VXIinet, VXIcache, and VXIjsi interfaces

VXIinet	Internet Interface
OSBinet	OSBinet implementation of VXIinet
VXIcache	Cache Interface
VXIjsi	ECMAScript (JavaScript) Engine Interface
OSBjsi	OSBjsi implementation of VXIjsi

The OpenVXI requires a number of basic foundational components to functions including: Internet I/O, caching, and ECMAScript execution. These services are provided by the VXIinet, VXIcache, and VXIjsi interfaces respectively.

The OpenVXI implements the VXIinet interface using the W3C Libwww open source Internet library. This implementation provides for document and prompt access through http:// and local files, as well as the ability to submit (POST) information via http://.

The OpenVXI does not currently implement the VXIcache interface, as this interface is not currently used by the VXI. However, a future release of the OpenVXI will use this interface to cache the XML DOM for parsed VoiceXML pages in order to increase performance. This component would typically be used by a real VXIrec implementation for caching compiled grammars as well.

The OpenVXI implements the VXIjsi interface using the Mozilla SpiderMonkey open source ECMAScript (JavaScript) library. This implementation allows manipulating ECMAScript variables as well as executing arbitrary ECMAScript blocks.
