-----------------------------------
Summary: sdbdump refuses to output a graph as Turtle
Key: JENA-1188
URL: https://issues.apache.org/jira/browse/JENA-1188
Project: Apache Jena
Issue Type: Bug
Components: SDB
Affects Versions: Jena 3.1.0
Reporter: Osma Suominen
I upgraded SDB to the 3.1.0 release version after running a snapshot build from
early February. This broke a script that I use to periodically back up a SDB
database:
{noformat}
sdbdump --sdb=$SDBROOT/sdb-yso.ttl \
--graph=http://www.yso.fi/onto/yso/ \
--out=TTL >$TTLFILE
{noformat}
This now gives the error
{noformat}
Not a 'quads' language (try 'N-Quads' or 'TriG')
{noformat}
The culprit seems to be this commit made on 8 Feb:
https://github.com/apache/jena/commit/cb449523c83832ceb9cf525b4b1e1f382c49c16f
I can see the point of requiring a quad-capable output format when dumping all
graphs (though I'm not sure it should be a fatal error even in that case), but
in my case, I asked for a single graph only. I think the check is overly strict.
