-----------------------------------------
Summary: riot cmdline uses wrong base when parsing Turtle over http
Key: JENA-1161
URL: https://issues.apache.org/jira/browse/JENA-1161
Project: Apache Jena
Issue Type: Bug
Components: Cmd line tools
Affects Versions: Jena 3.0.1
Reporter: Stian Soiland-Reyes
Parsing a Turtle file served over http:// or https:// which has got no @base,
and uses relative IRI references, wrongly uses the current directory in
file:/// as a base.
The command line
{code}
stain@biggie:/tmp$ riot
https://cdn.rawgit.com/stain/3d49908d790c5678faee302ba17f4a43/raw/bceb24ee6bfcaa60c4508779bc5f09ec367876f1/nobase.ttl
{code}
where that URL returns Content-Type: text/turtle;charset=utf-8 with the body:
{code}
@prefix : <#> .
<> :a <#test> .
{code}
is wrongly parsed by the riot command line tool to be relative to the current
directory:
{code}
<file:///tmp/https:/cdn.rawgit.com/stain/3d49908d790c5678faee302ba17f4a43/raw/bceb24ee6bfcaa60c4508779bc5f09ec367876f1/nobase.ttl>
<file:///tmp/https:/cdn.rawgit.com/stain/3d49908d790c5678faee302ba17f4a43/raw/bceb24ee6bfcaa60c4508779bc5f09ec367876f1/nobase.ttl#a>
<file:///tmp/https:/cdn.rawgit.com/stain/3d49908d790c5678faee302ba17f4a43/raw/bceb24ee6bfcaa60c4508779bc5f09ec367876f1/nobase.ttl#test>
.
{code}
The expected output would be the same as supplying the same URI as a --base:
{code}
stain@biggie:/tmp$ riot --base
https://cdn.rawgit.com/stain/3d49908d790c5678faee302ba17f4a43/raw/bceb24ee6bfcaa60c4508779bc5f09ec367876f1/nobase.ttl

.
{code}
(except if a Content-Location header is provided, or HTTP redirection has been
followed - in which case the result of that should be used as base)
