UnCommon Web is a Web application framework. UnCommon Web features a component based UI construction toolkit, template and programmatic dynamic HTML generation engines, and linear (also known as modal or continuation) page flow control. UnCommon Web can sit behind Apache or a pure Lisp Web server.
The PEAK library tries to achieve high performance in combining multi-threading with an efficient I/O event model. You can write event-based applications that use massive sockets I/O, timers, and signals. Its underlying I/O multiplexing engine supports kqueue(2) (FreeBSD, NetBSD, and Mac OS X), epoll(2) (Linux 2.6), and /dev/poll (Solaris). It provides support for optimized memory allocations, basic database primitives, and synchronization.
Morena is a Java framework that allows a Java program to acquire an image from a scanner or camera. To communicate with the hardware, it uses standard interfaces: Twain for MS Windows and Mac OS X and Sane for a number of Unix platforms (AIX, BeOS, Darwin, FreeBSD, HP-UX, Linux, NetBSD, OpenBSD, OS2, Solaris, Unixware).
Cut The Crap Software radically simplifies the task of java-based system development. Packages focussed on such problems as persistence, object model representation and XML processing contribute to the encompassing goal of viable model-based system generation from simple descriptions.
P::Classes is a portable, high performance C++ application framework which provides many classes needed for real-world application development, emphasing on ease of use, size and stability. Its current highlights are a typesafe and threadsafe signal/slot mechanism, an I/O system including a plugin-based architecture for network-protocol transparent I/O, a plugin-based application message logging framework, classes and driver-plugins to access SQL databases, a message digest library, and classes for configuration management.
The Fedora software is based on an architecture known as FEDORA (Flexible Extensible Digital Object and Repository Architecture). The software takes advantage of distributed (or local) Web services, and makes representations of objects (called disseminations) available via HTTP. It is particularly good at handling complex digital objects where source datastreams and behaviors are distributed. There are two binary distributions (server and client), and a source distribution (including all libraries and source code needed to build any distribution).
NUI is a GUI ToolKit intended to work with SGI's OpenGL API. It is similar in many ways to GTK+, Qt and even Win32, but with many enhancements in order to make it an easy and yet powerful tool for cross- platform GUI programming. It is currently developed on platforms supported by the NGL framework.
