Abstract: This paper analyzes the features and demerits of traditional data modeling, imports a unified data model for knowledge to support uniform knowledge management and information integrating in the e-government domain. Based on the unified data model, it designs and implements a unified development environment for building knowledge management platform. The practice proves that building knowledge management platform based on the unified data model for knowledge makes the system manage all kinds of knowledge in a consistent way and adapt to application of new kinds of knowledge quickly.

Key words: knowledge management, unified data model, meta-data, meta-model
