基于元数据的交通运输科学数据共享平台设计

Design of Metadata-based Traffic Scientific Data Sharing Platform

为了整合交通运输行业分散的数据资源,改善网络科学数据组织的状况,提高对资源的存取和利用效率,文章从元数据的涵义、标准入手,介绍了交通运输科学数据共享元数据内容,提出了交通运输科学数据资源体系框架,并设计构建了基于元数据的交通运输科学数据共享平台。实践表明,元数据模式非常适于网络环境下交通科学数据资源共享,同时也指出平台实际运行中存在的问题及进一步的研究方向。

The goal of this paper is to integrate the transport sector distributed data resources, to improve the organization of scientific data network conditions, and to improve access and resource use efficiency. First, the meaning and standard of the metadata were explained. Metadata content of transportation science data were introduced, Then, the framework of the scientific data transport resources system was introduced. Furthermore, a metadata-based traffic scientific data sharing platform was designed. Practice shows that metadata model is very suitable for traffic scientific data sharing resources under network environment. Meanwhile, the actual problems and further development of the platform were also pointed out.
