GEOPRIV Presence Information Data Format Location Object (PIDF-LO) Usage Clarification, Considerations, and Recommendations

摘要: The Presence Information Data Format Location Object (PIDF-LO) specification provides a flexible and versatile means to represent location information. There are, however, circumstances that arise when information needs be constrained in how it is represented. In these circumstances, the range of options need implemented are reduced. growing interest being able use location information contained PIDF-LO for routing applications. To allow successful interoperability between applications, location information needs normative more tightly than currently specified RFC 4119 (PIDF-LO). This document makes recommendations on constrain, represent, interpret locations PIDF-LO. It further recommends subset Geography Markup Language (GML) 3.1.1 mandatory implement by applications involved in location-based routing. [STANDARDS-TRACK]
