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 virtual content on the Internet. A filename of virtual content is associated with geospatial location information (either a specific location, zone, or direction). The filename 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 virtual content using a standard PIDF-LO format.

Claims

1. A method of associating a geospacial location to content on a network, comprising:

identifying, at a physical network server, geospacial location information;

identifying, at said physical network server, an Extensible Markup Language (XML) content identifier identifying XML content;

associating, at said physical network server, geospacial location information with said XML content via said XML content identifier; and

formulating, at said physical network server, Presence Information Data Format-Location Object (PIDF-LO) data including said geospacial location information associated with said XML content via said XML content identifier.

2. The method of associating a geospacial location to content on a network according to claim 1, wherein:

a filename of said XML content identifier is inserted in an “

entity=”

list in a <

presence . . . >

section of said modified PIDF-LO data.

3. The method of associating a geospacial location to content on a network according to claim 2, wherein:

a filename of said XML content identifier is inserted in a “

src=”

list in a <

presence . . . >

section of said modified PIDF-LO data.

4. The method of associating a geospacial location to content on a network according to claim 1, wherein:

a filename of said XML content identifier is inserted in a “

src=”

list in a <

presence . . . >

section of said modified PIDF-LO data.

5. The method of associating a geospacial location to content on a network according to claim 1, wherein:

said filename of said XML content identifier is inserted in a “

name=”

list in said <

presence . . . >

section of said modified PIDF-LO compliant data.

6. The method of associating a geospacial location to content on a network according to claim 1, wherein:

said geospacial location information identifies a specific zone.

7. The method of associating a geospacial location to content on a network according to claim 6, wherein:

said specific zone is defined using a coordinate based polygon system.

8. The method of associating a geospacial location to content on a network according to claim 7, wherein:

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

9. The method of associating a geospacial location to content on a network according to claim 1, wherein:

said geospacial location information identifies a specific latitude/longitude.

10. The method of associating a geospacial location to content on a network according to claim 1, wherein:

said geospacial location information is defined directionally.

11. The method of associating a geospacial location to content on a network according to claim 1, wherein:

said network is an Internet.

12. The method of associating a geospacial location to content on a network according to claim 1, wherein:

said network is a corporate Intranet.

13. The method of associating a geospacial location to content on a network according to claim 1, wherein:

said network is a corporate Extranet.

14. The method of associating a geospacial location to content on a network according to claim 1, wherein:

said XML content comprises text.

15. The method of associating a geospacial location to content on a network according to claim 1, wherein:

said XML content comprises at least one image.

16. The method of associating a geospacial location to content on a network according to claim 1, wherein:

said XML content comprises audio.

17. The method of associating a geospacial location to content on a network according to claim 1, wherein:

said XML content comprises video.

18. The method of associating a geospacial location to content on a network according to claim 1, wherein:

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

19. The method of associating a geospacial location to content on a network according to claim 1, further comprising:

tagging descriptive information relating to said XML content identifier in a <

presence . . . >

section of said modified PIDF-LO data.

20. The method of associating a geospacial location to content on a network according to claim 19, wherein:

said tagged descriptive information is included in a <

presence . . . >

section of said modified PIDF-LO data.

21. The method of associating a geospacial location to content on a network according to claim 19, wherein:

said tagged descriptive information includes a “

virtual=”

tag.
