Fair enough, I need to post the draft Note this week which will  
explain the neogeo concepts a bit more clearly. The serialization  
should be the same as GeoRSS, so the examples there should be useful  
(which we also need to expand).

Chris, what do you think about adding in geo:lat and geo:long to  
neogeo for "backwards compatibility", at least for now? There will  
presumably be a mixed reaction, but compatibility would be useful as  
long as we clearly indicated how the properties are being defined in  
the context of the newer ones.

The immediate question is what to do past this week once the  
incubator expires. Should we continue with experimentation through  
georss.org or SWIG? Others have supported establishing a GWIG  
(geosemantic web interest group), but it clearly needs canvassing of  
support to go forward. In particular, we need a vibrant forum if we  
are going to formulate any Recommendation level work such as the  
geospatial relationship markup language (GRML?) that Mike and I have
