You may not know about it, but it want to replace the RSS format. The first version of new syndication format called JSONFeed was released on May 17, 2017.
JSONFeed authors have noticed that JSON has become the developers’ choice for APIs, and that developers will often go out of their way to avoid XML. JSON is simpler to read and write, and it’s less prone to bugs. They developed JSON Feed, a format similar to RSS and Atom but in JSON. It reflects the lessons learned from our years of work reading and publishing feeds.
A new format that we must follow in the next months.
If you are a PHP developer, I start to create a library to read and write JSONFeed content. It is available on Github. Feel free to contribute.
I have also updated my website to allow you to follow updates throw a JSONFeed.
