 Universal private address with XRI and I-Names



The vCard standard defines a format for electronic business cards intended for Personal Data Interchange (PDI), i.e. exchanging personal information between individuals. The current version 3.0 of the vCard specification, which has been developed by the Internet Mail Consortium, is defined in RFCs 2425 and 2426. The vCard specification is operating system independent; all information is stored in a file (usually recognisable by its extension “.vcf”) that is mainly text-based. VCards are supported by and used in various applications and contexts, such as Web browsers, email clients and Personal Information Managers. 

A vCard may contain the following types of information: 

  1. Personal information, such as identification information (the name, nickname, and birthday of a person), addressing information (a person’s home, business and email addresses, various telephone numbers), and organisational information (the organisation a person is associated with, his title and role within the organisation). 

  2. Additional geographic information which may be useful when contacting the respective person, such as the time zone or geographical co-ordinates of the address where the person can usually be reached. This is usually static and does not indicate a person’s current location. 

  3. Additional multimedia information, such as a photography of the person or a sound file containing the correct pronunciation of the person’s name. 

Table 1 shows an example of a vCard containing only text-based elements.
