Cosmo is the OSAF calendar sharing server. With your favorite calendar program (Chandler, Apple iCal, Mozilla Sunbird, or any other WebDAV or CalDAV enabled client), you can share your calendar with other people by publishing it to Cosmo. Your shared calendars can be subscribed to and updated by anyone, even if they don't have an account on your server. Cosmo provides Atom feeds for shared calendars, so you can track updates in your favorite feed reader and integrate your calendar into your Web site or blog.
The Privilege Separation patches for Apache HTTPD and 'mod_dav' address the problem that an Apache WebDAV server can only write files as the non-privileged Web server user (usually something like 'nobody' or 'www'). The patches address this shortcoming in a secure way by adding privilege separation to the Apache Web server (conceptually similar to SSH privilege separation). A privilege-separated Apache can be used to provide secure WebDAV write access to ~user directories and allow the use of per-user Unix quotas. When combined with mod_ssl, it provides a convenient and secure remote file serving system, as WebDAV clients are seamlessly integrated into both Windows and Mac OS X.
mod_athena is an Apache-based application load balancer for large systems. It allows the HTTP server to act as a load balancer either internally to Apache's own mod_proxy (for reverse proxying), or externally to machines querying it. Arbitrary statistics are sent to the engine via a simple GET plus query-string interface, from which it will then make decisions based on chosen algorithms.
RIFE/Laszlo is based on RIFE/Jumpstart and geared towards easily getting started with the creation of Rich Internet Applications using OpenLaszlo. It is a ready-to-run source distribution and file structure that allows you to get started with a new OpenLaszlo application with RIFE in less then 2 minutes. Typically, all that you have to do is unzip the archive, open the project file in your favourite IDE, and run the application. Thanks to a dynamic development model, you rarely have to restart, and are able to gradually implement your application in an iterative manner.
Extended Virtual Synchrony for Java is a pure Java implementation of the totem single-ring protocol, which provides process group membership and reliable multicast with totally ordered messages. Because of its token-based design, this protocol is unique in achieving effective flow control, and is ideal for implementing replication in small clusters.
Graffito is a framework used to build content-based applications like CMSs, document management systems, forums, blogs, etc. It offers a complete platform for creating, managing, and publishing content in your portal or in any other kind of Java application. It integrates content repositories, workflow, collaboration, and personalization via existing open source projects and standards like WEBDAV.
x4juli is a port of the main parts of log4j to the J2SE Logging API. The default implementation is incomplete and therefore still not widely used, even when introduced in J2SE 1.4. x4juli provides logmanagers, formatters, handlers, and filters to fill the gap. The interface and use of the original API has not been changed. Additionally, x4juli delivers a native implementation of the Jakarta Commons Logging (JCL) API and the Simple Logging Facade for Java (SLF4J) API.
Jetspeed-2 is a full implementation of the Java Portlet API. It is fully compliant with the Portlet Specification 1.0 (JSR-168). It has passed the TCK (Test Compatibility Kit) suite and is fully CERTIFIED to the Java Portlet Standard. Notable features include security components backed by LDAP and database implementations, and some robust administration interfaces. Custom portals can be built and deployed using the Jetspeed plugin for Maven. Developers can use the Jetspeed PSML language to assemble portlets, and the Apache Portals Bridges project to 'bridge' portals with existing technologies including Struts, JSF, PHP, and Perl. For GUI designers, Jetspeed comes with several built-in templates used to decorate portals and portlets.
Nexenta is a complete GNU-based operating system built on top of the OpenSolaris kernel and runtime. The Debian system is used for software distribution and packaging to glue the numerous pieces together. However, Nexenta is not currently part of the Debian Project, nor are its packages present in the Debian database. It includes Apache, MySQL, Perl, Python, PHP, Firefox, Evolution, a software update manager, Synaptic package manager, Gaim, Abiword, administration and development utilities, editors, graphics, GNOME, interpreters, libraries, and much more.
Isobel is a framework to build complex information retrieval and analysis systems. Isobel can be functionally divided in two subsytems, Isobel Gatherer (the crawling and filtering subsystem) and Isobel Analyzer (the analysis subsystem). The two subsytems can also be used separately. Isobel Gatherer offers ready-to-use services like content fetching, scheduling, document format conversion, Hyperlink graph storage and analysis, content storage and indexing. A programmer may easily add new services. Isobel Analyzer uses the IBM UIMA architecture to reuse the analysis components developed for this architecture.
