摘　　要：为解决对分布式海洋地质数据资源快速访问和有效融合问题,满足数据资源共享和未来构建大数据应用的需求,提出一种基于REST架构模式和OData开放数据协议的海洋地质数据资源目录服务方案。首先探讨了基于REST和OData设计海洋地质数据资源目录服务的基本原则、关键环节,然后分别从目录服务资源实体识别、资源标识、实体数据模型、资源操作等方面进行了详细阐述,最后以ASP.NET WebAPI框架为基础说明了实现要点。结果表明,基于REST和OData设计的数据资源目录服务,使得用户可以快速获取分布式海洋地质数据资源,适用于海洋地质数据资源的组织、标识、获取和服务,该成果对促进地质数据资源的共享融合具有一定借鉴意义。In order to make more rapid visit and efficient integration of distributed marine geology data resources to meet the demand of data sharing and large data application,a marine geological data resource catalog service directory based on REST and OData is proposed in this paper.First of all,we discussed the basic principles and key links of directory services,and then elaborated in details the aspects of resource entity identification,resource identification,entity data model and resource operation.Finally,the key points for implementation are explained based on ASP.NET WebAPI framework.The results show that the data resources directory services based on REST and OData,will enable users to a quick access to distributed data resources and is applicable to the organization,identification,acquisition and service of marine geological data resources.This achievement is of significance to the sharing and integration of geological data resources.
