Temporal is the essential characteristic of information. Not only data has the nature of temporal but also knowledge. With the development of database and information technology, temporal information plays a very important role in information systems, even is decisive to some systems (electronic government affair and decision support system based on the temporal policy knowledge). In this paper temporal index is adopted to realize the logical unified temporal data view and the seamless conjunction of non-temporal data and temporal data, and the unified temporal information model of temporal knowledge and temporal data has been established with temporal attribute.
