Web Calendar Access Protocol

Web Calendar Access Protocol est un protocole client-serveur d'accès à distance aux calendriers et agendas basés sur les standards Internet XML, HTTP, iCalendar et vCard. WCAP a été créé pour être utilisé avec Sun Java Calendar Server, mais est aussi utilisé par le projet open source Buni Meldware[1]. WCAP utilise de simples commandes HTTP GET pour accéder aux données iCalendar, Freebusy, TODO et vCard. WCAP répond aussi bien sous forme de texte traditionnel ou sous forme de « xml » iCalendar/etc[2]. De nombreux plugins existent comme ceux pour Mozilla Thunderbird[3], Novell Evolution[4] et Microsoft Outlook[5]. Il existe un protocole concurrent nommé CalDAV en voie de standardisation.
