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. Status of This Memo This is an Internet Standards Track document. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Further information on Internet Standards is available in Section 2 of RFC 5741.

Novel Coronavirus: A Review from Origin to Current Status of Therapeutic Strategies

“…NVX-CoV2373 is a full-length SARS-COV-2 protein subunit vaccine that was developed by Novavax (Gaithersburg, MD) and carries a mutated S1/S2 cleavage site to resist proteolytic degradation. 75 Its molecular conformation is almost identical to the natural protein, with a slight difference in its S1 subunit and normal binding ability between the spike trimers. This vaccine is formulated, before injection, with saponin-based adjuvant Matrix-M to enhance its immunogenicity.…”

The Application of Telematics and Smart Devices in Emergencies: Use Cases in Next Generation Emergency Services

“…Where a "one off" data is involved (no human communication), data is sent without initialising a SIP session by using the SIP MESSAGE transaction as recommended in [3]. Data structures and mechanisms will follow work in [4], which includes: location (conveyed in the Presence Information Data Format Location Object (PIDF-LO) [5][6][7][8][9]), call related information (device type (including sensor type), service providers, subscriber (including personal information), contact information) and caller information (medical information and "in case of emergency" (ICE) contact data).…”

Additional Data Related to an Emergency Call

“…Data Associated with a Location: Primary location data is conveyed in the Presence Information Data Format Location Object (PIDF-LO) data structure as defined in RFC 4119 [RFC4119] and extended by RFC 5139 [RFC5139] and RFC 6848 [RFC6848] (for civic location information), RFC 5491 [RFC5491] and RFC 5962 [RFC5962] (for geodetic location information), and RFC 7035 [RFC7035] (for relative location). This primary location data identifies the location or estimated location of the caller.…”
