A framework for creating JSP taglibs that aid in rapid development of voice and multimodal applications.
Server-side generation of HTML has proven an effective way of generating the user interface for visual web applications. Over time, the effort involved in such HTML generation has been reduced by the availability of various JSP tag libraries that abstract away the minutiae of HTML markup. The RDC project aims to achieve for voice and multimodal applications what JSP tag libraries have already achieved in the world of visual web applications.

Cross-platform library easing many progamming tasks in C.
The mission of the Apache Portable Runtime (APR) project is to create and maintain software libraries that provide a predictable and consistent interface to underlying platform-specific implementations. The primary goal is to provide an API to which software developers may code and be assured of predictable if not identical behaviour regardless of the platform on which their software is built, relieving them of the need to code special-case conditions to work around or take advantage of platform-specific deficiencies or features.
