          JSContact: A JSON representation of addressbook data
                      draft-stepanek-jscontact-03

Abstract

   This specification defines a data model and JSON representation of
   contact card information that can be used for data storage and
   exchange in address book or directory applications.  It aims to be an
   alternative to the vCard data format and to be unambiguous,
   extendable and simple to process.  In contrast to the JSON-based
   jCard format, it is not a direct mapping from the vCard data model
   and expands semantics where appropriate.

1.  Introduction

   This document defines a data model for contact card data normally
   used in address book or directory applications and services.  It aims
   to be an alternative to the vCard data format [RFC6350] and to
   provide a JSON-based standard representation of contact card data.

   The key design considerations for this data model are as follows:

   o  Most of the initial set of attributes should be taken from the
      vCard data format [RFC6350] and extensions ([RFC6473], [RFC6474],
      [RFC6715], [RFC6869], [RFC8605]).  The specification should add
      new attributes or value types, or not support existing ones, where
      appropriate.  Conversion between the data formats need not fully
      preserve semantic meaning.

   o  The attributes of the cards data represented must be described as
      a simple key-value pair, reducing complexity of its
      representation.

   o  The data model should avoid all ambiguities and make it difficult
      to make mistakes during implementation.

   o  Extensions, such as new properties and components, MUST NOT lead
      to requiring an update to this document.

   The representation of this data model is defined in the I-JSON format
   [RFC7493], which is a strict subset of the JavaScript Object Notation
   (JSON) Data Interchange Format [RFC8259].  Using JSON is mostly a
