Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission)
form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC
participate in the development of International Standards through technical committees established by the
respective organization to deal with particular fields of technical activity. ISO and IEC technical committees
collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in
liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have
established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International Standards
adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.
ISO and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 21000-6 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 29, Coding of audio, picture, multimedia and hypermedia information.
ISO/IEC 21000 consists of the following parts, under the general title Information technology — Multimedia
framework (MPEG-21):
 Part 1: Vision, technologies and strategy
 Part 2: Digital item declaration
 Part 3: Digital item identification
 Part 5: Rights expression language
 Part 6: Rights data dictionary
 Part 7: Digital item adaptation
The following parts are under preparation:
 Part 8: Reference software
 Part 9: File format
 Part 10: Digital item processing
 Part 11: Evaluation methods for persistent association technologies

Introduction
Today, many elements exist to build an infrastructure for the delivery and consumption of multimedia content.
There is, however, no 'big picture' to describe how these elements, either in existence or under development, relate
to each other. The aim for MPEG-21 is to describe how these various elements fit together. Where gaps exist,
MPEG-21 will recommend which new standards are required. ISO/IEC JTC 1/SC 29/WG 11 (MPEG) will then
develop new standards as appropriate while other relevant standards may be developed by other bodies. These
specifications will be integrated into the multimedia framework through collaboration between MPEG and these
bodies.
The result is an open framework for multimedia delivery and consumption, with both the content creator and
content consumer as focal points. This open framework provides content creators and service providers with equal
opportunities in the MPEG-21 enabled open market. This will also be to the benefit of the content consumer
providing them access to a large variety of content in an interoperable manner.
The vision for MPEG-21 is to define a multimedia framework to enable transparent and augmented use of
multimedia resources across a wide range of networks and devices used by different communities.
This sixth part of MPEG-21 (ISO/IEC 21000-6) specifies a Rights Data Dictionary for use within the MPEG-21
Framework. This Rights Data Dictionary forms the basis of all expressions of rights and permissions as defined by
the MPEG-21 Rights Expression Language (specified in ISO/IEC 21000-5).

INTERNATIONAL STANDARD ISO/IEC 21000-6:2004(E)

Information technology — Multimedia framework (MPEG-21) —
Part 6:
Rights Data Dictionary
1 Scope
This part of ISO/IEC 21000 describes a Rights Data Dictionary which comprises a set of clear, consistent,
structured, integrated and uniquely identified Terms (as defined in Clause 5.4) to support the MPEG-21 Rights
Expression Language (REL), ISO/IEC 21000-5. Annex A specifies the methodology for and structure of the RDD
Dictionary, and specifies how further Terms may be defined under the governance of a Registration Authority,
requirements for which are described in Annex C.
Taken together, these specifications and the RDD Dictionary and Database together make up the RDD System.
Use of the RDD System will facilitate the accurate exchange and processing of information between interested
parties involved in the administration of rights in, and use of, Digital Items, and in particular it is intended to support
ISO/IEC 21000-5 (REL). Clause 6 describes how this part of ISO/IEC 21000 relates to ISO/IEC 21000-5.
As well as providing definitions of Terms for use in ISO/IEC 21000-5, the RDD System is designed to support the
mapping of Terms from different namespaces. Such mapping will enable the transformation of metadata from the
terminology of one namespace (or Authority) into that of another namespace (or Authority). Mapping, to ensure
minimum ambiguity or loss of semantic integrity, will be the responsibility of the Registration Authority,
requirements for which are specified in Annex C. Provision of automated Term look-up is also a requirement.
The RDD Dictionary is a prescriptive Dictionary, in the sense that it defines a single meaning for a Term
represented by a particular RddAuthorized TermName, but it is also inclusive in that it can recognize the
prescription of other Headwords and definitions by other Authorities and incorporates them through mappings. The
RDD Dictionary also supports the circumstance that the same name may have different meanings under different
Authorities. ISO/IEC 21000-6 describes audit provisions so that additions, amendments and deletions to Terms and
their attributes can be tracked.
ISO/IEC 21000-6 recognises legal definitions as and only as Terms from other Authorities that can be mapped into
the RDD Dictionary. Therefore Terms that are directly authorized by the RDD Registration Authority neither define
nor prescribe intellectual property rights or other legal entities.
1.1 Organization of the Document
This document contains six Clauses and four Annexes.
Clause 1 contains a Scope statement and three sub-Clauses.
Clause 2 comprises a list of Normative References.
Clause 3 comprises a list of Terms and Definitions. The Terms and Definitions in this Clause are only those
required to navigate the text of the Standard. The Terms of the RDD Dictionary are contained in Clause 5.
Clause 4 describes the documentation conventions used in this document.
Clause 5 contains the Standardized Terms of the RDD Dictionary, set out in the following sub-clauses:
Clause 5.1 – Introduction to the Terms in the RDD Dictionary and the ontology which it embodies. An ontology, in
this context, is a structured catalog of entities in which meaning, once defined, can be passed on from one term to

ISO/IEC 21000-6:2004(E)
another by logical rules of association such as inheritance and opposition. The process by which the RDD
Dictionary is structured and can be extended is contained in Annex A.
Clause 5.2 – A table of the fourteen RELStandardardizedActTypes which provide the semantic content of the
corresponding REL Multimedia Extension Rights. Each of these RELStandardizedActTypes is included in the full
RDD Dictionary in Clause 5.4 but they are separated out here for ease of reference, as they are normatively
referenced in the REL Standard (ISO/IEC 21000-5).
Clause 5.3 – A Figure (Figure 1) in the form of a hierarchical table including the principal ActTypes in the RDD
Dictionary (“The RDD Family Tree”) showing how meaning is inherited from one to another within the RDD
ontology.
Clause 5.4 – A table (Table 2) containing the RDD Dictionary of StandardizedTerms with their Attributes. The RDD
Dictionary includes all the Terms that are required to support the REL Multimedia Extension Rights, and also all the
Terms that are required to support the process for adding new Terms, as specified in Annex A.
Clause 6 describes how this part of ISO/IEC 21000 relates to ISO/IEC 21000-5.
Annex A (normative) specifies the methodology for and structure of the RDD Dictionary, providing information
about the supporting model, how the model is used to introduce Terms to the RDD Dictionary and how those
Terms are related. It also shows how further Terms may be defined under the governance of a Registration
Authority, requirements for which are described in Annex C.
Annex B (normative) provides Rules and Style Guides for Textual Elements, in support of the methodology of
Annex A.
Annex C (normative) describes the requirements for a Registration Authority for the RDD Dictionary.
Annex D (informative) provides examples of how this part of ISO/IEC 21000 can be applied, with illustrative
examples of an Action Family, and an exemplary specialization of an ActType mapped from an external dictionary.
Annex E (informative) provides patent statements relating to ISO/IEC 21000-5.
For information about the Terms in the RDD Dictionary and their relationship to ISO/IEC 21000-5, it is necessary to
read the six Clauses.
For information about the methodology of the RDD Dictionary and the ontology upon which it is based, it is
necessary to read Annexes A and B.
For information about the requirements for the Registration Authority, which will govern the process of extending
the dictionary, it is necessary to read Annex C.
For examples of how the RDD Dictionary can be implemented for the development of new Terms and their use in
the REL, it is necessary to read Annex D.
1.2 Relationship between this part of ISO/IEC 21000 and other parts of the MPEG-21 Framework
(Informative)
At present the only specific relationship with other parts of ISO/IEC 21000 is with Part 5, the Rights Expression
Language. A description of this relationship is set out in Clause 6.
1.3 RDD Term Identifier Prefix
The RDD Term Identifier Prefix will be urn:mpeg:mpeg21:2002:01-RDD-NS. The "01" represents a serial
number that may be expected to change consequent upon the maintenance activities of the Registration Authority.

3 Terms and Definitions
For the purposes of this document, the following terms and definitions apply.
Terms in this International Standard, which have initial capital letters, have formal definitions either in this Clause or
in the Rights Data Dictionary itself in Clause 5.4 (Table 2).
Because this part of ISO/IEC 21000 is concerned with the definition of terms, most of the Terms used in describing
the International Standard are themselves StandardizedTerms in the RDD Dictionary, and their definitions are all
found in the alphabetical listing in Clause 5.4 (Table 2). Definitions of Terms which are relied upon in the Standard
but are not StandardizedTerms are listed in this Clause.
Definitions for terms presented in this International Standard with initial Capitals and otherwise in lower case (for
example, Act, AdoptedTerm) are given in Clause 3 or in Clause 5.4 (Table 2).

The notation and modelling conventions used in this part of ISO/IEC 21000 are specific to, and exist for the
purpose of, this Standard only. This refers to the notation used in the presentation of Relationships (as explained in
A.10 and used in Clause 5.4 and Annexes A and D), the diagrammatic presentations of the Term-Attribute
relationships in Figure A.2, and the entity relation models in Figures A.6 and A.7.
5 Rights Data Dictionary
5.1 Preamble (Informative)
The StandardizedTerms in this Clause are specifically defined to support the REL as defined in ISO/IEC 21000-5
and provide the foundation of the RDD Dictionary. New Terms, developed specifically to support REL requirements,
independently or from mappings from other schemes, can be added to the RDD Dictionary through the registration
of such Terms with the Registration Authority, requirements for which are described in Annex C. Once new Terms
have been added to the RDD Dictionary, they may be used explicitly in REL expressions, or they may be translated
into appropriate REL expressions through the process of mapping described in the methodology in Annex A. The
process is therefore flexible, capable both of supporting the REL directly and of providing a means by which it can
be supported in future by the addition of Terms from external schemes, thus providing for interoperability between
different Authorities.
Great care should be taken in the use of RDD Dictionary Terms in any specific environment or application in order
to avoid unintended consequences. As a closed ontology, all RDD Dictionary Terms are defined with reference to
other RDD Dictionary Terms. This has two main consequences for the understanding of an RDD Dictionary term
when it is used in an REL license. The first is that no assumptions should be made about the meaning of a Term
based on the coincidence that it bears the same name as something in an application domain. For example, the
words “Play” and “Print” are common in applications and terminals, and they have many shades of meaning. The
RDD StandardizedTerms “Play” and “Print” mean only what they are defined to mean in this part of ISO/IEC 21000.
The RDD Dictionary meanings of “Play” and “Print” may or may not correspond to the meanings attached to the
words “play” and “print” in other domains. Words used as the names of Terms are only convenient labels: mapping
is achieved by analysis of the defined meanings of Terms, irrespective of their names.
The second consequence concerns the inheritance of meaning. As the RDD Dictionary is a hierarchical ontology,
most of the meaning of a Term is inherited from its parent(s) (in RDD Dictionary terminology, its “Archetypes”).
Because of this, if an REL license contains a Right to a StandardizedActType (for example, “Modify”), then the
holder of the license will also have all Rights for which Modify is the sole parent – that is, “Move”, “Enlarge” and
“Reduce” – even though these are not explicit in the license. On the other hand, if a term has more than one parent,
it is not wholly included in each. So, for example, if an REL license contains a Right to “Adapt”, it does not include
the Right to “Play” or “Print”, because Adapt is only one of the parents of these Terms.
5.2 Standardized ActTypes supporting REL
This table shows the fourteen ActTypes which provide the semantic content for the Multimedia Extension Rights in
Clause 9.6 of ISO/IEC 21000-5. These ActTypes provide basic functionality for the REL. Employed within a rights
expression, the Multimedia Extension Rights are capable of being used to create licences required by Rights
Holders.
The fourteen ActTypes in this part of ISO/IEC 21000 have been defined in response to requirements identified in
the process of developing the REL and RDD Standards, particularly focussed on common processes in the use
and adaptation of Digital Resources. However, it is recognised that in future further ActTypes will have to be

ISO/IEC 21000-6:2004(E)
introduced into the RDD Dictionary in response to new requirements from REL users, and either a corresponding
syntactic element may be introduced by amendment directly into the ISO/IEC 21000-5, or one of the mechanisms
described in Annex F of ISO/IEC 21000-5 or Clause 6.2 of this part of ISO/IEC 21000 to reference the new RDD
ActType may be used.
Terms in bold in Table 1 are formally defined in the RDD Dictionary.

Table 1 — Standardized ActType supporting ISO/IEC 21000-5
ActType Parent(s) Definition Comments
Adapt Derive, To ChangeTransiently an existing With Adapt, two distinct Resources will exist as a
Resource to Derive a new result of the process, one of which is the original
ChangeTran
Resource. Resource in unchanged form, and one of which is
siently
newly made. Changes can include the addition to and

removal of elements of the original Resource,
including the Embedding of other Resources.
Changes can be made temporarily to the original
resource in the course of the Adapt process, but such
changes are not saved in the original Resource at the
end of the process.
Specializations of Adapt can be differentiated by
specific attributes of the Resource which are
preserved or changed. The specific attributes can be
on a list or can be called out by using a list. Lists can
be inclusive (for example, “Attributes a and b must be
changed”) or exclusive (for example, “Everything
except attributes c and d must be changed”).
Attributes that are not constrained in specializations
can be changed.
Most ActTypes that are generally known as “copying”
may be represented in the RDD Dictionary as children
of Adapt. In most domains “copy” typically means to
Derive a new Resource which has the same set of
specified or implied attributes as its Source, a
common example being the “copying” of a Digital
Object. However, the concept of “sameness” is not to
be confused with that of identity, as two things cannot
technically be “identical” because at the very least
they will have different spatial or temporal attributes
(that is, they will be located in a different place, or
created at a different time), and so a “copy” with
absolutely identical attributes to the original cannot
logically exist. Particular interpretations of “copy” can
be defined as specializations of Adapt [for further
explanation see Annex D].
Delete Destroy To Destroy a DigitalResource. Delete applies only to DigitalResources. Delete is
not capable of reversal. After a Delete process, an
“undelete” action is impossible.
