标准范围

地理标记语言（GML）是一种符合ISO 19118的XML编码，用于传输和存储根据ISO 19100系列国际标准中使用的概念建模框架建模的地理信息，包括地理特征的空间和非空间属性。ISO 19136:2007定义了XML模式语法、机制和约定:提供一个开放的、供应商中立的框架，用于描述以XML传输和存储地理信息的地理空间应用模式；允许支持GML框架描述能力的适当子集的配置文件；支持专门领域和信息社区的地理空间应用模式描述；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及其描述的信息的能力。实现者可能决定将地理应用程序模式和信息存储在GML中，或者他们可能决定按需从某种其他存储格式进行转换，并将GML仅用于模式和数据传输。注意:如果在UML中描述的符合ISO 19109的应用模式被用作存储和传输地理信息的基础，ISO 19136提供了将这种应用模式映射到XML模式中的GML应用模式的规范性规则，并且因此映射到具有符合ISO 19109的应用模式的逻辑结构的数据的XML编码。

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.ISO 19136:2007 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 data sets;
• 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.NOTE If an ISO 19109 conformant application schema described in UML is used as the basis for the storage and transportation of geographic information, 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.
