Embodiment Construction

[0040] The technical solutions of the present invention will be described in detail below in conjunction with the drawings and specific examples to further illustrate the purpose, solutions and effects of the present invention. The provided drawings and examples are not intended to limit the protection scope of the claims of the present invention.

[0041] The basic idea of ​​realizing the synchronization of distributed geoscience metadata in the present invention is: use network service technology to encapsulate geoscience metadata operation functions to form geoscience metadata synchronization services, and deploy geoscience metadata synchronization services in the main center and sub-centers respectively . The real-time synchronization of sub-center metadata between the sub-center and the main center is realized through the geoscience metadata synchronization service. The specific implementation is divided into two processes: the deployment of geoscience metadata synchroniz...

Abstract

The invention discloses a method and a system for realizing the synchronization of distributed earth science metadata, comprising an earth science metadata synchronization server deployment step and an earth science metadata synchronization implementation step, wherein the earth science metadata synchronization server deployment step is used for encapsulating an earth science metadata operation function into an earth science metadata synchronization service and deploying the earth science metadata synchronization service on network servers of a general center and a branch center; and the earth science metadata synchronization implementation step carries out the earth science metadata synchronization of the general center and the branch center on the basis of the earth science metadata synchronization service. The invention solves the problems of the real-time propelling movement and the synchronization of the earth science metadata under a distributed software system.

Description

technical field [0001] The invention relates to geoscience metadata synchronization technology, in particular to a distributed geoscience metadata synchronization implementation method and system. Background technique [0002] Through the long-term investigation and monitoring of the earth's surface and depth deployed by various industries and various geoscience research projects, my country has accumulated rich geoscience data resources. Especially with the development of earth observation technology in recent decades, the acquisition of geoscience data resources has become easier and easier. However, due to the lack of effective geoscience data sharing, data resources are difficult to circulate. Data resources distributed in different geographical locations, industry departments and scientific research units are mainly used in data collection and production units, and industry departments and scientific research projects are often used for different purposes. Repeat inves...
