I just want to share the article which distinguishes the technical differences between Atom vs. RSS Feed.
Until Atom feed, everyone was using RSS to syndicate content online. However, there was a group of people who analyzed RSS and found out that it’s not perfect and that the changes can be made. Community members could not do any changes to the RSS format. First of all, it was not open standard. And second of all, RSS 2.0 was copyrighted by Harvard University, which stated that no significant changes can be made to this format.
Please find the article in the below link.
