The parametric feature-based modeling systems can express design intent at high-level. But they usually lack representations for explaining why the feature is selected, what its design purpose and source are. This paper integrates the design intent object with design rationale and proposes an ontology-based representation framework for design meta-intent information. An approach to ontology instantiation for design intent objects and meta-intent properties by semantic annotating is presented. In order to improve the annotating efficiency the methods to automatically capture the design meta-intent information are also discussed. Based on above approaches the design meat-intent information can be naturally and effectively constructed during design process.
