WCAP meaning in Networking ?

Web Calendar Access Protocol (WCAP) is a protocol for remote client-server calendar access and scheduling based on the XML, HTTP, iCalendar, and vCard Internet standards. WCAP was created for use with the product that eventually became Sun Java System Calendar Server, but is also used by the open source Buni Meldware project. WCAP uses simple HTTP GET commands for accessing iCalendar, Freebusy, TODO and vCard entries. WCAP responses are either the traditional text form or an XML form of iCalendar/etc. Several plugins exist including those for Mozilla Thunderbird, Novell Evolution and Microsoft Outlook. There is a competing protocol called CalDAV undergoing standardization.
