What is the Difference Between RSS and RSS2?

🆚 Go to Comparative Table 🆚

RSS (Really Simple Syndication) is a popular web feed format used for publishing frequent updates, such as news and multimedia, in a standard format. RSS2 is the latest version of RSS, which introduced significant changes and improvements over its predecessors. The main differences between RSS and RSS2 include:

  1. Enclosures: RSS2 introduced support for enclosures, which was not present in RSS. This feature made RSS2 the most popular feed type for podcasting.
  2. Namespaces: RSS2 uses an explicit extension mechanism with XML namespaces, while RSS does not.
  3. Backward Compatibility: RSS2 is backward-compatible with earlier versions of RSS, meaning that it can understand and process RSS feeds from previous versions.
  4. Full Text Support: RSS2 does not support full text with a synopsis, whereas RSS uses markup as an extension for this purpose.
  5. Market Share: RSS holds a 17% market share, while RSS2 accounts for 67% of the market.

In summary, RSS2 is the latest and more advanced version of RSS, offering improved features and compatibility with various content types, such as podcasts. RSS2 is more widely used than the original RSS format, making it the preferred choice for content publishers and syndicators.
