ICANN RDAP Common

This is a common component library for the Registration Data Access Protocol (RDAP) written and sponsored by the Internet Corporation for Assigned Names and Numbers (ICANN). RDAP is standard of the IETF, and extensions to RDAP are a current work activity of the IETF's REGEXT working group. More information on ICANN's role in RDAP can be found here. General information on RDAP can be found here.

Installation

Add the library to your Cargo.toml: cargo add icann-rdap-common.

This library can be compiled for WASM targets.

Usage

Parse RDAP JSON:

use icann_rdap_common::prelude::*;

let json = r#"
  {
    "objectClassName": "ip network",
    "links": [
      {
        "value": "http://localhost:3000/rdap/ip/10.0.0.0/16",
        "rel": "self",
        "href": "http://localhost:3000/rdap/ip/10.0.0.0/16",
        "type": "application/rdap+json"
      }
    ],
    "events": [
      {
        "eventAction": "registration",
        "eventDate": "2023-06-16T22:56:49.594173356+00:00"
      },
      {
        "eventAction": "last changed",
        "eventDate": "2023-06-16T22:56:49.594189140+00:00"
      }
    ],
    "startAddress": "10.0.0.0",
    "endAddress": "10.0.255.255",
    "ipVersion": "v4"
  }
"#;

let rdap: RdapResponse = serde_json::from_str(json).unwrap();
assert!(matches!(rdap, RdapResponse::Network(_)));

Create some RDAP objects:

use icann_rdap_common::prelude::*;

// create a simple entity to be used inside other objects with builder().
let holder = Entity::builder().handle("foo-BAR").build();

// create an RDAP domain response object with response_obj()
let domain = Domain::response_obj()
  .ldh_name("example.com")
  .extension(ExtensionId::IcannRdapResponseProfile1.as_ref())
  .extension(ExtensionId::IcannRdapTechnicalImplementationGuide1.as_ref())
  .notice(Notice::builder()
    .title("Inaccuracy resport")
    .description_entry("Things may be wrong. But it isn't our fault.")
    .description_entry("Read the policy for more information.")
    .build()
  )
  .entity(holder.clone())
  .build();

// create an IP network to be used as a response with response_obj()
let net = Network::response_obj()
  .cidr("10.0.0.0/16")
  .entity(holder.clone())
  .extension(ExtensionId::NroRdapProfile0.as_ref())
  .notice(Notice::builder().title("test").build())
  .build()
  .unwrap();

// create a nameserver for a response
let ns = Nameserver::response_obj()
  .ldh_name("ns1.example.com")
  .entity(holder.clone())
  .extension(ExtensionId::IcannRdapResponseProfile1.as_ref())
  .extension(ExtensionId::IcannRdapTechnicalImplementationGuide1.as_ref())
  .notice(Notice::builder().title("Inaccuracy resport").build())
  .build()
  .unwrap();

// create an autnum for a response
let autnum = Autnum::response_obj()
  .autnum_range(700..700)
  .entity(holder)
  .extension(ExtensionId::NroRdapProfile0.as_ref())
  .notice(Notice::builder().title("test").build())
  .build();

RDAP uses jCard, the JSON version of vCard, to model "contact information" (e.g. postal addresses, phone numbers, etc...). Because jCard is difficult to use and there might be other contact models standardized by the IETF, this library includes the [contact::Contact] struct. This struct can be converted to and from jCard/vCard with the [contact::Contact::from_vcard] and [contact::Contact::to_vcard] functions.

[contact::Contact] structs can be built using the builder.

use icann_rdap_common::contact::Contact;

let contact = Contact::builder()
  .kind("individual")
  .full_name("Bob Smurd")
  .build();

Once built, a Contact struct can be converted to an array of [serde_json::Value]'s, which can be used with serde to serialize to JSON.

use icann_rdap_common::contact::Contact;
use serde::Serialize;
use serde_json::Value;

let contact = Contact::builder()
  .kind("individual")
  .full_name("Bob Smurd")
  .build();

let v = contact.to_vcard();
let json = serde_json::to_string(&v);

To deserialize, use the from_vcard function.

use icann_rdap_common::contact::Contact;
use serde::Deserialize;
use serde_json::Value;

let json = r#"
[
  "vcard",
  [
    ["version", {}, "text", "4.0"],
    ["fn", {}, "text", "Joe User"],
    ["kind", {}, "text", "individual"],
    ["org", {
      "type":"work"
    }, "text", "Example"],
    ["title", {}, "text", "Research Scientist"],
    ["role", {}, "text", "Project Lead"],
    ["adr",
      { "type":"work" },
      "text",
      [
        "",
        "Suite 1234",
        "4321 Rue Somewhere",
        "Quebec",
        "QC",
        "G1V 2M2",
        "Canada"
      ]
    ],
    ["tel",
      { "type":["work", "voice"], "pref":"1" },
      "uri", "tel:+1-555-555-1234;ext=102"
    ],
    ["email",
      { "type":"work" },
      "text", "joe.user@example.com"
    ]
  ]
]"#;

let data: Vec<Value> = serde_json::from_str(json).unwrap();
let contact = Contact::from_vcard(&data);
