| 摘 要： | FRBR的实体-关系模型是RDA编制的结构基础,这种概念完全不同于AACR2的理念,同时它也是理解RDA的难点论文主要针对RDA中的实体、实体中的元素、实体之间的关系进行了分析,并利用图表进行详细的说明.结论是：RDA对文献描述的四个层次包括作品、内容表达、具体表现、单件,可以对书目信息进行深度揭示,四个层次之间也存在比较复杂的关系.

| Abstract: | The FRBR entity-relationship model is the infrastructure of RDA. This concept is completely different from the concept of AACR2, and it is difficult to understand. The RDA entities, the entity elements and the relationship between enti- ties are analyzed and illustrated by charts in this paper. The conclusion is that RDA can reveal the document information in four levels, including the work, expression, manifestation, item, which can reveal the bibliographic information in the depth. There is a complicated relationship between the four levels. |
