10、tional 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 fiel

11、ds 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 j

12、oint 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 commit

13、tee 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

14、 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,

15、 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 form

16、at between image repositories Part 6: Reference software ISO/IEC 24800-2:2011(E) vi ISO/IEC 2011 All rights reservedIntroduction This part of ISO/IEC 24800 provides a standardized set of technologies for metadata representation, querying and management of images. It specifies the JPSearchs Core Meta

17、data 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

18、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 proprietar

19、y 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, thi

20、s 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. Managemen

21、t of information regarding other metadata schema is also described in respect of registration, maintenance, and translation rules.

22、chema and ontology 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 fo

23、r 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 Metadat

24、a 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 24

28、and definitions apply. ISO/IEC 24800-2:2011(E) 2 ISO/IEC 2011 All rights reserved3.1 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 reque

29、sts 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 JPSearc

30、hs 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

31、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 metad

32、ata 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 capitali

33、zed, with the exception that the capitalization of the first word depends on the type of construct and is described below. Element naming: the first letter of the first word is capitalized (e.g. Identifier element of JPSearchCoreType). Attribute naming: the first letter of the first word is not capi

34、talized (e.g. jpsearchID attribute of ManagementType type). 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). simpleType naming: the first letter of the first word is not capitalized, the suffix “Type“

35、 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

36、in the following example: ISO/IEC 24800-2:2011(E) ISO/IEC 2011 All rights reserved 3The 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 E

37、xampleType 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

38、: 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

39、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 author

40、ities 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, Publish

41、erType and JPSearchCoreType. Moreover, in order to support JPSearchCoreType, several types are defined: RightsDescriptionType, PlaceType, PersonType, OrganizationType, EventType, ObjectType, RegionOfInterestType, RegionLocatorType, ExternalDescriptionType, ControlledRatingTermType, ImageIdentifierTy

42、pe 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 het

43、erogeneous metadata schemes, JPSearchCoreType contains the most important fields in JPSearch core metadata.
