I came across the following:
dice:~> /usr/share/java/jena/bin/rdfcat --help
Usage: java jena.rdfcat (option|input)*
Concatenates the contents of zero or more input RDF documents.
Options: -out N3 | N-TRIPLE | RDF/XML | RDF/XML-ABBREV
-n expect subsequent inputs in N3 syntax
-x expect subsequent inputs in RDF/XML syntax
-t expect subsequent inputs in N-TRIPLE syntax
-[no]include include rdfs:seeAlso and owl:imports
input can be filename, URL, or - for stdin
Recognised aliases for -n are: -n3 -ttl or -N3
Recognised aliases for -x are: -xml -rdf or -rdfxml
Recognised aliases for -t are: -ntriple
Output format aliases: x, xml or rdf for RDF/XML, n, n3 or ttl for N3,
t or ntriple for N-TRIPLE
See the Javadoc for jena.rdfcat for additional details.
Does this mean Jena 2.6.x did not support .nq format? Please confirm
as this will help me convince my boss to upgrade Jena
