Iain, very glad to hear of your progress, have a few points of reference

One of the things that I wanted to look at in Open Correspondence is the
spatial and temporal information that exists in the letters.
I run a place-name text mining web service at the EDINA data centre, and
would be more than happy to run some of your text and metadata through
it and do a little analysis of the results.

Jo, many thanks for this. I'll certainly be contacting you soon about
this once the current fixes and updates have been applied.
The backend is developed by the Language Technology Group at the
University of Edinburgh - they do some temporal/event text mining as
well (for example, resolving "last Tuesday" to a specific date relative
to the rest of the text, and connecting it to clusters of actions).
I forwarded your message to LTG folk, maybe it'll spark something.
Thanks, I believe that you've forwarded a reply so I'll get on top of
that today.
I had thought of trying to use Google maps to show the data for Collins
but I'm sure that there is a better way of doing it.
OpenLayers is likely the best option for doing this with open source /
data. http://openlayers.org/ - worth also looking at the new-ish
http://polymaps.org/ that Stamen released with SimpleGeo for doing more
complex visualisations with SVG overlays.
Looks fun and useful. I did like the idea of using historical maps that
you posted on the mapping hacks site, so an embarrassment of riches to
think about and play with for the next full release.
The RDF endpoint does not expose the geographical data yet as I'm not
sure of the best / most useful ontology to use though browsing there is
some W3C work and opengeospatial has various vocabularies / ontologies
There's a GeoSPARQL standard going through the OGC right now. The effort
is Oracle-led and so corresponds to their splinter of GeoSPARQL.
I'm not sure if OpenLink are involved - i should join the working group
- but i've seen/heard good things about the geographic SPARQL query
support in Virtuoso - it's being used for http://linkedgeodata.org - the
RDF version of OpenStreetmap.
It is not an area that I have much experience in yet (but it does seem
that both MySQL and Postgresql support GIS to some degree though again
better tools may exist)
PostGIS is the gold standard here, really. There's also a new wave of
spatial extensions to NoSQL stores which, if you're into the fun of the
learning experience, would be worth looking into.
GeoCouch for couchdb:

MongoDB geospatial indexing:

I've been looking at Couch so that gives me plenty to work with and
learn once I'm up to speed in the area.
Thanks,
Iain
