Title: Re-issue
of the Call for Requirements for a Rights Data Dictionary and a Rights

Source: Requirements
Status: Approved
Call for Requirements for a Rights Data Dictionary
and a Rights Expression Language (Re-issue)
Addendum
This Call for Requirements was first issued in
January 2001 following the MPEG meeting in Pisa. A number of the submissions
which were received in response to this Call requested that a longer period of
time should be granted for responses to be submitted. This would enable those
who wish to respond to have longer for consultation in order to prepare their
requirements submission. In view of these requests MPEG has decided to re-issue
the Call for Requirements until Friday, 1st June. In addition, in order to progress the
work and ensure the widest possible consultation, MPEG will be arranging an
‘ad-hoc’ meeting to be held on 7-8th June, in London, to which
interested parties, including the submitters of responses, are invited to
attend.
Fourteen responses to the Call for Requirements
from the January meeting in Pisa were received. These were assessed during the
MPEG meeting held in Singapore during March and a list can be found in Annex A
which is attached to this Call. Many of these responses contained substantial
contributions which have been consolidated to construct a first draft of the
requirements. This document is N4045, which is in the zip file as W4045 (RDD-REL Reqs).doc. for information and it is proposed that it will form the basis for
further elaboration at the ‘ad-hoc’ meeting in London and finalized and
approved at the next MPEG meeting in Sydney in July. All respondents to this
Call for Requirements are welcome to attend this meeting, and to take part in
the discussions.
The London ‘ad-hoc’ meeting will be hosted by
the International Federation of the Phonographic Industry (IFPI) at their
offices in London. Those who intend to attend the meeting are required to
register their attendance no later than 25 May 2001with the coordinator:

Introduction to the Call for Requirements
MPEG, a working group in ISO/IEC, has produced three
important standards (MPEG-1, MPEG-2 and MPEG-4) and is working on MPEG-7 and
MPEG-21. Extension work is ongoing on the ‘Intellectual Property Management and
Protection’ (IPMP) specification in MPEG-4, with the goal to enhance
interoperability in the consumption of protected content. The Content
Description Standard MPEG-7 is in Final Committee Draft status, to be completed
by the end of 2001. The ‘Multimedia Framework’ MPEG-21 standard is in an
initial development phase, with the Requirements phase in an advanced stage and
the first Call for Proposals issued in October 2000. MPEG has a long history in
working with members of the creative industries and rights holders’ communities
on the identification, management and protection of intellectual property carried
on systems designed to MPEG specifications. This started with work on the
MPEG-2 standard, which was finalized in the year 1994 and has continued
throughout the development of MPEG-4. Participation is ongoing in MPEG-7, and
these communities have been involved in MPEG-21 from its inception.
MPEG has identified the need for a Rights
Expression Language and a Rights Data Dictionary in the context of three of its
standards:
ú
MPEG-4, for the IPMP extension,
ú
MPEG-7, to describe, as a part of content
descriptions, the conditions to access content, and
ú
MPEG-21, to achieve the goal of expressing
rights for all Users of MPEG-21’s so-called ‘Digital Items’. (Users refers to
both End Users and parties such as creators, producers, distributors, rights
holders, etc.)
Note that ‘Rights’ is understood to
include permissions.
While MPEG has identified the need for such a language and dictionary, the
requirements are not yet well enough understood to issue a Call for Proposals.
Hence, MPEG is now asking interested parties and experts to submit requirements
for this technology to MPEG, and invites these parties and experts to take part
in the work. MPEG seeks these inputs by Friday, 1st June, in
preparation for an MPEG ‘ad-hoc’ meeting to be held
in London on 7-8th June 2001.
MPEG currently anticipates issuing a Call for Proposals, based on the
collected Requirements, at its 57th meeting, in July
2001. Further timing will be decided when the requirements are better
understood.
Any input on these requirements is welcome, and submissions do not need to
address both the language and the dictionary. MPEG’s sees a Rights Data Dictionary as a dictionary of key terms which are
required to describe rights of all Users, including intellectual property
rights, that can be unambiguously defined using a standard syntactic
convention, and which can be applied across all domains in which rights need to
be expressed. A Rights
Expression Language is seen as a machine-readable language that can express rights
and permissions using the terms as defined in the Rights Data Dictionary.
Parties that are
not familiar with MPEG are kindly requested to send their requirements, by
email, to Rob Koenen (Chairman MPEG Requirements Group,) and Keith Hill (Leader
of the MPEG-21 Requirements activity) by Friday
1 June, 23:59 hours GMT. The document type commonly used in MPEG is Microsoft
Word, while plain text (ASCII) documents are also acceptable. If this would
form a problem, then please contact Rob Koenen to work out an alternative way
of submitting your requirements. Your contribution will be made available to
all meeting participants, so that there can be an informed discussion. You will
also be given the opportunity to present your requirements to the meeting.
Those parties that are familiar with the
MPEG process and have access to the FTP site are kindly asked to use the normal
MPEG submission process, and notify Rob Koenen and Keith Hill about their
submission by Friday 1 June, 23:59 hours GMT. Email is the preferred means of
communication.
Annex A to this Call for Requirements contains a short Problem Statement.
An ‘Overview of Intellectual Property Management and Protection in MPEG’ is
included for information as a separate attachment.
Annex B contains the draft requirements as
developed during the MPEG Singapore meeting in March based on the responses
that had been received at that time. This should be considered to be a ‘work in
progress’ that will continue to be refined using any further responses received
as a result of the re-issue of this Call.
Responses to the Call for Requirements are
encouraged to be presented in the following format:
|
Requirement: |
|
The RDD-REL shall support all operations throughout the entire life cycle
of Digital Items including creation, publishing, distribution, consumption,
and invalidation/disposal. |
|
Note: |
|
A
standard vocabulary and a consistent, ordered and
machine-readable language is required for describing both the upstream and
downstream rights associated with Digital Items. Management of Rights Descriptions
will be more exact by addressing each stage of the life cycle of Digital
Items and the respective roles of the Users. In this way each User can define
each life cycle category of rights independently. |
|
Example: |
|
NB: The ‘Requirements’ part is always present, the Note(s) and
Example(s) are optional.
Submitters are also encouraged to provide
any additional information that might be relevant to support this requirements
gathering work and to provide comments on the requirements as they have been
defined so far in Annex B.

Annex A – Background Information and Problem Statement
A number of recent projects and proposals for projects have recognised the need for standard ways of expressing information about intellectual property rights in the machine-to-machine network environment. These proposals have typically focused on a relatively small segment of the overall problem, such as usage permissions expressed by producers and publishers down the delivery and value chain (‘downstream rights’). Some parties believe that also being able to define and manage the rights of creators and their relationship with producers and publishers (‘upstream rights’) is a prerequisite for managing the downstream rights and permissions. Note that these are highly complex relationships, described here in a simple model to communicate the reason for this Call.
To achieve the goal of being able to manage both upstream and downstream rights, it is necessary to develop a consistent, ordered and machine-readable language for describing the rights in intellectual property from the beginning. In this fashion, permissions for such actions as print, copy, play, etc., can be meaningfully implemented across the networked environment. For unless the rights granted by creators through contracts can be expressed in a machine-readable language, the downstream permissions granted to users through Digital Rights Management (DRM) processes will be limited by what can be conveyed on the basis of contractual databases that rely on a conversion of original paper-based expressions into local and probably proprietary machine readable languages.
Furthermore, unless a standard language is developed, DRM systems will be forced to interpret contractual expressions from different origins describing the same types of rights in different terms. With the vast number of corporate rights holders in publishing, broadcasting and the still image industries, each with a different contract system, the lack of a standard language would cause contractual chaos.
The fundamental issue is that rights do not operate in a discrete space. Not only is “rights management” a continuum from creator to user, media convergence mandates that rights management solutions must look beyond individual media sectors to cover the IP industries as a whole. The object-based MPEG-4 standard allows for the packaging of ‘digital objects’ of various types from many different sources, which suggests that an integrated approach is required. And as usage permissions innately rely on the original rights granted, unless there is a machine-readable continuum, it will be difficult to arrive at automated rights transactions.
Since the beginning of 2000, a number of attempts have
been made to develop a model that would bring together all interested parties
in an effort to move rights management standardisation efforts forward,
specifically to create an understanding of the “rights continuum”. The <indecs>
project provided an underlying analysis of the generic requirements for rights
management metadata. However, <indecs> could not fully complete the
development of the model that built on this analysis.
Recent developments within MPEG, and also within Open e-Book Forum (OeBF), indicate that the need to deal with the upstream rights issues is now more widely appreciated. One way to address these issues has been articulated within MPEG-21; this calls for the creation of an extensible dictionary and language for the expression of semantic sets of rights definitions. This approach (described in the MPEG-21 documentation [1]) contains the following steps:
1.
Adopt or extend existing rights expression
languages, where appropriate, for describing contractual usage rules for
Digital Items. Start from the work being done in MPEG-7, but develop new
languages if needed.
2.
Expand these languages to allow the
expression of rights and interests in personal data.
3.
Expand these languages to allow the
expression of public policies and rules stemming from sources other than Rights
Holders, such as governments and other relevant rule-making bodies. This work
item may require more time than available in the first phase of the development
of MPEG-21. As soon as time and resources are available, this item should be
undertaken.
Note that point 2 highlights the need for end users to be able to express their rights and interests. MPEG-21 lists this only as a possible approach; other approaches are also conceivable. A decision has not yet been taken, and the action plan in MPEG-21 will very much depend on the collected requirements.
In addition to the issues
with upstream rights articulated above, the public is growing increasingly
concerned with issues of privacy and the use and abuse of personal
information. Clearly, the
collective requirements must adequately address the rights of the full spectrum
of all parties involved in the exchange or transfer of content, including end
users, creators, publishers, producers, aggregators and distributors.
Similar requirements have been identified in the context of MPEG-7 [2]:
Usage rules - MPEG-7 shall contain
Descriptors/Description Schemes that provide information on how content may be
used.
Note: Such a feature may provide
considerable consumer benefit by, for example, providing pre-purchase
information. It may also enable different creative sectors to achieve
interoperability between the providers of similar services. However, it should
be noted that MPEG-7 cannot override the usage rules associated with the
content itself which will be governed by the usage rules of its own management
and protection system.
Lastly, the need for a rights expression language using an appropriate
dictionary has been flagged in the work on a more interoperable Intellectual
Property Management and Protection (IPMP) specification for MPEG-4 [3].
