In case you still want to do it on your own for whatever reason I would recommend our CSV on the Web based parser, which is streaming-capable. GTFS generates a *lot* of data so streaming is a must. https://github.com/rdf-ext/rdf-parser-csvw This is for example used here: https://github.com/zazuko/blv-tierseuchen-ld Node.js based, not JVM. regards Adrian
