I have been slowly updating the terminology wiki. 

You will notice that a number of the additional terms I added have to do 
with coordinates, coordinate reference systems, and so forth. These are 
derived from an ISO standard (19111) which is based on numerous agreements 
between and among national mapping agencies, defense agencies, and the oil 
and gas exploration community (and others).

As AR will require the fusion of location enabled resources from many 
sources in various formats and in various coordinate reference systems, the 
ability to at a minimum state metadata regarding the CRS is key. Otherwise, 
when visualized (as an example) POIs may not be at their proper location! 
Unfortunately just stating something like WGS 84 is not sufficient, 
especially on a global basis. For example, in China there is a law that 
states what the national CRS is and it is not WGS 84. Same in Taiwan, India 
and so forth. Of course we can state that the default is always WGS 84, 2d 
or 3d as defined EPSG 4326. But to be truly extensible, any POI model will 
need to be able to provide at a minimum optional CRS metadata.

Tuesday night missive.

As per my ACTION-11, I took a crack at making this look a bit better.  I'm 
not sure it was very effective, but I just transformed it from a table to a 
definition list.

Note that definition lists is one place where we vary significantly in style 
from the default mediawiki style, see:

I'll likely be tweaking our stylesheets, any suggestions are welcome.
