---------------------------

             Summary: org.apache.jena.riot.RDFDataMgr converter to JSONLD 
problem
                 Key: JENA-765
                 URL: https://issues.apache.org/jira/browse/JENA-765
             Project: Apache Jena
          Issue Type: Bug
          Components: RIOT
    Affects Versions: Jena 2.12.0
         Environment: Linux, eclipse, junit test
            Reporter: Marcin


Convertion from N-TRIPLE to JSONLD return a random JSONLD format. For example 
for constatn Ntriples string 'testNtriples' RDFDataMgr.write(osData, 
modelJena.getGraph(), Lang.JSONLD); return random JSONLD string by execution:
a) execution 1 return string:
{
    "@id" : "_:b3",
    "@type" : "http://rdf.data-vocabulary.org/#Breadcrumb";,
    "http://rdf.data-vocabulary.org/#title"; : {
      "@language" : "pl",
      "@value" : "Foto"
    },
    "http://rdf.data-vocabulary.org/#url"; : {
      "@id" : "http://www.fake.com/foto.html";
    }
  }, 
...

b) execution 2 return string:
{
  "@graph" : [ {
    "@id" : "_:b0",
    "@type" : "http://rdf.data-vocabulary.org/#Breadcrumb";,
    "title" : {
      "@language" : "pl",
      "@value" : "Aparaty Cyfrowe Nikon "
    },
    "url" : "http://www.fake.com/site/cat/2/filtr/_283_0_0_0_0_0_0_0_0_0";
  }, {
    "@id" : "_:b1",
    "@type" : "http://rdf.data-vocabulary.org/#Breadcrumb";,
    "title" : {
      "@language" : "pl",
      "@value" : "Foto"
    },
    "url" : "http://www.fake.com/foto.html";
  }, 
...
