Viresh Gupta commented on JENA-1864:
{{> WriterStreamRDFBase}} can acquire a {{Context}} - I've done that my copy
(small change, but quite a files altered! The wonders of Eclipse signature
change!) and I can PR that after PR #179 is merged
Is there a issue that I can track so that I know when to move forward with the
custom base printing options?

However, I think we need to change the StreamRDF interface to incorporate something like `StreamRDF::base(String base, boolean hide_base)`. This is already present for prefixes and triples inside StreamRDF. >From my understanding, calls to prefix() actually emit a prefix to stream, >whereas base() wasn't emitting it previously and just setting the >NodeFormatter. Since we don't have any context inside StreamRDFOps, we will >have to design StreamRDFOps.sendBaseToStream() which will use >StreamRDF::base(base, hide_base) to pass the information from context to >writer (via hide_base). I'm not yet sure if this is the solution you intended. Mostly concerned about changing the definition of the interface. Let me know if this looks right? > 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.

Thanks for clarifying 2 and pointers on 1. And for 3, Indeed removing the `\#` character gets the output in the expected format. Also, I didn't find any specifications on when to use the full range of escaped characters and when to use the other. Out of curiosity – Is it possible to tell NodeFormatterTTL about using escape characters or not? Probably unlikely that using absolute IRIs would be an issue to someone, although it would save some precious space while serializing to disk. I'll try to get a patch for 1 up sometime soon. Just to ensure stream writing isn't using some complicated and different mechanism: Patch should add a function `writeBase()` in `[writerStreamRDFBase|[https://github.com/apache/jena/blob/bfce1741cb12f9cf544235d32fba6598bc7341b5/jena-arq/src/main/java/org/apache/jena/riot/writer/WriterStreamRDFBase.java#L43]]` similar to `[TurtleShell|[https://github.com/apache/jena/blob/34cc2b30b1a913da5704e4518387cf014f89ffec/jena-arq/src/main/java/org/apache/jena/riot/writer/TurtleShell.java#L91]]` and call it in TurtleWriterBlocks, and similarly new functions for the FlatWriter(s)? > 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.
