摘要/Abstract

摘要： 为了保持用户数据库现势性，需将数据库更新过程中产生的增量信息及时发布给用户。而增量信息的建模与描述是实现发布的前提。以中国1∶25万地形数据库的两个版本为例研究了增量信息的数据建模和数据描述的问题。提出了基于超图数据模型的建模和基于资源描述框架（RDF）的增量信息描述方法。该方法能够以统一的方式实现不同增量信息的建模和描述，具可行性和有效性。

Abstract: For keeping reality of user’s database, the incremental information created by updating need to be given to users in time. However, the modeling and its description are realized preconditions. Taking two versions of the topographic database with scale 1∶250 000 in China as an example, the questions were studied on data modeling and its description. The author put forward the modeling method based on hypergraph data model (HDM) and its description on the basis of RDF （resource description framework）. It can realize the modeling and description for different incremental information using a uniform style, with feasibility and validity.

Key words: topographic database, incremental information, hypergraph data model, modeling, RDF
