             Summary: riot: gzip output option
                 Key: JENA-959
                 URL: https://issues.apache.org/jira/browse/JENA-959
             Project: Apache Jena
          Issue Type: New Feature
          Components: RIOT
            Reporter: Stian Soiland-Reyes
            Priority: Trivial


The riot command line tool supports incoming file formats like *.ttl.gz, but 
there is no (obvious) way to also output in compressed formats.

This can of course also be achieved with piping and gzip, but that is easily 
platform-specific and not so easily 

So my suggestion is to support extension .gz in the various --output options to 
enabled outputting via a GzipOutputStream -- 
http://docs.oracle.com/javase/7/docs/api/java/util/zip/GZIPOutputStream.html

For example:

{code}
stain@biggie-utopic:~/Downloads$ riot --output=nquads.gz 
chembl_20.0_target_targetcmpt_ls.ttl.gz 
Not recognized as an RDF language : 'nquads.gz'
{code}
