标准摘要
[中文适用范围]: 本文件定义了通用特征模型(GFM)作为用于创建地理信息建模中应用模式的元模型。GFM被解释并实施为创建和记录应用模式的规则,包括特征定义的原则。本文件适用于以下方面: — 从一个讨论领域中对特征及其属性进行概念建模; — 定义应用模式; — 使用概念模式语言创建应用模式的一般规则; — 使用UML作为概念模式语言的应用模式规则; — 从概念模型中的概念向应用模式中的数据类型进行转换; — 将其他ISO地理信息标准中的标准化模式与应用模式进行集成。 本文件不适用于以下方面: — 为应用模式选择特定的概念模式语言; — 定义任何特定的应用模式; — 在特征目录中表示特征类型及其属性; — 表示元数据; — 将一种应用模式映射到另一种应用模式的规则; — 在计算机环境中实现应用模式; — 计算机系统和应用软件设计; — 编程。 [外文原描述]: This document defines the General Feature Model (GFM) as the metamodel for creating application schemas in the context of geo-information modelling. The GFM is explained and implemented as rules for creating and documenting application schemas, including principles for the definition of features. This document is applicable to: — conceptual modelling of features and their properties from a universe of discourse; — definition of application schemas; — general rules for using a conceptual schema language for application schemas; — rules for application schemas using UML as the conceptual schema language; — transition from the concepts in the conceptual model to the data types in the application schema; — integration of standardized schemas from other ISO geographic information standards with the application schema. This document does not apply to: — choice of one particular conceptual schema language for application schemas; — definition of any particular application schemas; — representation of feature types and their properties in a feature catalogue; — representation of metadata; — rules for mapping one application schema to another; — implementation of the application schema in a computer environment; — computer system and application software design; — programming.
