                    jCard: The JSON Format for vCard

Abstract

   This specification defines "jCard", a JSON format for vCard data.
   The vCard data format is a text format for representing and
   exchanging information about individuals and other entities, for
   example, telephone numbers, email addresses, structured names, and
   delivery addresses.  JSON is a lightweight, text-based, language-
   independent data interchange format commonly used in Internet
   applications.
