i use this command to extract links dumps
python wda-export-data.py -e turtle-links

then this command to convert the links dump from turtle to Ntriples format
rapper -i turtle turtle-20130811-links.ttl > turtle-20130811-links.nt

but the extracted dumb appears to have some syntax errors considering some < bracket specifically in line 13250337

rapper: Error - URI file:///root/hady_wikidata_extraction/wda/results/turtle-20130811-links.ttl:13250337 - syntax error at '<'

notes :

• this error existed also before the new python script edits but a little lines above
• i suggest using this command in order to test the dump issues before uploading it :
  rapper -i turtle turtle-20130811-links.ttl > turtle-20130811-links.nt
