Would it not be appropriate to simply embed the full RDF into the photo
rather than having to invent a new URI format for it, it's less limiting,
for the above URI, I presumably am limited to WGS 84 lat/lon's in certain
formats, and am forced onto a single time format.  Currently I have RDF
waypoints for the place I spend every night (since Feb 13th) and any places
where I travelled some distance in the day, this means I can relatively
easily provide some withinXm for all the photos I take assuming I know the
date of taking.  Embedding this inside the photos is pretty easy and
standard using Adobe's XMP format.

Plotting your file on my RDF consuming SVG is a little disappointing, as
although it finds two places in the file, it can't find labels for either of
the places, I need to improve how I find these, does anyone have any
suggestions of what I might do.
