Andy Seaborne commented on JENA-1864:
-------------------------------------
On 1: It looks to me like the change is to {{StreamRDFOps.sendGraphToStream}}
to take the base as well as the prefix map.
Note that some people have asked for output using base but without the \@base.
However, we have said that it is the app responsible to remove the \@base and
that Jena produces portable data output (get the same RDF anywhere).
Bonus points for adding a switchable @base using the context to pass the option.
On 3: {{NodeFormatterTTL}} could do the escaping (in cooperation with
SplitIRI). The code simply does not exist ATM but it is the right place.
> Inconsistent Turtle serializers
> -------------------------------
>
> Key: JENA-1864
> URL: https://issues.apache.org/jira/browse/JENA-1864
> Project: Apache Jena
> Issue Type: Bug
> Affects Versions: Jena 3.14.0
> Environment: My Configuration:
> OS: Ubuntu 18.04
> java version "1.8.0_111"
> javac 1.8.0_242
> Jena Version: 3.14.0
> Reporter: Viresh Gupta
> Priority: Major
>
> The turtle serializers provided for default model in Jena don't work as
> expected. Moreover, the docs lack on which methods to use in which case.
> I found the following methods that seem to work:
> # model.write() (A.ttl)
> # RDFWriter (B.ttl)
> # RDFDataMgr (C.ttl)
> I'm providing a minimum working example along with the outputs using a sample
> turtle file from Turtle specifications (ggoblin.ttl – Example 1 from
> [https://www.w3.org/TR/turtle/|https://www.w3.org/TR/turtle/#sec-examples])
> in a gist: [https://gist.github.com/virresh/5a28dc3adb1f40bf9070e2cb4ecfa90d]
>
> The issue:
> # "@base" directive is not printed when writing with the TURTLE_BLOCK and
> TURTLE_FLAT format in RDFWriter
> # There is no way to provide "@base" inside the RDFDataMgr. Expected output
> was something like <#spiderman>
> # RDFDataMgr doesn't respect the prefix supplied, e.g I manually added
> prefix "@base", however, the output (C.ttl) still converts the relative
> entities into their absolute form, whereas I expected it to do something like
> base:#spiderman at the very least
>
> I'll be happy to help with the issue if it doesn't fall into the "wont-fix"
> category.
