Bespin proposes an open extensible web-based framework for code editing... empowering Web developers to hack on the editor itself and make it their own.

What Jangle (Just another generic library environment) is an experiment with middleware for library applications. If you build, use, manage or just want simple access to a library system, Jangle could be for you. Why The aim of the Jangle project is to provide a free, easy to use framework for building web services for LMSs/ILSs by exposing resources through the Atom Publishing Protocol. The goal of Jangle is to develop conventions intercommunication between the backend library services, such as ILSes and other applications and the AtomPub server (known as the Jangle "core"). By leveraging AtomPub, it eliminates the need to develop an entirely new API and allows developers to use existing client library and knowledge to easily integrate library data into new places.

Joomla is an award-winning content management system (CMS), which enables you to build Web sites and powerful online applications. Many aspects, including its ease-of-use and extensibility, have made Joomla the most popular Web site software available. Best of all, Joomla is an open source solution that is freely available to everyone.

HUBzero allows you to create dynamic web sites that connect a community in scientific research and educational activities. HUBzero sites combine powerful Web 2.0 concepts with a middleware that provides instant access to interactive simulation tools. These tools are not just Java applets, but real research codes that can access TeraGrid, the Open Science Grid, and other national Grid computing resources for extra cycles. HUBzero was created by researchers at Purdue University in conjunction with the NSF-sponsored Network for Computational Nanotechnology. The technology was originally developed to support nanoHUB.org, a national resource for nanotechnology simulation. It has since been extended to create science gateways for other scientific domains.

WS-* specs

There are a variety of specifications associated with web services. These specifications are in varying degrees of maturity and are maintained or supported by various standards bodies and entities. Specifications may complement, overlap, and compete with each other. Web service specifications are occasionally referred to collectively as "WS-*", though there is not a single managed set of specifications that this consistently refers to, nor a recognized owning body across them all. The reference term "WS-*" is more of a general nod to the fact that many specifications are named with "WS-" as their prefix. This page includes many of the specifications that might be considered a part of "WS-*".

RSF is an open source web programming framework, with roughly the scope of Sun's JSF. RSF is written in Java, and is built on the Spring framework. RSF features a pure-HTML templating engine named IKAT, which achieves the cleanest separation between presentation and logic yet made - build "components" using pure HTML and libraries of code rather than heavy framework base classes. RSF also features a lightweight request-scope Spring clone, RSAC, which brings the magic benefits of inversion of control into the request scope. RSF currently has integrations for Hibernate, JSR-168, Cocoon and Sakai

This could be a good model for us since it is a very very clean separation of logic from layout. Makes widgets available to <div> containers in XHTML.

Shale is a modern web application framework, fundamentally based on JavaServer Faces. Architecturally, Shale is a set of loosely coupled services that can be combined as needed to meet particular application requirements. Shale provides additional functionality such as application event callbacks, dialogs with conversation-scoped state, a view technology called Clay, annotation-based functionality to reduce configuration requirements and support for remoting. Shale also provides integration links for other frameworks, to ease development when combinations of technologies are required.
