ISO/IEC 21000-19:2010 describes MPEG-21 Media Value Chain Ontology (MVCO). The MVCO may be used to capture knowledge about media value chains and to represent it in a computer readable way, concepts in the domain and the relationships between those concepts. ISO/IEC 21000-19:2010 describes the following technology. Model: the model is described in Clause 6, by way of a narrative description of the Value Chain, its main elements and relations. Representation: the MVCO has been formalised as a normative OWL Ontology, and the description of which is given in this Clause. The description consists of listing the classes, the object properties, the datatype properties, and the class individuals. Classes are described by giving the name, an English definition, the class hierarchy, and the restrictions imposed on the class. The representation is given in Clause 7. Annex B contains the normative OWL (XML/RDF) comprising the entire semantics of the elements in the model. Ontology use: an Informative section is provided with non normative descriptions of use, extensions and an API (Annex A).

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 21000-19 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,

Introduction
Today, many elements exist to build an infrastructure for the delivery and consumption of multimedia content.
There was, however, no “big picture” to describe how these elements, either in existence or under
development, relate to each other. The aim for the set of standards ISO/IEC 21000 has been to describe how
these various elements fit together. New standards as appropriate will be developed while other relevant
standards may be developed by other 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 ISO/IEC 21000-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
ISO/IEC 21000 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 part of ISO/IEC 21000 specifies a machine readable ontology of the media value chain defining a minimal
set of kinds of intellectual property, the roles of the users interacting with them, and the relevant actions
regarding intellectual property among other features.

Part 19:
Media Value Chain Ontology
1 Scope
This Part of ISO/IEC 21000 describes MPEG-21 Media Value Chain Ontology (MVCO). The MVCO may be
used to capture knowledge about media value chains and to represent, in a computer readable way, concepts
in the domain and the relationships between those concepts.
This Part of ISO/IEC 21000 consists of seven Clauses and two Annexes. This technology is described in the
following sections of this Part of ISO/IEC 21000.
⎯ Model:
the model is described in Clause 6, by way of a narrative description of the Value Chain, its main
elements and relations.
⎯ Representation:
the MVCO has been formalised as a normative OWL Ontology, and the description of which is given in
this Clause. The description consists of listing the classes, the object properties, the datatype properties,
and the class individuals. Classes are described by giving the name, an English definition, the class
hierarchy, and the restrictions imposed on the class. The representation is given in Clause 7. Annex B
contains the normative OWL (XML/RDF) comprising the entire semantics of the elements in the model.
⎯ Ontology use:
an Informative section is provided with non normative descriptions of use, extensions and an API
(Annex A).

4 Conventions
4.1 Documentation conventions
The reader is informed that terms beginning with a capital letter (like “Work”) are used according to definitions
given in Clause 3. Terms referred to in the ontology elements are given with its namespace (e.g. mvco:Work).
4.1.1 Class description
7.2.4 provides a systematic enumeration of the MVCO classes. Some conventions are explained in this
subclause. For each OWL class, the following features may be given:
− Class name. The OWL class name, given as an owl:Class in the Ontology. Class names follow the
convention of using an uppercase for the first letter, and leaving no blankspaces or dashes between
words if more words are included. Qualified names start with the ontology URI, like
http://purl.oclc.org/NET/MVCO.owl#User
− Comment. The English definition, given as a rdfs:comment in the Ontology.
− Restrictions. A set of expressions with an accompanying human explanation that must hold for an
individual to belong to the class in question. Each of these propositions is either necessary
(introduced by the symbol ⊆) or necessary and sufficient (introduced by the symbol ≡). The former is
a condition that each class individual must satisfy, and the later is a condition which, if held, is enough
to state that the individual belongs to this class. Each restriction is given as a parent class of the class
in question, and can be one of the following:
− Existential restriction (“some”). Expressed by means of the owl:someValuesFrom OWL
element and represented here by the symbol ∃, it expresses the fact that an individual of this
class must be related to at least one individual of the given Range class. This is a quantifier
restriction.
− Universal restriction (“only”). Expressed by means of the owl:allValuesFrom OWL
element and represented here by the symbol ∀, it expresses the fact that an individual of this
class can only be related to individuals of the given Range class. This is a quantifier
restriction.
− Cardinality restrictions (“min”, “max,”, “exactly”). Determine the number of relationships
that an individual of this class must participate in (by giving a minimum, a maximum or an
exact number).
− Disjoint classes restriction. Classes can be required to be disjoint (i.e., a class individual may
not be allowed to belong to two given classes at the same time.), but disjoint classes have
not been represented in the enumeration.
− In-domain-of. Object Properties for which the given class is the Domain, if any.
− Known subclasses. Graphical representation of the known subclasses, if any.

---------------------- Page: 13 ----------------------
ISO/IEC 21000-19:2010(E)
Classes can be joint with the union operator, so that (mvco:Creator ∪ mvco:Adaptor) means the set of
individuals which are either Creator or Adaptor individuals (or both). The intersection operators ∩ defines
individuals belonging to both classes. Propositions can use the operators AND, OR and NOT (¬).
4.1.2 Property description
7.4 lists all the defined relations in the ontology. For each relation the following features may be given:
− Name. The name of the relation. Properties follow the convention of including as a first word an
English verb starting with a lowercase letter, followed by subsequent words starting with an uppercase
letter and no blankspaces or dashes in between.
− Description. Description of the relation, given as an English text in the rdfs:comment element.
− Domain of the property. Limits the individuals to which the property can be applied.
− Range of the property. Limits the individuals that the property may have as its value. In datatype
properties, only literal values are accepted.
− Characteristics of the property. These give a more precise description of the relation, stating
whether the property is symmetric, transitive, functional or inverse of the other property.
Object properties are represented in Figure 1 and Figure 3 of this document following this convention:
− Arcs represent object properties, the name of which is next to its head. The cardinality is given next to
its tail, indicating how many class individuals can be related to one individual. For example, 1.n
indicates that one individual can be linked with this property with one or more individuals.
− Source nodes are the domain of the object property.
− Sink nodes are the range of the object property.
4.2 Namespace prefix conventions
MVCO includes an initial rdf:RDF component with some XML namespace declarations. Namespaces provide
a means to unambiguously interpret identifiers and make the rest of the ontology presentation much more
readable. It also contains the base URI for this document and the default namespace, which has been chosen
as the URI of the document containing the ontology.
The ontology URI shall be http://purl.oclc.org/NET/mvco.owl. This is a permanent URI deemed to
provide a permanent reference regardless of the actual location of the MVCO ontology. The following
namespace conventions have been adopted:

5 Relationship to other ISO/IEC 21000 Parts
The Digital Item is the fundamental unit of distribution and transaction in the Multimedia framework. While the
different parts of ISO/IEC 21000 deal with the components and different aspects of Digital Items, together they
form a complete integrated interoperable framework. This Clause describes the relationship of this part of
ISO/IEC 21000 with other parts of ISO/IEC 21000 in addressing the Intellectual Property (IP) represented by
Digital Items and their elements as well as how such IP is subsequently handled by Users.
The MVCO represents a model integrating different elements of the ISO/IEC 21000 interoperable framework.
MVCO defines different types of objects subject to intellectual property; these IP Entities are represented
through Digital Items or parts thereof defined in ISO/IEC 21000-2. IP Entities represented as MVCO IP Entity
class instances are identified with the Digital Item Identifiers as described in ISO/IEC 21000-3. MVCO User
class instances refer to Users as conceived in ISO/IEC 21000-1.
Furthermore, MVCO based applications makes use of ISO/IEC 21000-15 (Event Reporting), e.g. events in
MVCO trigger Event Reports (ISO/IEC 21000-15), and ISO/IEC 21000-5 (Rights Expression Language), e.g.
to express permissions.
Also, ISO/IEC 21000-6 Rights Data Dictionary (RDD) and MVCO are complementary within the MPEG-21
Framework and their vocabularies may be jointly used within MVCO based applications according to users
needs. Many relationships between the elements in these two standards may be established without logical
contradictions or interpretative ambiguities.
6 Media Value Chain Model
6.1 Introduction
This Clause is intended to facilitate a high level understanding of the MVCO core model. Although all aspects
referenced are normative, the complete formal description is given in Clause 7 of this document.
The Media Value Chain Ontology is designed to represent common aspects of content creation, distribution,
use and handling. Central to this is the need to adhere to basic common notions related to Intellectual
Property.
6.2 Fundamentals of Intellectual Property
Any notion of Intellectual Property implies the existence of a minimum and necessary set of entities, roles,
rights and actions, each a corollary of the other. The objective and scope of the MVCO is to represent a
minimum set in a machine readable fashion either directly in a core model or through appropriate extensions.
While there are clear differences in the legal treatment of IP between different jurisdictions, this does not
mean that a common core between them does not exist. The existence of such a core is reflected by the
1)
numerous International World Intellectual Property Organization (WIPO ) treaties such as the Berne
Convention where if it were not for a clear understanding of common terms such as work, adaptation,
1) The World Intellectual Property Organization (WIPO) defines Intellectual Property as the creations of the mind:
inventions, literary and artistic works, and symbols, names, images, and designs used in commerce.

performance etc., it would not be possible for such a treaty to be assumed by 163 different national
jurisdictions. Presently, this common IP model lacks a standard computer representation that the MVCO
provides.
The kind of IP Entity represented by a Digital Item will be specified in the context of the MVCO, so that it is
possible that the same bits of a Digital Item may represent different kinds of IP (e.g., a Manifestation or
Product).
6.3 Description of the IP Entity relations within the Value Chain
As far as IP Entities are concerned, and for each IP Entity, Users have Roles associated to them (Creator,
Adaptor, Instantiator, Producer.) that represent
