an accuracy appropriate for the size of the object and uses such as mapping .

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