RSS Feed和Atom Feed

Keywords: Feeds, RSS, Atom

一直以来, 对于Blog的Feed都是一知半解的. 今天浏览了一下Feed的Wiki(http://en.wikipedia.org/wiki/Web_feed), 摘抄了几句.

A web feed is a data format used for providing users with frequently updated content. Content distributors syndicate a web feed, thereby allowing users to subscribe to it. Making a collection of web feeds accessible in one spot is known as aggregation, which is performed by an Internet aggregator. A web feed is also sometimes referred to as a syndicated feed.

Aggregator 也叫做 Feed Reader.

Feed目前有RSS和Atom两种流行机制, 其中RSS相对更加流行, 不过RSS的各个版本, 存在兼容性问题, 同时基于RSS的Web Syndication比较复杂. 所以Atom应运而生, Atom是基于XML的.
