一种用嵌套哈希表和动态数组规范MARC数据的方法

A Data Structure for Normalizing MARC by Using Nested Hashtable and Dynamic Array

通过对比当前ISO2709格式MARC数据的常规处理方法,提出一种使用嵌套哈希表及动态数组来存储MARC数据的数据结构,并根据此数据结构进行排序及去空字段等操作,简化程序复杂度。

This paper compares some usual methods of processing MARC in IS02709, and gives a new data structure of nested hashtable and dynamic array to normalize MARC. The author shows how to sort the MARC data according to this data structure and delete empty fields.
