RSS Feeds - Functional specification

* Excluding WordPress' "comment feeds".

Default settings

The default prefix setting ("Content to put before each post in the feed") is blank/empty.

The default suffix setting ("Content to put after each post in the feed") is The post %%POSTLINK%% appeared first on %%BLOGLINK%%..

Replacement variables

The following variables are available, and are automatically replaced in the generated prefix/suffix.

Variable	Description
%%AUTHORLINK%%	A link to the archive for the post author, with the author's name as anchor text.
%%POSTLINK%%	A link to the post, with the title as anchor text.
%%BLOGLINK%%	A link to your site, with your site's name as anchor text.
%%BLOGDESCLINK%%	A link to your site, with the site's name and description as anchor text.

Indexing & canonical URLs

Depending on the type of feed, additional HTTP headers must be set:

• Feeds representing content (posts, pages or taxonomies) should set a canonical URL of the 'parent' URL, via a link header.
• Feeds represending comments on content should set a meta robots directive of noindex, follow, via an x-robots-tag header.
