Apple - Mac OS X - Mac OS X Server v10.4 Tiger Preview
A new Weblog server in Tiger Server makes it easy to publish, distribute and syndicate web-based content. The Weblog server provides users with calendar-based navigation and customizable themes, is fully compatible with Safari RSS and enables posting entries using built-in web-based functionality or with weblog clients that support XML-RPC or the ATOM API. The Weblog Server, based on the popular open source project "Blojsom," works with Open Directory for user accounts and authentication.
