Really Simple Discovery
This is an archive of the RSD spec and related materials (as I find them and them and dig them out.)
Back in 2002 I was working on a desktop blog editor called Archipelago and started a page that collected all the info needed to start editing a blog for ech of the major platform at the time. It rapidly became tedious to maintain and update, and I realized that I could encode the information in a file and use that to guide folks. A did a sample file and realized that the real answer was to have that file a part of each platform so that when that developer decided to make changes, they just had to update a file in their own control. This follows the naturla pattern if distributing work to others :) as well as separation of concerns.
Fortuntely some of the blogging platform folks were willing to dive in and in a short time everyone supported RSD. A win for clients everywhere. Many thanks to all who helped.
