Actually, "38.926832, -77.03201" syntax is quite standard for technical presentation of geocoordinates. I agree, that it's very American in using "." for decimal separator, but it's standard de-facto (for example, Google uses it in queries and I use it in GvsY tool in URLs: http://www.sergeychernyshev.com/maps.html#49.008084,8.403756 ;) ).

Another alternative is to use ";" as separator (I doubt somebody uses it as decimal separator) so the result will be like this: "38,926832; -77,03201", but I still think that checking if comma splits into only two parts and then using previous example is best.

You can enter positive/negative decimal degrees in SMW 1.0 RC1, but
you're right that you must provide the degree symbol or its HTML
numeric entity code &#176;.  I filed enhancement bug 11679.

I updated http://ontoworld.org/wiki/Type:Geographic_coordinate with, I
believe, all the supported characters and separators.  You could tell
users to copy and paste then modify a working format from that page.

Changing the code to not requiring a degree symbol is tricky.  I think
the code needs a degree symbol to give it something to split on.  Note
that in some languages comma is also a decimal separator
(smw_decseparator in the languages file) so you can't split into two
parts on comma.  Is there some other standard compact format for
coordinates?  Some tests are at
http://ontoworld.org/wiki/Geographic_coordinate_test
This isn't a regression from 0.7, it doesn't work there either.

As a workaround you could use a template like
http://en.wikipedia.org/wiki/Template:Coord and insert the degree
symbols in the semantic annotation it generates.

You can't use the character entity reference for degree (&deg;) and some
other entities and decimal references for minutes and seconds, which
seems an accidental oversight.  I came up with a patch to
SMW_DV_GeoCoords.php for that.
