Hixie's Natural Log: Pingback 1.0

We released the Pingback 1.0 Specification today. Is your Web log pingback-enabled?

Pingback was an idea originally thought up by Stuart Langridge and then developed by Simon Willson...

It basically boils down to telling a Web log when you've linked to it, by fetching the page, looking for a header advertising a pingback server, and then invoking an XML-RPC call on that server. The best thing about this idea is that unlike similar schemes like TrackBack, it is totally transparent to both users. It is also software-agnostic, so any Web logging system can implement pingback and interoperate with all other pingback-enabled Web logs.
