Component Specification and Wrapper/Glue Code Generation with Two-Level Grammar Using Domain Specific Knowledge

UniFrame is a framework for seamlessly assembling heterogeneous distributed components. It’s based on the Unified Meta-component Model (UMM) for describing components. Systems constructed by component composition should meet both functional and non-functional requirements such as the Quality of Service (QoS). We propose a Component Description Language (CDL) to specify the UMM components based on domain specific knowledge in the context of UniFrame using Two-Level Grammar (TLG). CDL is also used for wrapper/glue code generation. A simple case study is illustrated to show how CDL may be applied.
