BS ISO 19136-2:2015地理标记语言（GML）是一种符合ISO 19118标准的XML编码 根据概念建模进行建模的地理信息的传输和存储 ISO 19100系列国际标准中使用的框架，包括空间和 地理特征的非空间属性。ISO 19136的这一部分定义了XML模式语法、机制和约定:为地理空间应用程序模式的描述提供了一个开放的、与供应商无关的框架 用于以XML格式传输和存储地理信息；允许配置文件支持GML框架描述功能的适当子集；支持特定领域和应用程序的地理空间应用程序模式描述 信息社区；支持创建和维护链接的地理应用程序模式和数据集； 支持应用程序模式和数据集的存储和传输；提高组织共享地理应用程序模式和信息的能力 他们描述。实现者可以决定在GML中存储地理应用程序模式和信息，或者 可能会决定根据需要从其他存储格式转换，并仅将GML用于模式和 数据传输。ISO 19136的这一部分建立在ISO 19136:2007（GML 3.2）的基础上，并通过附加模式对其进行了扩展 组件和要求。注意:如果使用UML中描述的符合ISO 19109的应用程序模式作为存储的基础 ISO 19136的这一部分为地图绘制提供了规范性规则 这样的应用程序模式可以转换为XML模式中的GML应用程序模式，也可以转换为数据的XML编码 具有符合ISO 19109标准的应用程序模式的逻辑结构。 交叉引用:ISO 19136:2007ISO 19148:2012ISO 8601:2004ISO/IEC 13249-3:2011ISO 14825:2011ISO 19107:2003ISO 19108:2002ISO 19109:2005ISO 19111:2007ISO 19118:2011ISO 19123:2005ISO 19125-1:2004ISO 19133:2005ISO/TS 19103:2005购买本文件时提供的所有当前修订版均包含在购买本中。

BS ISO 19136-2:2015 The Geography Markup Language (GML) is an XML encoding in compliance with ISO 19118 for the transport and storage of geographic information modelled in accordance with the conceptual modelling framework used in the ISO 19100- series of International Standards and including both the spatial and non-spatial properties of geographic features.This part of ISO 19136 defines the XML Schema syntax, mechanisms and conventions that:provide an open, vendor-neutral framework for the description of geospatial application schemas for the transport and storage of geographic information in XML;allow profiles that support proper subsets of GML framework descriptive capabilities;support the description of geospatial application schemas for specialized domains and information communities;enable the creation and maintenance of linked geographic application schemas and datasets;support the storage and transport of application schemas and datasets;increase the ability of organizations to share geographic application schemas and the information they describe.Implementers may decide to store geographic application schemas and information in GML, or they may decide to convert from some other storage format on demand and use GML only for schema and data transport.This part of ISO 19136 builds on ISO 19136:2007 (GML 3.2), and extends it with additional schema components and requirements.NOTE If an ISO 19109 conformant application schema described in UML is used as the basis for the storage and transportation of geographic information, this part of ISO 19136 provides normative rules for the mapping of such an application schema to a GML application schema in XML Schema and, as such, to an XML encoding for data with a logical structure in accordance with the ISO 19109 conformant application schema.Cross References:ISO 19136:2007ISO 19148:2012ISO 8601:2004ISO/IEC 13249-3:2011ISO 14825:2011ISO 19107:2003ISO 19108:2002ISO 19109:2005ISO 19111:2007ISO 19118:2011ISO 19123:2005ISO 19125-1:2004ISO 19133:2005ISO/TS 19103:2005All current amendments available at time of purchase are included with the purchase of this document.
