Abstract

The invention provides a data harvesting method and device for decentralization of a scientific data sharing platform, and the device comprises a plurality of server nodes, any server node can be used as a data provider or a data harvesting party, and can be used as the data provider to publish metadata to a local data storage device based on an OAI protocol. The secure access of the metadata is controlled through the access control device; metadata may be retrieved from other data provider storage devices using the reaping device as a data reaping party. According to the invention, the server nodes execute management of the data access control authority through the access control device, decentralization of the data harvesting process among the server nodes is realized, the data acquisition efficiency is improved, and meanwhile, the data access is safer.

Description

technical field [0001] The invention relates to the technical field of data resource transmission between nodes, in particular to a decentralized data harvesting method and device for a scientific data sharing platform. Background technique [0002] Metadata harvesting can be realized through data interaction between two server nodes, and the harvester can use the obtained metadata to provide retrieval and access. [0003] The term "data harvesting" here refers to the distributed data resource library on the Internet, obtaining metadata into this data resource library, and users can conduct unified searches in this data resource library and access data sources. [0004] The term "server" here refers to a data storage unit for storing data and metadata, and the data provider and data harvester described in this application are computing units that process data harvesting transactions. [0005] In the open data harvesting system, the data harvester sends a data harvesting req...
