A JSON Binding and Encoding for TeRI
draft-peterson-modern-teri-json-00.txt
Abstract
The Telephone-Related Information (TeRI) framework defines an
information model for data objects related to the acquisiton,
management, and retrieval of telephone numbers and information
related to them via the Internet. TeRI provides an abstract
framework that must be instantiated by a particular binding and
encoding. This document defines an HTTP binding for TeRI and a
JavaScript Object Notation (JSON) encoding for TeRI.

1. Introduction
The Telephone-Related Information (TeRI) framework
[I-D.peterson-modern-teri] defines an information model for data
objects related to the acquisiton, management, and retrieval of
telephone numbers and information related to them via the Internet.
TeRI provides an abstract framework that must be instantiated by a
particular binding and encoding, as described in
[I-D.peterson-modern-teri] Section 6.2 and 6.3, respectively. This
document defines an HTTP binding and JavaScript Object Notation
(JSON) [RFC7159] encoding for TeRI. It does not however define any
particular profile or deployment environment for using TeRI in this
fashion; this only demonstrates an instantiation of the baseline TeRI
specification using JSON.
This is an early stage Internet-Draft that serves primarily as a
vehicle to give examples of a potential syntax for TeRI Requests and
Responses in order to facilitate discussion.
2. Terminology
In this document, the key words "MAY", "MUST, "MUST NOT", "SHOULD",
and "SHOULD NOT", are to be interpreted as described in [RFC2119].
This document also incorporates the terminology of the MODERN
Framework [I-D.ietf-modern-problem-framework].

3. HTTP TeRI Binding
This specification defines a RESTful interface for getting and
putting JSON objects related to TeRI at a web service.
TBD.
4. JSON TeRI Encoding
This specification defines separate JSON objects to carry TeRI
Requests and Responses. All JSON objects begin with a "TeRI"
element, which has a value stating whether the object contains a
Request or a Response.
4.1. TeRI Requests
Per TeRI [I-D.peterson-modern-teri], all requests will have a Source
and a Subject. Optionally, a block of Attributes will also appear in
the Request.
This simplest TeRI request will therefore have the following form:
{ "TeRI":"Request",
"Source":{"Request":"example.com"},
"Subject":{"T":"12125551111"} }
A Request may have two types of Sources: a "Request" Source or an
"Intermediary" Source. The "Source" element is given as an array
here because a Request may have multiple Sources, including one
"Request" Source and one or more "Intermediary" Sources. All
Requests have a single Subject. The encoding of a Subject follows
the Service Types given in [I-D.peterson-modern-teri] Section 4.2.1.
Here, Type "T" signifies a single telephone number.
Most of the complexity in Requests comes from Attributes. Attributes
appear in their own JSON array. An Attribute typically serves to
qualify a request. In this example, the TeRI request is only asking
for an Internet-based SMS service (see [I-D.peterson-modern-teri]
Section 5.5.2) associated with the telephone number "12125551000".
{ "TeRI":"Request",
"Source":{"Request":"example.com"},
"Subject":{T":"12125551000" } ,
"Attribute":{
"Service":"sms"}
}

4.2. TeRI Responses
All TeRI responses will give a Response Code. The simplest TeRI
responses are therefore simple failure responses.
{ "TeRI":"Response",
"Code":"Unauthorized Source" }
[TBD: Note that TeRI has not allocate Response Codes yet; these will
accompany the human-readable response indicators like "Unauthorized
Source"]
Most interesting TeRI responses contain Records, which are specified
in Section 4.3.
4.3. TeRI Records
A TeRI Record consists of a JSON array containing a set of elements
as defined in [I-D.peterson-modern-teri]. Records may appear in both
TeRI Requests and Responses; for Retrieval Operations, it would be
most common for Records to appear in Responses, when the Request
indicates a Subject that the Source would like receive Records
related to.
{ "TeRI":"Response",
"Code":"Success",
"Record:{
"Identifier":"dc9a25c5-e44a-4dc1-9ff7-609da04bd694",
"Authority":{"x5u":"http://example.com/cert.cert"},
"Contact":"admin@example.com",
"Service":{"U":"sip:alice@example.com"},
"Signature":"dBjftJeZ4CVP-mB92K27uhbUJU1p1r_wW1gFWFOEjXk" }
}
This is a simple example of a Record; more complex records may
contain Priorities or Expiries. Note that the Service Type here
follows the [I-D.peterson-modern-teri] Section 4.2.1 Types, as did
the Attributes in the Request above.
