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 24800-2 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 24800 consists of the following parts, under the general title Information technology — JPSearch:
⎯ Part 1: System framework and components
⎯ Part 2: Registration, identification and management of schema and ontology
⎯ Part 3: Query format
⎯ Part 4: File format for metadata embedded in image data (JPEG and JPEG 2000)
⎯ Part 5: Data interchange format between image repositories
⎯ Part 6: Reference software

Introduction
This part of ISO/IEC 24800 provides a standardized set of technologies for metadata representation, querying
and management of images. It specifies the JPSearch’s Core Metadata Schema as the cornerstone of
metadata interoperability in ISO/IEC 24800. It also specifies the structure and rules to which any metadata
annotation of images must conform in order to be considered valid within a JPSearch compliant system.
In addition to the definition of JPSearch Core Metadata Schema, ISO/IEC 24800 provides a mechanism which
allows a JPSearch compliant system taking profit from proprietary or community-specific metadata schemas.
A translation rules language is defined, allowing the publication of machine-readable translations between
metadata terms belonging to proprietary metadata schemas and metadata terms in the JPSearch Core
Metadata Schema. Users can choose which metadata language to use in a JPSearch-based interaction
(annotation, querying, etc.) if the proper translations are available.
In order to specify the issues in a detailed manner in this document, this part of ISO/IEC 24800 first provides
the fundamental information including scope definition, description of terms and definitions, and conventions
that are necessary to understand this document. The definition of JPSearch Core Metadata Schema is
described in the context of XML structure. Management of information regarding other metadata schema is
also described in respect of registration, maintenance, and translation rules.

1 Scope
This part of ISO/IEC 24800 specifies a series of interfaces to allow disparate systems an interoperable
management of image repositories. It also specifies the general rules which govern the usage of metadata in
JPSearch and provides a specification which
⎯ provides rules for the representation of image metadata descriptions, consisting of the definition of the
JPSearch Core Metadata Schema,
⎯ provides rules for the publication of machine-readable translations between metadata terms belonging to
proprietary metadata schemas and metadata terms in the JPSearch Core Metadata Schema, and
⎯ provides rules for the registration and request of metadata schemas and its translation rules or links to
them.
JPSearch is an extensible standard. The normative method of extending the structures and rules beyond the
JPSearch Core Metadata Schema is provided in this part of ISO/IEC 24800.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
© ISO/IEC 2011 – All rights reserved 1
---------------------- Page: 7 ----------------------
ISO/IEC 24800-2:2011(E)
3.1
Core schema
metadata basis supporting interoperability during search among multiple image retrieval systems
NOTE The core schema is used by clients to formulate in combination with the JPEG Query Format search requests
to JPSearch compliant search systems. Note, that only metadata described by the core schema is guaranteed to be
processed by JPSearch compliant systems.
3.2
Translation rules
machine-readable declaration of the semantic and syntactic mappings between a proprietary metadata
schema and the JPSearch’s core metadata schema
3.3
JPSearch registration authority
Organization that supports the registration and request of metadata schemas and its translation rules or links
to them
NOTE It is necessary that every participating content provider registers their schema and translation rules or a link to
them at this authority. In case the JPSearch compliant retrieval system is operated in offline mode, the necessary
information (target schema, translation rules, etc.) should be available at the respective system itself.
4 Conventions
4.1 Naming convention
In order to specify the JPSearch Core metadata description scheme, this Part of ISO/IEC 24800 uses
constructs provided by XML such as "element" and "complexType." The names associated to these
constructs are created on the basis of the following conventions:
If the name is composed of multiple words, the first letter of each word is capitalized, with the exception that
the capitalization of the first word depends on the type of construct and is described below.
z Element naming: the first letter of the first word is capitalized (e.g. Identifier element of
JPSearchCoreType).
z Attribute naming: the first letter of the first word is not capitalized (e.g. jpsearchID attribute of
ManagementType type).
z complexType naming: the first letter of the first word is capitalized, and the suffix "Type" is used at the
end of the name (e.g. JPSearchCoreType).
z simpleType naming: the first letter of the first word is not capitalized, the suffix "Type" may be used at the
end of the name (e.g. xPathType).
4.2 Document convention
The syntax of each description is specified using the constructs provided by XML as defined in XML, XML
Schema Part 1, and XML Schema Part 2, and is presented in this document using a specific font and
background as shown in the following example:
2 © ISO/IEC 2011 – All rights reserved
---------------------- Page: 8 ----------------------
ISO/IEC 24800-2:2011(E)
The semantics of each description tool is specified in text using a table format, where each row contains the
name and a definition of a type, element or attribute as shown in the following example:
Name Definition
ExampleType Specifies an …
element1 Describes the …
attribute1 Describes the …
4.3 Wrapper of the schema
The description examples and syntax of description tools specified in this document assume that a schema
wrapper is provided which identifies the XML Schema namespace (XML Schema) and JPSearch namespace:
xmlns:JPCore="JPSearch:schema:coremetadata"
targetNamespace="JPSearch:schema:coremetadata"
elementFormDefault="qualified"
attributeFormDefault="unqualified">
The following tag is used to close the schema:
5 JPSearch Core Metadata Schema
5.1 General
This clause targets on the definition of the complex types for the registration process of the schema, its
translation rules and contact information. The process of registration is mandatory for all schemas that can be
addressed within a retrieval operation. The standard supports two scenarios. First, a global authority for
schemas and their translation rules will be established where all JPSearch compliant retrieval applications can
obtain the necessary information. The list of ISO registration authorities is listed at
http://www.iso.org/iso/maintenance_agencies. Second, in case the retrieval application operates in offline
mode, the schema and their translation rules shall be located at the application itself.
JPSearch Core Metadata Schema contains four types: PersonNameType, SourceType,
PublisherType and JPSearchCoreType. Moreover, in order to support JPSearchCoreType,
several types are defined: RightsDescriptionType, PlaceType, PersonType,
OrganizationType, EventType, ObjectType, RegionOfInterestType, RegionLocatorType,
ExternalDescriptionType, ControlledRatingTermType, ImageIdentifierType and
GPSPositionType.
5.2 JPSearchCoreType
5.2.1 Introduction
The JPSearchCoreType type is devised in order to describe the information about an image in metadata
layer. At the same time, as JPSearch core metadata is utilized for image search among the set of images that
are described by using heterogeneous metadata schemes, JPSearchCoreType contains the most
important fields in JPSearch core metadata.
