  13. $Log: wgs84_pos.rdf,v $
  14. Revision 1.22 2009/04/20 15:00:30 timbl
  15. Remove the time bits which have been deal with elsewhere eg in iCal.
  16. Revision 1.21 2009/04/20 12:52:47 timbl
  17. try again
  18. Revision 1.20 2009/04/20 12:42:11 timbl
  19. Add Event (edited ages ago and never checked in), and location (following discussion http://chatlogs.planetrdf.com/swig/2009-04-20#T12-36-09)
  20. Revision 1.19 2009/04/20 12:36:31 timbl
  21. Add Event (edited ages ago and never checked in), and location (following discussion http://chatlogs.planetrdf.com/swig/2009-04-20#T12-36-09)
  22. Revision 1.18 2006/02/01 22:01:04 danbri
  23. Clarified that lat and long are decimal degrees, and that alt is decimal metres about local reference ellipsoid
  24. Revision 1.17 2004/02/06 17:38:12 danbri
  25. Fixed a bad commit screwup
  26. Revision 1.15 2003/04/19 11:24:08 danbri
  27. Fixed the typo even more.
  28. Revision 1.14 2003/04/19 11:16:56 danbri
  29. fixed a typo
  30. Revision 1.13 2003/02/19 22:27:27 connolly
  31. relaxed domain constraints on lat/long/alt from Point to SpatialThing
  32. Revision 1.12 2003/01/12 01:41:41 danbri
  33. Trying local copy of XSLT doc.
  34. Revision 1.11 2003/01/12 01:20:18 danbri
  35. added a link to morten's xslt rdfs viewer.
  36. Revision 1.10 2003/01/11 18:56:49 danbri
  37. Removed datatype range from lat and long properties, since they would
  38. have required each occurance of the property to mention the datatype.
  39. Revision 1.9 2003/01/11 11:41:31 danbri
  40. Another typo; repaired rdfs:Property to rdf:Property x4
  41. Revision 1.8 2003/01/11 11:05:02 danbri
  42. Added an rdfs:range for each lat/long/alt property,
  43. http://www.w3.org/2001/XMLSchema#float
  44. Revision 1.7 2003/01/10 20:25:16 danbri
  45. Longer rdfs:comment for Point, trying to be Earth-centric and neutral about
  46. coordinate system(s) at the same time. Feedback welcomed.
  47. Revision 1.6 2003/01/10 20:18:30 danbri
  48. Added CVS log comments into the RDF/XML as an rdfs:comment property of the
  49. vocabulary. Note that this is not common practice (but seems both harmless
  50. and potentially useful).
  51. revision 1.5
  52. date: 2003/01/10 20:14:31; author: danbri; state: Exp; lines: +16 -5
  53. Updated schema:
  54. Added a dc:date, added url for more info. Changed the rdfs:label of the
  55. namespace from gp to geo. Added a class Point, set as the rdfs:domain of
  56. each property. Added XML comment on the lat_long property suggesting that
  57. we might not need it (based on #rdfig commentary from implementors).
  58. revision 1.4
  59. date: 2003/01/10 20:01:07; author: danbri; state: Exp; lines: +6 -5
  60. Fixed typo; several rdfs:about attributes are now rdf:about. Thanks to MortenF in
  61. #rdfig for catching this error.
  62. revision 1.3
  63. date: 2003/01/10 11:59:03; author: danbri; state: Exp; lines: +4 -3
  64. fixed buglet in vocab, added more wgs links
  65. revision 1.2
  66. date: 2003/01/10 11:01:11; author: danbri; state: Exp; lines: +4 -4
  67. Removed alt from the as-a-flat-string property, and switched from
  68. space separated to comma separated.
  69. revision 1.1
  70. date: 2003/01/10 10:53:23; author: danbri; state: Exp;
