IBM UDDI Registry is a UDDI-compliant registry for Web services in a private intranet environment. (UDDI stands for Universal Description, Discovery, and Integration). Web services developers can publish and test their applications in a secure, private environment for internal business applications. This registry is geared toward activities such as Web services development, testing, and deployment for internal business applications, and therefore it has different requirements and characteristics than public UDDI registries.
Web Services Invocation Framework (WSIF) is a tool that provides a standard API for invoking services described in Web Services Description Language (WSDL), no matter how or where the services are provided. The architecture allows new bindings to be added at run time. WSIF enables developers to interact with representations of Web services instead of working directly with the Simple Object Access Protocol (SOAP) APIs, which is the usual programming model. With WSIF, developers can work with the same programming model regardless of how the Web service is implemented and accessed.
