Stuart; The sml:selectQuery property in CreateMap is the SPARQL query
that returns a resource that has geo:lat and geo:long values. I.e.
your IterateOverSelect is not necessary - put the query directly into
the CreateMap module. Also, the query results have to be a subject
(subject as in SOP) with the lat/long properties (not lat/long
variables). Here is a general query that will get all resources that
can be mapped:
SELECT ?subject
WHERE
{ ?subject geo:lat ?objx .
?subject geo:long ?objy .
}
You can put that directly into your CreateMap module.
