Internet Engineering Task Force (IETF) M. Thomson Request for Comments: 7035 Microsoft Category: Standards Track B. Rosen ISSN: 2070-1721 Neustar D. Stanley Aruba Networks G. Bajko Nokia A. Thomson Lookingglass October 2013 Relative Location Representation Abstract This document defines an extension to the Presence Information Data Format Location Object (PIDF-LO) (RFC 4119) for the expression of location information that is defined relative to a reference point. The reference point may be expressed as a geodetic or civic location, and the relative offset may be one of several shapes. An alternative binary representation is described. Optionally, a reference to a secondary document (such as a map image) can be included, along with the relationship of the map coordinate system to the reference/offset coordinate system, to allow display of the map with the reference point and the relative offset.
