For example, the user device 103 may acquire the content indicated by the variable I after acquiring the system common information corresponding to the content indicated by the variable I from the information processing device 102. Before performing the process of the next step S506, the user device 103 may acquire the content indicated by the variable I and the system common information corresponding thereto from the information processing device 102.

In step S506, the user device 103 executes the process related to the content acquired in step S504 by using the system common information acquired in step S505. For example, the user device 103 acquires the image content in step S504 and acquires the shooting date and time information as system common information in step S505, thereby performing a process of storing the image content in folders according to the shooting date and time. ..
In step S507, the user device 103 adds 1 to the value of the variable I and returns the process to step S503.

By doing so, the user device 103 can execute the processing related to the content by utilizing the system common information stored in advance without analyzing the container of the content acquired from the information processing device 102. It becomes. In the above-mentioned example, the shooting date and time in the image content is illustrated as system common information, but it may be a normal file generation date and time or other attributes, and is not limited to the above-mentioned example.

Further, the user device 103 may be a server device, and the write authority may be granted so that the system common information can be written to the information processing device 102 in step S506. Further, in step S505, when the user device 103 fails to acquire the system common information from the information processing device 102, the user device 103 re-requests the information processing device 102 for the system common information. You may try to do it. Further, in step S505, when the system common information does not exist in the information processing device 102, the user device 103 may execute the system common information re-creation request process for the information processing device 102.

In the above-described embodiment, the information processing device (content management) 102 that stores the content and the system common information performs a process of acquiring the system common information from the uploaded content. However, it is not limited to this. For example, as shown in FIG. 6, the process of acquiring system common information from the uploaded content may be performed by an information processing device 601 or an application different from the information processing device (content management) 102. The information processing device 601 receives the uploaded content from the information processing device (content management) 102, analyzes it, acquires system common information (S611), and transfers the acquired system common information to the information processing device (content management) 102. Output (S612). For example, it is assumed that the information processing device 601 analyzes the content of the image, acquires the subject information (subject type, size, color, etc.) and outputs it to the information processing device 102 as system common information. NS. Then, even if the information processing device (content management) 102 stores and manages the content uploaded from the user device 101 such as an external device in association with the system common information acquired by the information processing device 601. good.
