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.
