Method and system for metadata organization and management based on metadata graph

Abstract

The invention discloses a metadata graph-based metadata organization management method and system. The method is implemented by comprising the steps of storing a file to obtain file metadata, extracting semantic information of the file, and constructing semantic metadata by utilizing the semantic information; and by utilizing a semantic relationship between the file metadata and the semantic metadata, constructing a metadata graph; and by utilizing the metadata graph, performing metadata organization management, and providing an intelligent service. According to the method, the metadata graph is constructed; metadata organization management is performed by utilizing rich file metadata and semantic information of the metadata graph; and the intelligent service is provided. The method is high in efficiency of performing metadata organization management by utilizing the metadata graph, rich in function, strong in expansibility and high in intelligent level, and can perform data mining and analysis and realize the intelligent service.

Description

technical field [0001] The invention belongs to the field of computer data storage, and more particularly relates to a method and system for organizing and managing metadata based on a metadata graph. Background technique [0002] The continuous growth of data scale has brought huge challenges to traditional storage systems. At present, most storage systems adopt the method of separating control flow and data flow, and use independent metadata servers or clusters to provide metadata services. Although metadata only accounts for 0.1% to 1% of the entire data space, 50% to 80% of the accesses in the file system are for metadata, so it can be seen that the management of metadata is very important. [0003] At present, most metadata servers use a tree-structured namespace to organize and manage file metadata. This method requires users to organize their files under precise paths according to the hierarchical relationship between files and directories. Others use relational data...
