Andy Seaborne updated JENA-1966:
--------------------------------
Description:
The base URI of a jsonLD file doesn't appear to be swapped out correctly. The
first "./" is replaced correctly with the specified base, but after that, blank
nodes that don't end up in the final graph seem to be created.
See:
[https://github.com/ebremer/jenabug]
using the following code to read in a JSON-LD file:
{noformat}
Model m = ModelFactory.createDefaultModel();
InputStream inputStream = new FileInputStream("demo.jsonld");
RDFParser.create().base("[https://demo.com|https://demo.com/]";).source(inputStream).lang(RDFLanguages.JSONLD).parse(m);
System.out.println("Number of triples : "+m.size());
RDFDataMgr.write(System.out, m, Lang.NQUADS);
{noformat}
demo.jsonld:
{noformat}
{
"@context": [
"https://w3id.org/ro/crate/1.0/context";
],
"@graph": [
{
"@id": "another/local/3223423423/blam.ttl",
