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">}}
{{<mastodon "https://mastodon.social/@andreagrandi/113854638640440084" >}}
And after read some other post with the same problem ( Robb Knight problem with feed reader Kev other problem with feed reader ) 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!
