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.
