Lookup WebFinger:

All WebFinger links have a rel property that identifies the type of the link relation. Values can be URIs or a registered relation type. Any valid rel value can be used in WebFinger links.

The following rel values have been defined in the webfinger.net namespace to address common WebFinger use cases.


The link relation http://webfinger.net/rel/avatar identifies a person’s avatar and may be in any standard image format (e.g., PNG, JPEG, GIF).


The link relation http://webfinger.net/rel/profile-page identifies the main home/profile page that a human should visit when getting info about that webfinger account. It says nothing about the content-type (or microformats), but it’s likely text/html if it’s for users.
