- Recent changes to this namespace:
- $Log: wgs84_pos.rdf,v $
- 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.
- revision 1.1
- date: 2003/01/10 10:53:23; author: danbri; state: Exp;
- basic geo vocab

- Or a relationship between a park and its outline as a closed arc of points, or a road and
- its location as a arc (a sequence of points).
- Clearly in practice there will be limit to the accuracy of any such statement, but one would expect
- an accuracy appropriate for the size of the object and uses such as mapping .
