OpenGroupware.Org Groupware Server & Collaberation Platform
OpenGroupware.Org is a full-featured groupware server and collaboration platform. OpenGroupware (commonly known as "OGo") runs as a daemon, developed in Objective-C, and ties into Apache via a module. Support for GroupDAV, WebDAV, and CalDAV is provided by the ZideStore service, as well as an XML-RPC API known as "zOGI" (ZideStore OpenGroupware Interface). Applications include contact management, project and document managment, tasks, and sophisticated scheduling. The schedular supports conflict detection, resource allocation, and multiple time-zones.
