Revised Civic Location Format for Presence Information Data Format Location Object (PIDF-LO)

Dynamic Host Configuration Protocol Options for Coordinate-Based Location Configuration Information

“…If the Altitude Type is 2 (floors), then this value can be represented using a civic address object [RFC5139] that is presented alongside the geodetic object.…”

Specifying Civic Address Extensions in the Presence Information Data Format Location Object (PIDF-LO)

“…The Geopriv civic location specifications ( [RFC4776], [RFC5139]) define an XML and binary representations for civic addresses that allow for the expression of civic addresses. Guidance for the use of these formats for the civic addresses in different countries is included in [RFC5774].…”

“…[RFC5774] describes a mechanism for mapping long-standing address formats into the civic address elements defined in [RFC4776] and [RFC5139]. However, some of these existing address elements do not readily fit into the civic address elements defined in [RFC4776] and [RFC5139].…”

“…However, some of these existing address elements do not readily fit into the civic address elements defined in [RFC4776] and [RFC5139]. In these cases, creating new civic address elements provides a better solution than overloading existing civic address fields, which may cause confusion.…”

“…The XML format for civic addresses [RFC5139] provides a mechanism that allows for the addition of standardized or privately understood elements. A similar facility for private extension is not provided for the DHCP format [RFC4776], though new specifications are able to define new CAtypes (civic address types).…”
