Syndication

Just like RSS. Except…

The article or “post” is written (i.e., on a blog)

The blog automatically creates a “feed” and makes it available on the Web

You use a “feed reader” to subscribe to the feed

You see updated headlines to your subscribed feeds in your feed reader

Article or “post” is written Article appears in your feed reader

“Fee

d” is

avai

lable

on the

Web

You use feed reader

to subscribe to the

feed

A little history…

1997 – Dave Winer (software developer) develops an XML-based web syndication format for his blog, Scripting News

1999 - Netscape also experimenting at this time – RDF Site Summary and later, incorporating parts of Winer’s format

2000 – RSS 1.0 developed

2002 – RSS 2.0 developed (Winer assists)

2003 – RSS 2.0 specification released

keyMake it simple! Preselected

feeds, etc.

Feed overload!

Can be a problem

Easy to subscribe to

too many feeds
