fwiw, the mapped SPARQL query then looks like this:

$ ./bin/spotlight2sparql 'kMDItemContentTypeTree=="public.jpeg"cd&&InRange(kMDItemLastUsedDate,$time.iso(2014-03-10T23:00:00Z),$time.iso(2014-04-10T22:00:00Z))'
SELECT DISTINCT ?url WHERE { ?obj nie:url ?url FILTER(regex(?url, '^file:///Volumes/test/')) . ?obj nie:mimeType 'image/jpeg' . ?obj nfo:fileLastAccessed ?a FILTER (?a > '2014-03-10T23:00:00Z' && ?a < '2014-04-10T22:00:00Z')}
