摘要： 根据行星数据系统(PDS)标准规范、行星数据特点及PDS元数据模型，设计一个行星数据编目模型。通过扩展传统数据编目模型支持数据展示和空间查询，采用对象-关系数据库的方式存储编目信息以实现数据的管理、归档和分发。通过建立行星数据编目检索系统验证该模型的正确性和有效性，并表明该模型能提供一致的目录访问接口，使用户方便快速地检索到感兴趣的行星数据。

Abstract: According to the standard specification, planetary data characteristics of Planetary Data System(PDS) and PDS metadata model, this paper designs a planetary data cataloging model. By extending traditional data cataloging model to support data show and space inquires, using the method of object-relational database to store cataloging information to realize data management, filing and distribution. The planetary data cataloging index system validates the correctness and effectiveness of the model, and shows that this model can provide a consistent directory access interface, makes the user quickly and easily to retrieve the interested planet data.
