Internet Engineering Task Force (IETF) J. Winterbottom Request for Comments: 6753 Commscope Category: Standards Track H. Tschofenig ISSN: 2070-1721 Nokia Siemens Networks H. Schulzrinne Columbia University M. Thomson Microsoft October 2012 A Location Dereference Protocol Using HTTP-Enabled Location Delivery (HELD) Abstract This document describes how to use the Hypertext Transfer Protocol (HTTP) over Transport Layer Security (TLS) as a dereference protocol to resolve a reference to a Presence Information Data Format Location Object (PIDF-LO). This document assumes that a Location Recipient possesses a URI that can be used in conjunction with the HTTP-Enabled Location Delivery (HELD) protocol to request the location of the Target. 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.

Introduction A location URI [RFC5808] identifies a resource that contains the location of an entity. This document specifies how a holder of an "http:" or "https:" location URI uses that URI to retrieve location information using a subset of HELD functionality or an HTTP GET request. A location URI can be acquired using a location configuration protocol, such as HTTP-Enabled Location Delivery (HELD) [RFC5985] or the Dynamic Host Configuration Protocol (DHCP) location URI option [DHCP-URI-OPT]. A Location Recipient that dereferences a location URI acquires location information in the form of a Presence Information Data Format - Location Object (PIDF-LO) document [RFC4119]. HELD parameters allow for specifying the type of location information,Show full document text
