Chapter 3. The Main Standards

The nice thing about standards is that there are so many of them to choose from.

Andrew S. Tanenbaum

In this short chapter, we will summarize the most commonly used XML syndication standards, namely:

• RSS 0.91

• RSS 0.92

• RSS 2.0 and modules

• RSS 1.0 and modules

With these four main threads, each expanded on in later chapters, we run the entire gamut of syndication possibilities: from the simple "channel and 15 URLs" of RSS 0.91 to the "unlimited number of entire articles and massive amounts of metadata" combination of RSS 1.0 and modules.
