424 - RSS/Atom Feed

Basic Information

Product Description

RSS (Really Simple Syndication) and Atom are two XML-based standard formats for content subscription and distribution. They allow users to track updates from websites, blogs, podcasts, and more by subscribing to feeds, eliminating the need to actively visit the sites. RSS 2.0 is the most widely used version, with WordPress defaulting to RSS and the podcast industry almost entirely relying on RSS 2.0. Atom, standardized by IETF in RFC 4287, offers stricter specifications and better interoperability.
