WSDL and CORBA IDL

WSDL과 CORBA IDL

CORBA has been a popular middleware, but recently Web Services has been emerging as a promising web middleware since it uses Internet established standards such as URL, HTTP, XML, and etc. CORBA uses IDL for describing CORBA object interface and Web Services uses WSDL for its description. Thus, in order to port or integrate CORBA objects into Web Services, one needs to understand the relationship between CORBA IDL and WSDL. In this paper, we analyze IDL and WSDL, and compare between two. It turns out that there exists a direct mapping between two, and that understanding operational environments and logic of two technologies is much more important in converting or integrating CORBA objects into Web services successfully.
