Webfinger (and simple-web-discovery) for WordPress!
Enables WebFinger (RFC 7033) support for WordPress.
About WebFinger:
WebFinger is used to discover information about people or other entities on the Internet that are identified by a URI using standard Hypertext Transfer Protocol (HTTP) methods over a secure transport. A WebFinger resource returns a JavaScript Object Notation (JSON) object describing the entity that is queried. The JSON object is referred to as the JSON Resource Descriptor (JRD).
(quote from the RFC)
FAQ
How to extend the JRD file
You can add your own links or properties like that:
function oexchange_target_link( $array ) {
$array["links"][] = array( 'rel' => 'http://oexchange.org/spec/0.8/rel/resident-target',
'href' => 'http://example.com',
'type' => 'application/xrd+xml' );
return $array;
}
add_filter( 'webfinger_data', 'oexchange_target_link' );
Add alternate file/output formats
You can add your own links or properties like that:
function render_xrd($webfinger) {
// set custom header();
// JRD to XRD code
exit;
}
add_action( 'webfinger_render', 'render_xrd', 5 );
