CONTENT MANAGEMENT –
MONITORING AND MANAGEMENT
OF PERSONAL DIGITAL CONTENT

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in
addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses
arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
Users have ICT devices on which they store various digital content, such as movies, photos,
music, e-books and documents. Since the capacity of each ICT device is getting larger and
online storage services are provided, digital content can be stored on a wide range of devices.
Users also create backup copies of digital content on multiple devices. That causes the
production of multiple generations of digital copies from an original and the digital content can
be put somewhere in any order. As a result, digital content goes into hiding and users can be
unaware of the location where the digital content is stored. Therefore, users have difficulties in
searching for and finding the digital content they want, or it takes a lot of time to find the content.
Since users may forget the provenance of the digital content saved on their devices, the
information to identify the distribution channel is helpful for the users.
Even if users can easily recognize digital content, its location or its directory on a specific device,
it is not enough to solve the difficulties.
This document specifies the method in which each device makes content preservation
information in the specified format and sends it to the server system. The operation enables the
visualization of all their digital content, which is separately stored on various devices, and an
easy way to find the desired content.
In addition, the central server, which gathers the content preservation information from many
users’ own devices, provides the interface to derive the summary from the gathered information.
By deriving users’ content preservation information, a service provider can analyse the users’
usage and preference information, and it helps launch new flexible digital content distribution
structures.

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.
IEC

Figure 2 – Request for extracting content information
d) The monitoring device requests the web server to send the information on my library, as
shown in Figure 3. The web server gets content preservation information via the interface
provided on content information server and creates the HTML format.

Figure 3 – Request for viewing digital content
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.

IEC
Figure 4 – Consumption of 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 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 General measures for visualizing personal content
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.
IEC

Figure 5 – Example of view of my library
6.2.2 HTML5
It is expected that the HTML5 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.
6.2.3 Improved view of my library
If there is the same content on different content devices, the view application may indicate the
presence of copies in some way, such as different colours or balloons on icons.

7 Sending content information to servers or cloud
7.1 General
7.1.1 Content meta 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 Content meta information
Content meta information includes the items listed as follows:
• 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 includes the items listed as follows:
• filename,
• filepath,
• application type,
• create time,
• size, and
• title.
An application type that is registered in RFC6
