Background technique

Metadata is data that describes the context, content, structure of a file and its entire management process. Different from description in the traditional sense, metadata has richer connotations, more comprehensive functions, and stricter requirements. It is impossible for archives managers to record after the documents are filed, and it is even more impossible for file managers or business personnel to manually enter them. Metadata needs full planning, needs to be embedded in the system, needs to be automatically collected in real time, and needs to truly and dynamically reproduce the background information and process information of electronic file management. Achieving automatic collection of metadata is a requirement for the management of metadata itself, as well as a requirement for forming the actual business of an organization.

A method for collecting metadata of electronic files with good compatibility, comprising the following steps:

S1: Understand the format and attributes of the original electronic file, and use the data processing capability of the microcontroller to classify files of different formats into two types: identifiable source files and unrecognizable source files. The single-chip microcomputer transmits the two types of files to the data processing center.

S2: For the data of the identifiable source file, first obtain the layout structure of the target data, and then locate and read the target data according to the generally recognized and determined file reading rules.

S3: For files with unrecognized source files, they are divided into two types of source files with high compatibility and poor compatibility according to compatibility. Establish corresponding data extraction rules to extract target data. For source files with poor compatibility, manual intervention needs to be triggered, and engineers can write corresponding conversion tools to read them.

S4: The data processing center saves the data read in S2 and S3 in a common format, and then transmits it to the metadata database for storage.

S5: The data processor in the metadata database sorts the data. First, the sorting is divided into three types: accurate data, redundant data and incorrect data. For accurate data, it will be directly input into the new database. For redundant data, the data processor Reset and calibrate it, then filter out the calibrated data in the redundant data, and input the remaining data into the new database. For wrong data, the administrator needs to intervene to determine the correct items and errors in the wrong data. Items are then modified by the administrator before they are entered into the new database.

S6: The EDS encryption server encrypts and protects the data in the new data. Departments in the enterprise can encrypt and download all data in the new database from the OA server. All data in the new database can be encrypted and downloaded on the client through the Internet .

The data extraction rules in S2 and S3 are based on the basic principles of file management and the management rules based on electronic files, including the principle of source, the principle of organic association and the principle of front-end control; the redundant data in S5 may contain data items with similar indicators but different meanings When calibrating redundant data, it is necessary to determine in the original electronic file, which data are basic data and which are excerpted data, and the latter can be calibrated as redundant data.

Although metadata collection reveals the content of documents and archives and their production rules by collecting, refining, analyzing and organizing electronic file information, it is still based on the premise of respecting the essential attributes and laws of archives, and it pays attention to reflect the source of electronic files when collecting. , so that the electronic documents of the same source in the organization can be reflected in a centralized manner through the collection of metadata, so that the metadata is related to the source of the archives, so as to reveal the various connections between the archives and documents of the same source through the metadata, which is the basis for the archives and documents. The understanding and utilization of the system provide background information on the source; the principle of organic connection is also the basic principle of archives management, which means that the documents in the system and the elements that make up the system need to maintain the relationship in time and space. Since electronic files are scattered in the computer in the form of binary codes, it is particularly important to maintain the organic connection between files, and to maintain this organic connection, metadata must be relied on; as far as metadata collection is concerned, in the The organization of the electronic document management system has been established. Electronic documents are generated and operated in the system. The front-end of electronic document metadata collection is "advanced" to the design stage of the system, and the form of front-end control is also partially transferred to the design of system functions. That is, the metadata requirements of each stage of the file life cycle are designed into the system as much as possible, and the OA system with reasonable functions is used as a prerequisite for managing electronic files.

Learn what the raw data attributes and corresponding metrics mean exactly. This is the basis for collecting raw data. Some data indicators have undergone a process of continuous adjustment. Therefore, it is necessary to first understand the properties, structure, exact meaning, scope of inclusion, and the adjustment relationship between the previous and subsequent time periods of the original data, and determine the required data items and data extraction principles.

Data sorting is the most time-consuming but also the most critical step in the data preprocessing process. In general, the acquired raw data will have various problems or defects, which must be sorted out before the next processing. Data redundancy is manifested in a In a time period or a data series, there are data items with the same indicator meaning and the same data, or data items with different indicator names but the same meaning and the same data, but it should be noted that redundant data may contain data item indicators For similar data with different meanings, when calibrating redundant data, it is generally necessary to determine in a set of reports or original databases, which data are basic data and which are excerpted data, and the latter can be calibrated as redundant data.

Data errors. For such errors, the key is to find out the wrong data items in the balance relationship and modify them. Generally, with reference to other reports in a set of reports or other data in the same period, first determine the correct data items and the position of the wrong data item, for example, determine whether the total data is wrong or the sub-item data is wrong, and then, through the method of backward calculation, determine the value of the wrong data in the data balance relationship and correct it. In actual operation, this approach should be used with caution Also, be careful, keep a record for each step for returning to the previous state at any time, so as not to cause larger errors, so administrators are required to intervene.

The software environment will contain a large number of logical audit formulas. For example, the original software environment can still be reconstructed, and the missing supplement or error correction of electronic data should be carried out in the original system, which can effectively reduce the workload and improve the data accuracy. For paper data, you can also use computer spreadsheet software to establish a corresponding logical review relationship, and input the paper data into the computer for review and modification, which can greatly improve efficiency. The data will lose its use value or cause negative effects. Remarks must be made for the deleted, modified and estimated data, and a data modification file must be established for future reference.

It should be noted that, in this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any relationship between these entities or operations. any such actual relationship or sequence exists. Moreover, the terms "comprising", "comprising" or any other variation thereof are intended to encompass a non-exclusive inclusion such that a process, method, article or device that includes a list of elements includes not only those elements, but also includes not explicitly listed or other elements inherent to such a process, method, article or apparatus. Without further limitation, an element defined by the phrase "comprising a..." does not preclude the presence of additional identical elements in a process, method, article or apparatus that includes the element.
