Abstract

   This specification defines the Webfinger protocol.  Webfinger may be
   used to discover information about people on the Internet, such as a
   person's personal profile address, identity service, telephone
   number, or preferred avatar.  Webfinger may also be used to learn
   information about objects on the network, such as the amount of toner
   in a printer or the physical location of a server.
