Hello, I need to import large n-triple files (dbpedia) into a tdb.
The problem is, that many of the triples are not valid (like
missing '<' or invalid chars) and leading to an exception which
quits the import... I just want to skip them and continue, so that
all valid triples are in the tdb at the end.
Is there a possibility to do that easily? I tried to rewrite the
ARQ, but this is very complex With friendly regards Stefan

You'd be much better off finding an n-triple parser that kept going
and also spat out (working) n-triples for piping to TDB. I can't see
an option like that in the riot command line.
There isn't such an option - there could be (if someone wants to
contribute a patch).
This is a typical ETL situation - you're going to have to clean those
triples (which were not written by an RDf tool presumably). Do you want
to loose them or fix them?
Checking before loading is always a good idea, especially data from
outside and other tools. When I receive TTL or RDF/XML, I parse to NT
which means its then checked. Then load the data.
