ISO 19109 the document has a fee like other ISO documents (I will  
never understand this...). However, many of the ISO 191nn specs have  
their equivalents in the OGC Abstract Specifications ( http:// 
www.opengeospatial.org/standards/as ) and in this case, the model is  
described in Topic 5: Features.

We have discussed further the "roots" of NeoGeo. Although a geometry  
should not itself be a feature, one possibility will be that both can  
be considered SpatialThing's. In that case, the domain of  
_featureproperty is _Feature, but the range of georss:where is  
_Geometry. Whether _Feature is necessarily spatial is another  
question, but this will do for now.

               Thing
                  |
        SpatialThing
        /                   \
_Feature         _Geometry
           \               /
        georss:where

This is the latest version I have locally.

This is a question to Chris Goad (of course, it has been a reliable  
link up until now). Chris, could you perhaps include the ontology  
itself on the wiki, or should I do that?
