5、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 techni
6、cal 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
7、 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 Intern
8、ational 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 o
9、f 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 24800-5 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 29, Coding of audio, picture,
10、 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
11、for metadata embedded in image data (JPEG and JPEG 2000) Part 5: Data interchange format between image repositories Part 6: Reference software ISO/IEC 24800-5:2011(E) ISO/IEC 2011 All rights reserved vIntroduction ISO/IEC 24800 was developed to be an interoperable mechanism to handle metadata among
12、compliant systems, including repository, search engine, and file entities. This part of ISO/IEC 24800 aims at a format for the exchange of image collections and respective metadata between JPSearch compliant repositories. It enables the synchronization of repositories in order to facilitate simple a
13、nd fully interoperable exchanges across different devices and platforms. INTERNATIONAL STANDARD ISO/IEC 24800-5:2011(E) ISO/IEC 2011 All rights reserved 1Information technology JPSearch Part 5: Data interchange format between image repositories 1 Scope This part of ISO/IEC 24800, JPSearch, provides
14、a data interchange format for the exchange of image collections and respective metadata between JPSearch compliant repositories. The metadata can be at the level of the image or an image collection. By providing a solution for the carriage of image collections and associated metadata between complia
15、nt devices and platforms, the JPSearch data interchange format enables the synchronization of repositories in order to facilitate simple and fully interoperable exchanges across different devices and platforms. The JPSearch data interchange format should enable the easy and reliable transfer of data
16、 between different hardware and software systems. In particular, it should support functions such as exchange of data between JPSearch repositories on different devices and platforms, consolidation of metadata generated on different systems, transferral of data to a newer and better system, consolid
17、ation of selected data to a centralized repository, and archive of data in a format which will survive current products. 2 Normative references The following referenced documents are indispensable for the application of this document.

25、ile format for collection-level and item-level metadata encapsulates all the collection-level and item-level metadata into a valid XML descriptor in a single text-based format. The aim is to enable easy exchange of metadata between repositories. In this case, the collection-level and item-level meta
26、data should follow the interchange format schema as defined in 7.3. Besides a plain-text XML representation, in this case the descriptive metadata can optionally be stored using BiM. 6 Resource Only JPEG-conforming, JPEG 2000-conforming and JPSearch-conforming code-streams may be used as internal or
27、 external resources in the JPSearch data interchange file format. Internal JPEG and/or JPEG 2000 and/or JPSearch Part 4 resources shall be stored in InlineMedia of ImageDataType. Alternatively, external JPEG and/or JPEG 2000 and/or JPSearch Part 4 resources can be identified by MediaUri or ImageData
28、Type. As a special case, a file can have all images defined as external resources. As a result, the file only contains metadata (collection-level and item-level). 7 Schema and metadata 7.1 General This Clause specifies the metadata which is supported by the JPSearch data interchange format. 7.2 JPSe
