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/>

: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 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
