BS EN IEC 62919:2018 pdf download.Content management - Monitoring and management of personal digital content
5.1 General
Users register their user lDs and their devices with a central server or a cloud server. User ID and device ID are used for the communication between the server and the client's device.
5.2 Required functionalities
5.2.1 Content devices
A content device creates content preservation information by reading out necessary data in content format and sends it out to the content information server.
When the content preservation condition is changed on the content devices, the content devices send out the modification information to the server. That enables my library to display the latest condition of the stored content.
5.2.2 Content information server
Content information servers provide APIs by which other servers can retrieve content usage information, users' preference information and users' attribute information by user units. The content information server cooperates with online storage services when the users wish to consume digital content.
Content information servers can manage and implement users' access control based not only on user IDs, but also on family IDs.
5.2.3 Personal content monitoring device
When users modify the view structure or arrangement of my library on the monitoring devices,the monitoring devices save the customized change information or upload it to the content information server.
6.1 Protocol
In this document, it is expected that a web browser can be the application of my library for visualizing personal content. The HTTP or HTTPS protocol is used to communicate from content devices to the content information server as shown in Figure A.1. Since the HTTP or HTTPS protocol is used for internet browsing, users do not need to change the port setting on their broadband routers or their gateway routers in their home and domains.
6.2 Application layer
6.2.1 General requirement
Users would like to sort or rearrange content icons on my library by drag and drop operations,such as operations on actual bookshelves. Addition, modification and deletion of content saved on the devices should be notified to the client (visualization application) in asynchronous communication.
In addition, the client devices to visualize personal content should display the content preservation information, even if it is offline.
Figure 5 shows an example of the personal content view of my library.
6.2.2 HTML5
It is expected that the HTML 5 protocol be used for visualizing personal content because objects on web browsers can be moved by drag and drop, and it can implement asynchronous communication. The application using HTML5's local storage can work offline once the application receives the list of personal content.BS EN IEC 62919 pdf download.
