BS EN IEC 62919:2018 pdf download.Content management – Monitoring and management of personal digital content.
5 Requirements
5.1 General
Users register their user IDs 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 chant’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 send5 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 inlormahon 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 contenL
Content information servers can manage and implement users’ access control based not only on user IDe. but also on family IDe.
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.
7 Sending content Information to servers or cloud
7.1 General
7.1.1 Content mite and base information
Content preservation information, which each device sends to the content information server.
includes the items listed in 7.1.2 and 7.1.3.
7.1.2 Cont.nt m.ta Information
Content mete information
• method,
• device ID/device name.
• user ID,
• family ID,
• content ID. and
• sub-content ID (global ID identified in content distribution market).
After the content preservation information is stored in the content information server, family ID can be settled on the server system. For instance, users access a website on the server system, they select a family ID from the candidates to confirm a group for content sharing. Family ID is an identifier that can be applied to not only a family, but also friends, colleagues and other groups.
When a device Is registered In the system, the user can add its device name to the system. A name-resolving server runs In the Cloud system and manages the table between the device ID and the device name. The correspondence between the device ID and the device name helps name resolving in the system, as needed.
Content IDs may consist of two IDs that are a content ID and a sub-content ID, The sub-content ID is the identifier allocated globally in the content distribution market. The server in the cloud system can derive the content metadata from the sub-content ID. The derivation or reference operations between the sub-content ID and the content metadata will be conducted only on the server side.
7.1.3 Content base information
Content base information .ccontent baseinfo> includes the items listed as follows:
• filename.
• filepath.
• application type,
• create time.
• size, and
• title.
An application type that is registered in RFC6838 as a media type can be used to launch the correct program to consume digital content. Application types are regarded as classification of application programs that work on devices. When the content information server receives the content preservation information including the application type, the server saves the data as shown in Table 1
7.2.1Basic structure content preservation information
Users’devices put the content preservation information in the XML format indicated in Figure 6and send it to the content information server. A device lD shown in Figure 6 is identical to thesender device lD.The device can put content information in a
