Andy Seaborne updated JENA-1325:
--------------------------------
Description:
This issue is more or less related to this other one
https://issues.apache.org/jira/browse/JENA-1322
I have a folder with thousands of files, mostly small RDF/XML files. I'm using
RIOT to validate them and dump the valid ones into ntriples files. The problem
is that calling RIOT on each file is not going to cut it. The overhead is
significant enough that this operation is just too slow (hours). So I've tried
to call RIOT only once on all files together using
{noformat}
riot \
--verbose \
--stop \
--check \
--strict \
--output=nt \
files/*.rdf > files.nt
{noformat}
and in this way validation is much faster. The problem is, that it's still
dumping invalid files to the .nt output file. I'm downloading these files from
the Internet, so I'm not going to fix them myself, I just want to skip bad
files.
Now, to be clear, I understand that RIOT is of course not meant to fix bad
data, and I'm not asking for this. I'm suggesting however to add an *--option*
such that RIOT can do the following:
1. parse multiple files at once (so that there is no need to invoke the same
RIOT command for each file)
2. for every file, check/validate it
3. if *--output* is set, only output those files or triples that didn't raise
any ERROR
I think this is well in the scope of RIOT functionalities. Could this option
please be added to RIOT?
Thank you.
