SERVICES OF MARINE GEOLOGY DATA RESOURCE DIRECTORY BASED ON REST AND ODATA

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.
