Hi Alex,
great to hear that, you are welcome.
Something similar using Lucene Spatial capabilities instead of
a proper GIS is here (it's just a less than two days hack):
https://github.com/castagna/GeoARQ
I was planning to post something along the lines of "making
easier to plug LARQ or similar into ARQ", but unfortunately I do
not a good idea (yet).
It would be good to enable third parties to add their own property
functions (that's possible) which use custom indexes and need to
update those indexes as triples/quads are added/removed to the
underlying RDF store.
More on this later, in the meantime: welcome.

Hi all,
We've currently got a lot of (simple) geospatial data in
<http://data.clarosnet.org/> (served behind the scenes by Fuseki).
We'd like to do some geospatial indexing magic, and were wondering
about writing something a bit like LARQ that will pull out things like
geo:Points and WKT literals, place them in a PostGIS-flavoured DB, and
then implements something like GeoSPARQL (<http://geosparql.org/>).
Has anyone started doing this or something similar? I'm happy to give
it a go and I'm sure my employer would be happy to contribute it back
to Jena and the ASF. My plan was to go through the LARQ codebase to
work out how it hooks itself in, and use that as a model.
Yours,
Alex
