> 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. Writing *.format.gz with the command line is probably as much within remit of someone using riot on the command line as for reading those.
> 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}
