As well as the more experimental stuff, I’ve also produce several more useful tools:
sparql2kml
http://graphite.ecs.soton.ac.uk/sparql2kml/ – This takes a SPARQL query which returns ?lat,?long (or ?georss) and ?title and maybe ?desc and ?placename and produces a KML file so you can see it on Google Maps or Earth!
As an experiment I used the following to find the birth place of Southampton football players.
PREFIX dbo: <http://dbpedia.org/ontology/>
PREFIX dbpedia: <http://dbpedia.org/resource/>
SELECT DISTINCT ?georss ?title ?placename WHERE {
?person dbo:team <http://dbpedia.org/resource/Southampton_F.C.> .
?person dbo:birthPlace ?place .
?place <http://www.georss.org/georss/point> ?georss .
?person rdfs:label ?title . FILTER langMatches( lang(?title), “EN” ) .
OPTIONAL { ?place rdfs:label ?placename . FILTER langMatches( lang(?placename), “EN” ) }
OPTIONAL { ?x <http://dbpedia.org/property/county> ?place }
FILTER (!bound(?x) && ?place != <http://dbpedia.org/resource/England> && ?place != &l
t;http://dbpedia.org/resource/Wales> )
t;http://dbpedia.org/resource/Wales> )
}
View it: Google Maps or KML for Google Earth.
excel2csv
This one is dead simple. It converts an excel file into comma separated values.
sparqllib.php

Nice and simple library to let you use SPARQL from PHP. The function names are deliberately copied from the mysql ones so you have sparql_connect, sparql_fetchrow etc.
