标准范围

ISO 19155:2012规定了一种体系结构，该体系结构定义了一个参考模型，其中包含一个地方标识符的编码方法。ISO 19155:2012中的“场所”概念不仅包括现实世界中的“场所”，还包括虚拟世界中的“场所”。使用坐标标识符、地理标识符或虚拟世界标识符（如URI）来标识这些“位置”。在ISO 19155:2012中，一个地点的标识符被称为地点标识符（PI）。参考模型定义了一种机制，将多个地点标识符与同一地点相匹配。此外，该参考模型还定义了一个数据结构和一组服务接口。ISO 19155:2012适用于基于位置的服务、应急管理服务和其他应用领域，这些领域需要一个跨特定领域的通用体系结构，以使用坐标、地理或虚拟世界标识符表示位置描述。

ISO 19155:2012 specifies an architecture that defines a reference model with an encoding method for an identifier of a place. The concept of "place" within ISO 19155:2012 includes "places" not only in the real world but also those in the virtual world. These "places" are identified using either coordinate identifiers, geographic identifiers, or virtual world identifiers such as URI. In ISO 19155:2012, an identifier of a place is referred to as a Place Identifier (PI).The reference model defines a mechanism to match multiple Place Identifiers to the same place. In addition, a data structure and set of service interfaces are also defined in this reference model.ISO 19155:2012 is applicable to location based services, emergency management services and other application domains that require a common architecture, across specific domains, for the representation of place descriptions using coordinate, geographic, or virtual world identifiers.
