摘　　要：几乎所有的事物都具有时态特征,时态信息处理在电子商务、数据挖掘、时空和多媒体信息技术以及网络应用等方面发挥着越来越重要的作用。另一方面,由于当前互联网缺乏智能性,大多数搜索工作都要靠人工进行,对人们的生活与工作造成极大不便,因此语义网受到了一定的关注。而资源描述框架(RDF)这一用于描述网络中元数据的语言,也是实现语义网的基础,其存储问题也逐渐成为研究热点。随着越来越多时态RDF格式的数据涌入互联网,合理存储和管理时态RDF数据也成为亟待解决的问题之一。文中在传统RDF存储、时态RDF模型以及时态数据库研究的基础之上,设计了一个时态RDF数据存储系统TRDF-STORAGE,就该系统的结构层次中每一个模块的原理及细节进行了详细的描述,并进行了简单的系统展示。Almost everything has temporal characteristics.Temporal information processing is playing an increasingly important role in e-commerce,data mining,space-time,multimedia information technology and network applications.On the other hand,due to lack of intelligence in the Internet at present,most of the search work have to be done manually,which has caused great inconvenience to the people’s life and work.Therefore,the semantic web has received some attention.The resource description framework(RDF)is a language for describing the meta data in the network and also the basis of realizing the semantic web,and its storage problem has gradually become a research hotspot.As more and more temporal RDF format data influx into the Internet,the rational storage and management of temporal RDF data has become one of the problems to be solved.For this,we design a temporal RDF data storage system(TRDF-STORAGE),and give details of each module structure of the system based on the traditional RDF storage,temporal RDF model and temporal database research.
