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.

Claims (80)

1. A method of tying a geospatial location to a PIDF-LO file, comprising:

receiving, at a physical network server, a Presence Information Data Format-Location Object (PIDF-LO) file;

determining, at said physical network server, that said PIDF-LO file lacks geospatial location information identifying a specific physical zone;

identifying a universal resource locator (URL) of XML content relating to a location relevant to said PIDF-LO compliant file;

requesting said geospatial location information, through said physical network server;

associating, at said physical network server, said geospatial location information with said XML content; and

inserting, at said physical network server, said URL of XML content into said PIDF-LO file.

2. The method of tying a geospatial location to a PIDF-LO file according to claim 1 , wherein:

said URL of XML content is inserted in an “entity=” list in said <presence . . . > section of said PIDF-LO file.

3. The method of tying a geospatial location to a PIDF-LO file according to claim 2 , wherein:

said URL of XML content is also inserted in a “src=” list in said <presence . . . > section of said PIDF-LO file.

4. The method of tying a geospatial location to a PIDF-LO file according to claim 1 , wherein:

said URL of XML content is inserted in a “name=” list in said <presence . . . > section of said PIDF-LO file.

5. The method of tying a geospatial location to a PIDF-LO file according to claim 1 , wherein:

said geospatial location information is defined using a coordinate based polygon system.

6. The method of tying a geospatial location to a PIDF-LO file according to claim 5 , wherein:

said coordinate based polygon system is defined using an assigned numbering system.

7. The method of tying a geospatial location to a PIDF-LO file according to claim 1 , wherein:

said geospatial location information identifies a specific latitude/longitude.

8. The method of tying a geospatial location to a PIDF-LO file according to claim 1 , wherein:

said geospatial location information is defined directionally.

9. The method of tying a geospatial location to a PIDF-LO file according to claim 1 , wherein:

said XML content comprises text.

10. The method of tying a geospatial location to a PIDF-LO file according to claim 1 , wherein:

said XML content comprises images.

11. The method of tying a geospatial location to a PIDF-LO file according to claim 1 , wherein:

said XML content comprises audio.

12. The method of tying a geospatial location to a PIDF-LO file according to claim 1 , wherein:

said XML content comprises video.

13. The method of tying a geospatial location to a PIDF-LO file according to claim 1 , wherein:

said XML content is Multimedia Internet Message Extensions (MIME) type content.

14. The method of tying a geospatial location to a PIDF-LO file according to claim 1 , further comprising:

tagging descriptive information relating to said location aware XML content in a <presence . . . > section of said PIDF-LO file.

15. The method of tying a geospatial location to a PIDF-LO file according to claim 14 , wherein:

said tagged descriptive information is included in said <presence . . . > section of said PIDF-LO file.

16. The method of tying a geospatial location to a PIDF-LO file according to claim 14 , wherein:

said tagged descriptive information includes at least one of: “weather”, “century”, “season”, and “year” tags.

17. The method of tying a geospatial location to a PIDF-LO file according to claim 14 , wherein:

said tagged descriptive information includes at least one of: “Time Reference”, “Weather Reference”, and “Descriptive Reference” tags.

18. A method of tying a geospatial location to a PIDF-LO file, comprising:

receiving, at a physical network server, a Presence Information Data Format-Location Object (PIDF-LO) file;

determining, at said physical network server, that said PIDF-LO file lacks geospatial location information identifying a specific physical zone;

identifying a universal resource locator (URL) of XML content relating to a location relevant to said PIDF-LO file;

requesting, through said physical network server, said geospatial location information;

associating, via a Session Initiation Protocol (SIP) protocol, said geospatial location information with said XML content; and

inserting, at said physical network server, said URL of XML content into said PIDF-LO file.

19. The method of tying a geospatial location to a PIDF-LO file according to claim 18 , wherein:

said URL of XML content is inserted in an “entity=” list in said <presence . . . > section of said PIDF-LO file.

20. The method of tying a geospatial location to a PIDF-LO file according to claim 19 , wherein:

said URL of XML content is also inserted in a “src=” list in said <presence . . . > section of said PIDF-LO file.

21. The method of tying a geospatial location to a PIDF-LO file according to claim 18 , wherein:

said URL of XML content is inserted in a “src=” list in said <presence . . . > section of said PIDF-LO file.

22. The method of tying a geospatial location to a PIDF-LO file according to claim 18 , wherein:

said URL of XML content is inserted in a “name=” list in said <presence . . . > section of said PIDF-LO file.

23. The method of tying a geospatial location to a PIDF-LO file according to claim 18 , wherein:

said geospatial location information is defined using a coordinate based polygon system.

24. The method of tying a geospatial location to a PIDF-LO file according to claim 23 , wherein:

said coordinate based polygon system is defined using an assigned numbering system.

25. The method of tying a geospatial location to a PIDF-LO file according to claim 18 , wherein:

said geospatial location information identifies a specific latitude/longitude.

26. The method of tying a geospatial location to a PIDF-LO file according to claim 18 , wherein:

said geospatial location information is defined directionally.
