7 Naming and storage

7.1 Naming rules The encoding of the video file name should include the project code, document code, structure code and resource level code, as shown in Figure 1. XXXXXXXX-XXXXXXX-XXXXX-X/XX Literature code Structure code Resource level Project code Figure 1 Video resource naming and coding The detailed description of each part of the video resource naming coding is as follows. a) Project code. The project code should be in the form of "project number project year". b) Document code, which represents the number of the video resource processed in the year of the digitization project (the unique identifier of the video resource). c) Structure code, structure code consists of structure code serial number. 1) The structure code is a single letter, which represents the structure information of the object data, see Table 10 for details; 2) The smallest unit of the object data expressed by the serial number after the structure encoding; 3) No connection symbol is required between the structure code and the serial number. d) Resource level code. The resource level code represents the application level of the resource. One or two digit codes should be used, including. 1) The long-term storage level is indicated by the letter A. 2) The release service level is represented by the letter D.  Advanced. It is represented by the letter DH;  Intermediate. It is represented by the letter DM;  Low level. It is represented by the letter DL. Table 10 Structure code table Number structure coding description 1 A CD cover of video materials, screenshot cover of network resources, etc. 2 B video clips, etc. 3 C clip catalogue of video materials, etc. 4 T Video clips. 5 X video materials printed attachments, physical resources related explanations and research materials. 6 Y video footage recordings, etc. 7 Z Disc back cover for video materials, etc. 7.2 Storage The project is an independent storage structure, and all documents are stored in it. The storage system is shown in Figure 2.
