This paper describes LuaOrb, a binding between the extension language Lua and CORBA. Like other CORBA bindings, this binding allows a program to manipulate CORBA objetcts in the same way it manipulates local objects. Unlike conventional bindings, however, LuaOrb is based on the CORBA Dynamic Invocation Interface, mapping its dynamic character to the dynamic type system of Lua. This binding brings together CORBA reuse facilities with the flexibility provided by an interpreted language, fulfilling the "command center" concept proposed by Siegel.
