Personal Data Interchange: vCalendar & vCard formats (RFC-based).
Personal Data Interchange (PDI) occurs every time two or more individuals communicate, in either a business or personal context, face-to-face, or across space and time. Such interchanges frequently include the exchange of informal information, such as business cards, telephone numbers, addresses, dates, and times of appointments. Augmenting PDI with electronics and telecommunications can help ensure that information is quickly and reliably communicated, stored, organized and easily located when needed.
The versit consortium developed a comprehensive family of PDI technologies based on open specifications and interoperability agreements to help meet this technology need and that will allow you to communicate more easily, faster and more accurately. The two main technologies that came from the versit consortium were vCard, an electronic business card, and vCalendar, an electronic calendaring and scheduling exchange format.
Beginning in December, 1996, the Internet Mail Consortium took on responsibility for the development and promotion of these two important technologies. The press release from the two organizations explains IMC’s new stewardship.
