[jira] [Commented] (JENA-701) formatNTriples method for RDFNode

["Andy Seaborne (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/JENA-701?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14003973#comment-14003973 ] 

Andy Seaborne commented on JENA-701:
------------------------------------

Both {{NTripleWriter}} and {{N3JenaWriterCommon}} are legacy, left in place for maximum compatibility only. They are not used by {{model.write}} anymore if RIOT is on the classpath.

The new writers are in RIOT (in the jena-arq code base -- they deal with datasets as well as graphs).  The best way to read/write is to use {{RDFDataMgr}}.

In RIOT, you will find {{NodeFmtLib}} and {{NodeFormatter}}. SPARQL writing has {{FmtUtils}} (older than {{NodeFmtLib}}).

> I suggest that jena should have a method e.g. {{formatNTriples}} for the {{RDFNode}} interface which will output the N-Triples representation of this node. This can be helpful for generating SPARQL query strings and can unify code of {{NTripleWriter}} [1] and {{N3JenaWriterCommon}} [2].
> Currently {{NTripleWriter}} and {{N3JenaWriterCommon}} have their own implementations {{writeNode}} resp. {{formatNode}} for generating the correct String representation.
