IEC 62919:2017 pdf download.Content management – Monitoring and management of personal digital content
1 Scope
This document specifies requirements, the protocol and the data format to visualize personal content saved on the various devices, such as mobile phones, music players, personal computers, hard disk recorders and e-book devices. This document also specifies methods for gathering information of digital content saved on personal devices and shared within a group, and to extract the gathered information by uniform application interface.

3 Terms, definitions and abbreviated terms
3.1 Terms and definitions For the purposes of this document, the following terms and definitions apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: • IEC Electropedia: available at http://www.electropedia.org/ • ISO Online browsing platform: available at http://www.iso.org/obp 3.1 .1 content preservation information information on content that is preserved in a user’s device 3.1 .2 content information server server which receives and stores content preservation information 3.1 .3 personal content digital content stored on user devices Note 1 to entry: Personal content includes content that users purchase or create by themselves. 3.1.4 content device user device where content is stored 3.1.5 device ID identifier to specify a device 3.1 .6 user ID identifier to specify the user in the system 3.1 .7 family ID identifier to specify a group where digital content can be shared Note 1 to entry: Family ID is not necessarily used for a family group. It can be applied not only to a family, but also to friends, colleagues and other groups. 3.1.8 my library application viewer to monitor and manage all content that a user has on their own device
4 Basic system structure
4.1 View of digital content Clause 4 shows the system behaviour and operations to visualize and monitor all digital content that users have. The system behaviour and operations are listed as follows. a) Each device sends out the content preservation information to the content information server, which gathers the information on digital content saved on the device. b) The content information server receives and stores the content preservation information. The saved content preservation information can be extracted in user ID units. Figure 1 shows the system behaviour on a) and b) in 4.1 .c) The content information server provides an interface that enables other servers to extract content information in user ID units. The same or other servers can use the interface to create the HTML format on my library and send it to the monitoring devices. The interface also enables other servers and service providers to get, search and analyze users’ content usage information or content preference information. Figure 2 shows the interface on c) in 4.1 .e) The web server distributes the information on my library to the monitoring devices in user ID units. f) If users acquire new digital content, the users’ content preservation information is changed. In that case, the change is notified to the monitoring devices appropriately and the monitoring devices render the change and modify its view. g) The content information can be shared among other users in a group, such as a family, a household or colleagues. NOTE 4.1 d), e), f) and g) indicate the operations to distribute and render the content information on my library. They are dependent on the implementation and improvement. Therefore, d), e), f) and g) are out of scope and described as informative in this document. 4.2 Consumption of digital content If users want to access or consume digital content from my library, the application sends a request for content delivery to the content server or other devices. Its access methods can be implemented over the existing, or new, technology. Figure 4 shows an overview on how to consume digital content on my library.
