Abstract
The format of the Presence Information Data Format-Location Object (PIDF-LO) as defined by the Internet Engineering Task Force (IETF) is extended or modified to accommodate, within the standard PIDF-LO format, an association of geospacial location to XML content on the Internet. A geospacial location is associated with Extensible Markup Language (XML) content on the Internet. The XML content is identified by a universal resource locator (URL), and associated with geospatial location information (either a specific location, zone, or direction). The URL is inserted into a <presence . . . > section of a Presence Information Data Format-Location Object (PIDF-LO) compliant document as defined by the Internet Engineering Task Force (IETF). In this way, geospacial location information is associated with Internet based XML content using a standard PIDF-LO format.
