Andy Seaborne commented on JENA-431:
------------------------------------
The tests look like they are very old in origin.
There's no way to test for being an N-triples parser except to test it on
N-triples and since Turtle can parse valid N-triples, to identify an N-triples
only parser also requires testing negatives as well. We have always allowed
changing the parser - the tests just happened to run before an app could do
that but it's not true with RIOT initializing automatically.
It is probably historical that the NT parser accepts raw newlines -- I found
another historical feature for parsing XMLLiterals.I guess it all dates back to
different NT designs in the RDF working group. The outcome was one triple on
one line.
With RIOT, the role of the jena-core N-triples parser is back to the original
reason for its existence - testing RDF/XML output. As of Jena 2.10.0, users
are using RIOT parsers if they have jena-arq on the classpath as we encourage.
I have suggested we merge jena-arq and jena-core then re-modularise the code
base. Now we have a maven artifact "apache-jena-libs" we can chnage the
module structure of the implementation.
When Jena 2.10.1 is released and we are comfortable the new writers are
working, we can do that, including deleting the old core package "n3" (which
isn't N3 - it's Turtle). If people want to do further modularization, that
would be great but we can stil release
I fixed the parser and changed the test data to "foo\u000Abar".
(I don't understand AbstractTestPackage because it seems to adds individual
tests itself.)

> Reporter: Claude Warren
> Attachments: TestReaderDemo.tar.gz

> Similar to an earlier bug, when ARQ is included the readers that are returned
> fail the TestReaders tests. The same tests pass when ARQ is not included.
> The attached file includes a simple example.
