---------------------------

             Summary: RIOT parse many files at once, output only valid ones
                 Key: JENA-1325
                 URL: https://issues.apache.org/jira/browse/JENA-1325
             Project: Apache Jena
          Issue Type: Improvement
          Components: RIOT
         Environment: GNU/Linux
            Reporter: Laura


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

    riot \
        --verbose \
        --stop \
        --check \
        --strict \
        --output=nt \
        files/*.rdf > files.nt

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.
