem with feed reader](https://rknight.me/notes/202501190902/) [Kev other problem with feed reader](https://kevquirk.com/notes/20250528-1702?utm_source=fundor333.com&utm_medium=link&utm_campaign=blogging&ref=fundor333.com) ) I understand a little this: Atom is newer and superior than Rss.
|
|
|
|
## Atom vs Rss
|
|
|
|
Atom is the newer one, born after the RSS and after fix a lot of the RSS bugs like:
|
|
|
|
- You have a strict format for checking and validation in Atom
|
|
- RSS is simpler but less strict and it is riddled with ambiguities which lead to inconsistency of interpretation
|
|
- You have a unique id for the feed in Atom
|
|
|
|
The last one is the one I was searching...
|
|
|
|
## The Answer
|
|
|
|
The feed reader find the new feed (new because you change the url or you change the serverside code) and check:
|
|
|
|
- Atom Feed: the reader find the same ID so is the same feed
|
|
- RSS Feed: the reader don't find the ID and find something different not in the items part so it is a new one
|
|
|
|
So I add the JsonFeed and AtomFeed to the blog for give the reader multiple option for the feed!
