File services method based on ContextFS context file systems

Abstract

The invention discloses a file servicing method based on ContextFS context file system, which comprises the following steps: utilizing each kind of portable calculating equipment and sensor in the space or user to acquire the context information in the space for user; affirming the ID; affirming the preference context of user according to the historic operation or historic data of self-defined preference; constructing virtual catalog and virtual file according to the file element data and context information in the file system; recording the user and context information by file system to store and transmit to the context file system when the user accesses the virtual catalog and virtual file. The invention is characterized by positive service, which reorganizes to generate virtual catalog and virtual file.

Description

technical field [0001] The invention relates to the field of file systems, and mainly relates to a file service method based on the ContextFS context file system. Background technique [0002] With the development of pervasive computing and the maturity of next-generation storage technology, a large amount of information is stored in various file systems in the form of files. Traditional file systems and other distributed file storage systems use a simple directory structure to organize files. , the directory name is only used as a means to resolve namespace conflicts, and the complex and cumbersome file classification and retrieval work is passed on to the user; on the other hand, the file metadata supported by the traditional file system is scarce, often only including the creation time Simple metadata such as , modification time, owner, read and write permissions, etc., these metadata cannot provide help for content-based file classification and retrieval; further, the me...

[0002] With the development of pervasive computing and the maturity of next-generation storage technology, a large amount of information is stored in various file systems in the form of files. Traditional file systems and other distributed file storage systems use a simple directory structure to organize files. , the directory name is only used as a means to resolve namespace conflicts, and the complex and cumbersome file classification and retrieval work is passed on to the user; on the other hand, the file metadata supported by the traditional file system is scarce, often only including the creation time Simple metadata such as , modification time, owner, read and write permissions, etc., these metadata cannot provide help for content-based file classification and retrieval; further, the method of controlling permissions with a single file as the smallest unit is inflexible, and Multiple storage of different fragments of the same content file results in a large waste of storage resources
