It's important to construct 3D model database to prevent repeated resource construction and information Island, and the unified metadata standard is the basis and essential prerequisite of model database construction. Firstly, the model metadata framework which is represented by 2D matrix is designed through comparing the home and abroad metadata standards in this paper. Secondly, the 3D model's metadata will be constructed through the combination of manual metadata marking and automatic metadata extraction. Finally, a shared service system is developed to verify that this approach can fully demonstrate the characteristics of 3D model and improve the retrieval efficiency.
