Projekta Nr.ISO 19155-2:2017
Nosaukums<p>ISO 19155-2:2017 defines the following three mechanisms for linking Place Identifiers (PIs) (see ISO 19155) to features or objects existing in other encodings:</p> <p>- Id attribute of a GML object (gml:id) as defined in ISO 19136;</p> <p>- Universally Unique Identifier (UUID) as defined in IETF RFC 4122;</p> <p>- Uniform Resource Locator (URL) as defined in IETF RFC 1738.</p> <p>These PI linking mechanisms are enabled using xlink:href as defined in W3C XML Linking Language (XLink).</p> <p>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> <p>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> <p>Additional normative annexes define encodings for linking Place Identifiers to other identifiers using UUID and URL and present examples for their use.</p> <p>ISO 19155-2:2017 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> <p>ISO 19155-2:2017 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>
