This document defines the following three mechanisms for linking Place Identifiers (PIs) (see ISO 19155 ) to features or objects existing in other encodings:<\/p>\n
Id attribute of a GML object (gml:id) as defined in ISO 19136 ;<\/p>\n<\/li>\n
Universally Unique Identifier (UUID) as defined in IETF RFC 4122 ;<\/p>\n<\/li>\n
Uniform Resource Locator (URL) as defined in IETF RFC 1738 .<\/p>\n<\/li>\n<\/ul>\n
These PI linking mechanisms are enabled using xlink:href as defined in W3C XML Linking Language (XLink).<\/p>\n
While the identifiers of these features or objects can sometimes identify a place, within the scope of this document, the identifiers of features or objects existing in other encoding domains are referred to conceptually as other identifiers.<\/p>\n
This document further defines that when PIs are encoded, as specified in ISO 19155 , using the Geography Markup Language (GML) ( ISO 19136 ), they are linked using gml:id to other GML encoded features. The details of encoding GML instances using gml:id are specified in a normative annex.<\/p>\n
Additional normative annexes define encodings for linking Place Identifiers to other identifiers using UUID and URL and present examples for their use.<\/p>\n
This document is applicable to location-based services, linked open data, robotic assisted services and other application domains that require a relationship between PIs and objects in either the real or virtual world.<\/p>\n
This document is not about creating a registry of Place Identifiers linked to specific features or objects, and support of linking mechanisms other than gml:id, UUID, and URL is out of the scope of this document.<\/p>\n
