Hendy Irawan updated JENA-735:
------------------------------
Component/s: (was: RIOT)
Web site
Description:
https://jena.apache.org/documentation/io/rdf-output.html mentioned:
bq. This page describes the RIOT (RDF I/O technology) output capabilities
introduced in Jena 2.10.1. ... There are two ways to write RDF data using
Apache Jena RIOT, either via the RDFDataMgr ... or using the model API:
{code}
model.write(output, "format") ;
{code}
It should be mentioned in the documentation that using the model API has
limited supported formats, and Jena users should use RDFDataMgr because it's
typesafe and it supports all formats.
The Model API (I'm using {{DefaultModel}}) method throws exception for
{{TURTLE_FLAT}} (it works for {{TURTLE}}):
