标准范围

ISO/IEC 24800-3:20 10，也称为“JPSearch查询格式（JPQF）”，作为ISO/IEC 15938-12:20 08对图像和伴随元数据的专门化，在输入查询格式、输出结果格式和查询管理三个方面为图像搜索和检索系统提供了标准化接口。ISO/IEC 24800-3:20 10中定义的顶级工具是InputQuery、FetchResult、OutputResult和Management。InputQuery和FetchResult工具都属于输入查询格式。除了描述通过InputQuery返回的结果集的一组优选输出参数之外，输入查询格式还为用户/系统提供了一组精确的输入参数来描述他们的搜索标准。通过InputQuery，用户可以使用各种类型的查询，如按媒体查询、按描述查询、按自由文本查询，并使用代数或逻辑表达式组合。通过FetchResult，用户可以检索过去查询的搜索结果。当使用异步模式发出查询请求时，FetchResult元素用于指示用户接收结果的准备情况。当使用同步模式发出查询请求时，FetchResult元素用于接收结果集的各个页面（如果启用了分页）。输出结果格式OutputResult为用户/系统提供一组输出参数，以描述用于用户呈现或机器消费的聚合返回结果集。作为查询管理工具集的管理工具提供了用于基于服务属性(例如，MPEG-7数据库或核心元数据服务)或聚合服务(例如，管理一组不同服务的服务提供商)选择服务(例如，MPEG-7数据库或核心元数据服务)的装置。g.支持的查询格式，支持的元数据标准）。目标是定义一种查询语言，为行业提供一种标准化的格式来接受和响应图像搜索的用户/系统规范。在JPSearch的框架中，JPSearch查询格式被设计为用作查询客户端和应答服务器之间以及聚合服务代理和单个服务提供者之间的接口。

ISO/IEC 24800-3:2010, also known as “JPSearch Query Format (JPQF)”, provides a standardized interface for image search and retrieval systems in three aspects - input query format, output result format and query management - as a specialization of ISO/IEC 15938-12:2008 for images and accompanying metadata.

The top-level tools defined in ISO/IEC 24800-3:2010 are InputQuery, FetchResult, OutputResult and Management. Both InputQuery and FetchResult tools belong to input query format.

The input query format provides users/systems with a set of precise input parameters to describe their search criteria in addition to a set of preferred output parameters to depict the return result sets through InputQuery. Through InputQuery, users can use queries of various types, such as query by media, query by description, query by free text, and combine them using algebraic or logical expressions. Through FetchResult, users can retrieve search results of a query from the past. When a query request is issued using the asynchronous mode, the FetchResult element is used to indicate the preparedness of the user to receive results. When a query request is issued using the synchronous mode, the FetchResult element is used to receive individual pages of the result set (if paging is activated).

The OutputResult, which is the output result format, provides users/systems with a set of output parameters to describe the aggregated return result sets for user presentation or machine consumption.

The Management tool, which is the query management tool set, provides a means for selecting services (e.g. MPEG-7 database or Core Metadata services) or aggregated services (e.g. service provider that administers a set of different services) based on service properties (e.g. supported query format, supported metadata standard).

The goal is to define a query language that provides the industry with a standardized format to accept and respond to user/system specification for image searches. In the framework of JPSearch, the JPSearch Query Format is designed to be used as an interface between querying client and answering servers, as well as between aggregation service agent and individual service providers.
