ISO/IEC 19500-3:2012

Information technology — Object Management Group — Common Object Request Broker Architecture (CORBA) — Part 3: Components

ISO/IEC 19500-3:2012 defines the syntax and semantics of a component model, based on CORBA IDL, and a corresponding meta-model, a language to describe the structure and state of component implementations, and a corresponding meta-model, a programming model for constructing component implementations, a runtime environment for component implementations, interaction between components and Enterprise Java Beans, meta-data for describing component-based applications, and interfaces for their deployment, and a lightweight subset of the component model, programming model and runtime environment.
