RDA=Resources Description and Access
RDA的目的：The data created using RDA to describe a resources are designed to assist user performing the following task: find,identify ,select, obtain。這個最終報告是在1998年根據Authority Data所完成的。
實際上，RDA是一個框架（framework),所以必須要分欄。而且RDA是不能單獨存在所以它會配合這些標準使用：AACR2,ISBD,MARC21 format for Authority Data,MARC21 for bibliographic data.
而ACCR2有5個格式：
1.MARC21 Format for Bibliographic Data
2. MARC21 Format for Authority
Data
3. MARC21 Format for Holdings
Data
4. MARC21 Format for
Classification Data
5. MARC21 Format for
Community Information
RDA需要滿足讀者的find，identify , select ,obtain，這是根據bibliography record同Authority Data所得出的要點。概念模式：
