Problems solved by technology

[0005] The traditional way of file organization leads to weak self-description of files. At present, these technologies store file metadata on the file system, or it is limited to a specific format, which cannot be managed uniformly, or manually added on the basis of the traditional file system. Semantic structure, which does not have self-describing structural characteristics and metadata is separated from file content, depends on specific applications such as databases

Embodiment Construction

[0034] From the user's point of view, the file information concerned is, on the one hand, the content of the file itself, and on the other hand, the attribute information of the file, and the attribute information of the file is stored in the form of key-value pairs (key-value). In the new file format, the two are organized through the file structure description block,

[0035] Such as figure 1 As shown, the logical structure of the organized new file format is divided into three parts:

[0036] 1) File structure description block, including three parts: internal description block, attribute block bitmap (Attribute Bitmap) and data block bitmap (Data Bitmap). The internal description block is used to describe the internal structure of the file, the distribution of file data and metadata, and other information. The attribute block bitmap and the data block bitmap store the position information of the attribute block and the data block and the corresponding block size informat...

Abstract

The invention belongs to the field of computer data storage, and particularly relates to a method for organizing and managing file content and metadata. The method is characterized in that the self organization and the self management of the metadata are realized in a file, so that the file has a self-describing property, and trust on a specific format, a database and the like is eliminated. Compared with an original file, the file in the method is additionally provided with a file structure description block and a file attribute block. A user sends a file access request to find a corresponding target file. The information of the file structure description block is extracted, and the file content or the file attribute is read or written by a data block bitmap and an attribute block bitmap in the information of the file structure description block according to the choice of the user. With the method disclosed by the invention, attribute extension and semantic association can be conveniently supported to provide support for information retrieval and a semantic structure is supported, and therefore the efficient file retrieval of a huge quantity of unstructured data can be realized.

Description

technical field [0001] The invention belongs to the field of computer data storage, in particular to a method for organizing and managing file content and metadata. The method combines and stores the file content and metadata, realizes the organization and management of the file content and metadata inside the file, and makes the file self-describing. Background technique [0002] With the development of information technology, new data types continue to emerge, including a wealth of metadata (metadata), which is used to describe the content, coverage, quality, management methods, and data structure of elements, datasets or dataset series. Information about the owner, how the data was provided, etc. The self-describing ability of traditional file system technical information is not strong, it does not provide sufficient support for metadata extension, and cannot provide information on the semantic structure of files for the operating system, resulting in users being unable ...
