Hi Ryan,
There is an option when creating a parser to provide different policies
for generating the internal system identfier for a blank node.
RDFParser.create()..labelToNode(...)...
It shouldn't depend on JenaParameters.disableBNodeUIDGeneration but
there is a bug in the Turtle parser (JENA-2274) where it uses the core
blank node id allocator so you'll need teh global flag as well.
public static void main(String... args) {
// Blank nodes in [] and in an RDF collection (AKA list)
String s = "PREFIX : <http://example/> :s :p [ :q (1 2) ] .";
JenaParameters.disableBNodeUIDGeneration = true;
LabelToNode bnodes = LabelToNode.createIncremental();
StreamRDF output =
StreamRDFWriter.getWriterStream(System.out, Lang.NT);
RDFParser.create()
.fromString(s)
.lang(Lang.TTL)
.labelToNode(bnodes)
.parse(output);
}
The NT writer shows the label (it adds the "_:B")
Output at 4.4.0 (some URIs shortened to use in email).
_:BA100000 rdf:first "1"^^<http://www.w3.org/2001/XMLSchema#integer> .
_:BA100000 rdf:rest _:BA100001 .
_:BA100001 rdf:first "2"^^<http://www.w3.org/2001/XMLSchema#integer> .
_:BA100001 rdf:rest <http://www.w3.org/1999/02/22-rdf-syntax-ns#nil> .
_:BX400 <http://example/q> _:BA100000 .
<http://example/s> <http://example/p> _:BX400 .
There are two series of bnode here : BA100.. for lists and BX40.. for
other blank nodes.
That will change to something like:
_:B0001 rdf:first "1"^^<http://www.w3.org/2001/XMLSchema#integer> .
_:B0001 rdf:rest _:B0002 .
_:B0002 rdf:first "2"^^<http://www.w3.org/2001/XMLSchema#integer> .
_:B0002 rdf:rest <http://www.w3.org/1999/02/22-rdf-syntax-ns#nil> .
_:B0000 <http://example/q> _:B0001 .
<http://example/s> <http://example/p> _:B0000 .
and JenaParameters.disableBNodeUIDGeneration is not used when
https://issues.apache.org/jira/browse/JENA-2274
happens.

Ryan,
Please, could you show example code that illustrates what you are seeing? Presumably it
isn't a mix in one parser run because it looks like "Annn" come from a
different place than UUIDs Ids.
