摘　　要：PROV是关于数据溯源的一系列规范,与DC元数据存在密切的联系。在数字图书馆领域,数据溯源成为一种趋势,如何利用DC元数据建立数据溯源体系就成为研究重点之一。本文从DC元数据和PROV概念入手,比较分析其关系,探讨两者之间的映射,得出若要满足数据溯源要求,DC元数据需增加描述活动、关系、代理相关字段的结论。PROV is a series of standard about data provenance, which is closely related with the DC metadata. In the field of digital library, the traceability data become a kind of trend, and how to use DC metadata to establish data provenance system has become one of the key research. This paper starts with the concept of DC metadata and PROV, compares and analyses the relationship between them, and discusses the mapping between them. It comes to a conclusion that if we want to meet the data provenance requirement, DC needs to add the description about activity, relationship and agent.
