Why is the electronic document text file the preferred archiving format?

In terms of format selection, it is generally required to form, collect and archive electronic files in a common format, or to convert electronic files into a common format before archiving.

The filing format of electronic documents should have the characteristics of open format, no binding between software and hardware, consistent display, conversion and easy use, and can support the conversion of national archives at the same level to long-term storage format.

"Universal" means that the electronic file filing format should be able to display and browse normally on most computers. To this end, the format of electronic documents should conform to national standards or international common standards.

"Openness" means that electronic files adopt open format standards, and anyone can analyze and browse electronic files normally according to the open file standards. If this can be done, electronic files can be freely converted and migrated regardless of the development of computer software and hardware. Only in this way can we truly realize the goal of long-term preservation of electronic files.

Typesetting electronic files and streaming typesetting files

Format computer files adopted by business system should meet the requirements of 1 1 specified in the format requirements for long-term preservation of formatted electronic files (DA/T47-2009), and the computer files with the required formats are OFD, PDF and PDF/A..

Electronic files stored in computer file format with layout are presented in the form of pages, and the typesetting format and color are attached to the format. Once formed, the typesetting format is solidified and cannot be changed, and information such as words and pictures can no longer be inserted into it, and the color presentation has nothing to do with computer equipment.

Corresponding to the format file is a streaming typesetting file, which can also be called a streaming file. Text files stored in computer file formats such as RTF, WPS and DOC are stream files. After you have finished the layout and font setting of characters, numbers, tables and images in the stream file, you can continue to insert new content anywhere.

Information such as the original text behind the new content will automatically flow downward and automatically adapt to the set boundaries without affecting the original typesetting elements such as font, font size and color.
