Joshua Taylor created JENA-594:
----------------------------------
Summary: rdfcat silently ignores - as stdin if input type isn't
specified
Key: JENA-594
URL: https://issues.apache.org/jira/browse/JENA-594
Project: Apache Jena
Issue Type: Bug
Components: Cmd line tools
Affects Versions: Jena 2.11.0
Reporter: Joshua Taylor
Priority: Minor
Treatment of content from standard in by - and /dev/stdin differs when format
is not specified.
Using -, non RDF/XML content is silently ignored. Specifying -n gets it
treated correctly.

$ echo '<s> <p> <o>' | rdfcat -n -

<j.0:p rdf:resource="file:///home/taylorj/tmp/o"/>
</rdf:Description>

-n with /dev/stdin works, too. Using /dev/stdin with no format option blows
up, though. (It's not silently ignored like - was)
