元数据研究在医学数据资源共享中的作用

Metadata Study in Medical Data Resource Share

目的在医学数据资源共享中,通过对元数据的研究对异构医学数据资源进行检索与发现。方法研究元数据的定义与特征,制定元数据标准、然后建立目录服务系统进行数据检索服务。结果建立了基于元数据的目录服务体系,实现了数据发现服务。结论元数据方法的研究是对异构数据进行检索与发现的有效方法,也是实现医学数据资源共享的重要途径。

Objective To study the application of Metadata in search and find data with different structue in medical data resources share. Methods Study the definition and character of metadata, establish the metadata standard and directory service system to execute the data search service. Results The Directory Service System based on the method of rnetadata has been developed, in which the data search service can be realized.
