Hello,

Well the first question is really a trig question.

Trick question?

When is the new style BASE versus the old style @base to be preferred in trig 
files?

IMO Always.

To the parsers it makes no difference.

I set:
RIOT.getContext().set(RIOT.symTurtleDirectiveStyle, "sparql");

in projects to get it in output.


The RIOT question is in Jena 3.16.0 and earlier. I try:

     riot --count C1.trig

and get the result:

     C1.trig         : Quads = 43

which is correct. But when I try:

     riot --out=Turtle C1.trig > tmp.ttl

Different issue to BASE vs @base.

Because Turtle can't express named graphs so all you get is the default graph and the default graph is empty.

Try --out=trig

Try --out=TTL on:

PREFIX : <http://example/>

:s :p :o .
:g1 { :s1 :p1 :o1  }

PS "riot" is included ... in Fuseki jars!

java -cp apache-jena-fuseki-3.16.0/fuseki-server.jar riotcmd.riot -h




all I get is the prefix map:

@base          <bdg:C1> .
@prefix :      <http://purl.bdrc.io/ontology/core/> .
@prefix adm:   <http://purl.bdrc.io/ontology/admin/> .
@prefix bda:   <http://purl.bdrc.io/admindata/> .
@prefix bdg:   <http://purl.bdrc.io/graph/> .
@prefix bdr:   <http://purl.bdrc.io/resource/> .
@prefix owl:   <http://www.w3.org/2002/07/owl#> .
@prefix rdf:   <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
@prefix rdfs:  <http://www.w3.org/2000/01/rdf-schema#> .
@prefix skos:  <http://www.w3.org/2004/02/skos/core#> .
@prefix vcard: <http://www.w3.org/2006/vcard/ns#> .
@prefix xsd:   <http://www.w3.org/2001/XMLSchema#> .

The result I get is not dependent on the particular trig file. I see the same 
regardless as long as it is valid trig.

The result doesn’t appear to depend on whether I use riot or trig commands, 
with —out=Turtle or —out=TTL

The trig file, with the above prefixes, is:

I’m sure I’m doing something dum b here. I’m prompted to ask since the little 
tool I’ve been using (rdf2rdf-1.0.1-2.3.1.jar and rdf2rdf-1.0.2-2.3.1.jar) 
doesn’t like new style BASE.

Thanks,
Chris
