Hi,
I just did an extraction for the German Dataset, and noticed an error while trying to import external_links_de.nt in Virtuoso (Using the latest revision from the repo). The error mentioned is
" File /export/local-1/outputDir/de/external_links_de.nt error 2
3000 SR133: Can not set NULL to not nullable column 'DB.DBA.RDF_QUAD.O' " .
I then tried to validate the file with OpenRDF Sesame and Jena. Sesame complains about Unescaped Backslashes and dies:
( You can find the file I mentioned here: http://de.dbpedia.org/invalidfiles/external_links_de.nt )
org.openrdf.rio.RDFParseException: Unescaped backslash in: http://de.dbpedia.org/resource/X:\_No_Way_Out [line 1013701] (Probably not the cause Virtuoso can't load it, since it appears in other files also)
And Jena complains about some other errors:
ERROR [main] (RDFDefaultErrorHandler.java:40) - Syntax error at line 1013701 position 36: expected "u"
ERROR [main] (RDFDefaultErrorHandler.java:40) - Syntax error at line 1013702 position 36: expected "u"
Any idea what's causing the Virtuoso import problem ?
Seems to be fixed: see http://dbpedia.org/page/ X:%5C_No_Way_Out
sorry, had to split the URL - sourceforge says "XSRF attempt detected" :-)
