Geographic information. Place Identifier (PI) architecture. | Status: Under review, Current

1 Scope This International Standard specifies an architecture that defines a reference model with an encoding method for an identifier of a place. The concept of “place” within this International Standard 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 this International Standard, 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 serviceinterfaces are also defined in this reference model. This International Standard 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. This International Standard is not about producing any kind of specific place description, nor about defining a unique, standardized description of defined places, such as an address coding scheme.
