【Abstract】 In order to improve component comprehension and reuse, this paper describes an component reuse process model, based on which a self descriptive component interface model SDI was proposed. SDI is extensible, defines component interface specification from two dimensions: reuse process and view, provides information and constraints for component implementation to support reuse in different development phases, and supports the understanding, analysis and prediction of component semantic and effective boundary. The implementation of SDI proves that it is beneficial for component understanding, and can promote reuse efficiency effectively.更多还原
