Really Simple Discovery
From Wikipedia, the free encyclopedia
Really Simple Discovery (RSD) is an XML format and a publishing convention for making services exposed by blog, or other web software, discoverable by client software. It is a way to reduce the information required to set up editing/blogging software to three well known elements:
Any other critical settings should either be defined in the RSD file related to the blog, or discoverable using the information provided.

[edit] History
RSD was proposed by Daniel Berlinger in the Really Simple Discoverability 1.0 specification.
[edit] Format
To make use of RSD, the owner of a site places a link tag in the head section of the homepage which indicates the location of the RSD file. An example:
<link rel="EditURI" type="application/rsd+xml" title="RSD" href="http://wherever the rsd.xml lives." />
If this tag is missing or the file is not found, clients should look in the default location which is a file named rsd.xml in the webroot.[1] For example:
http://example.com/rsd.xml
