Reusable Dialog Component (RDC) for voice application

A Reusable Dialog Component (RDC) is basically a JSP 2.0 tag, which generates VoiceXML at runtime. RDCs are part of the RDC Tag Library open source Jakarta project. Version 1.0 of the RDC Taglib was released in July 2005. The RDC Taglib projects implifies the development of server-side code in order to generate Voice XML. The RDC Taglib project includes a set of RDCs, which are a collection of JSP 2.0 tags that assist in the development of Voice applications. The RDC tags generate VoiceXML at runtime, which can execute on any VoiceXML 2.0 compliant platform. The RDC Taglib also provides a framework for implementing additional RDCs. The framework helps in orchestrating each individual RDC making sure the user data is collected, verified, and canonicalized. The collection of RDCs included in the Taglib project is made up of both, atomic and composite RDCs. Atomic RDCs collect a single piece of information from the user. For example, date, time, or zipCode are atomic RDCs. Composite RDCs collect multiple pieces of information from a user. These are usually done by using atomic RDCs or aggregating a composite with other atomic RDCs.
