1.  Introduction

   This document specifies a protocol which provides a way for the
   operator of a domain name to publish their contact information in a
   discoverable and machine-readable format.

   It serves as a complementary service to WHOIS ([RFC3912]) and RDAP
   ([RFC7480]), and differs in that it relies on self-publication by the
   domain operator, rather than a centralised third party service.

1.1.  Conventions Used in This Document

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].

2.  WHOAMI Protocol

   Domain Operators MAY publish a WHOAMI Record in conformance with this
   specification.  It may be published (a) at a URL indicated by a URI
   record [RFC7553] published in the DNS (as described in Section 2.1),
   or (b) at a well-known URL (as described in Section 2.2).

   Software which consumes WHOAMI records SHOULD first perform a DNS
   query for the URI record for a domain, falling back to the well-known
   URL if the query does not return a positive result.

2.1.  URI Record

   Domain Operators MAY publish the URL of their WHOAMI record as a URI
   record in the DNS.  An example of such a record is below:

   $ORIGIN example.com.
   _nicname._tcp IN URI 10 1 https://example.com/whoami/whoami.vcf

   Note: the Owner Name, Priority, Weight, Target and URI in the above
   record are illustrative only.

   The Service Tag of the URI record is constructed as per Section 4.1
   of [RFC7553], with the "_nicname" tag being derived from the "Who Is
   Protocol" entry in the "Service Name and Transport Protocol Port
   Number Registry (see [RFC6335]).
