The file has @type @id > "rdfs:label" and "rdfs:comment" and also ranges and domains. I have a test > java program like this > {noformat} > Model m = ModelFactory.createDefaultModel(); > Reader fileReader = new FileReader(fileName); > Model model = m.read(fileReader, null, "JSON-LD"); > StmtIterator it = model.listStatements(); > Set<String> set = new HashSet<>(); > System.out.println("Labels"); > while (it.hasNext()) { > Statement statement = it.next(); > {noformat} > .... It seems to pick up all the content but does not see the @type > statements with rdfs:container. How do I pick up these statements using this > parser? > A fragment of the json-ld is \{ "@id": "aaa:bbb", "@type": [ "rdfs:container" > ], "rdfs:label": { "@language": "en", "@value": "cccc" }, "rdfs:comment": \{ > "@language": "en", "@value": "dddd." }, "rdfs:member": [ \{ "@id": > "aaaa:eeee" }, \{ "@id": "aaaa:fffff" } ], > When the type is rdfs:class - I get a statement coming through with predicate > "type" and the object as the RDFClass, but when the type is rdfs:container - > as in the above example I do not get a statement through. I was expecting a > statement to come through with the predicate of "type" and a subject with > localName of bbb and an object specifying the container class. I do not see > such a statement. How to I detect in the parser that the presence of the > rdfs:container? The presence of the container tag is very meaningful for our > parser. We are looking at alternative ways of representing this sort of > information in the model because of this issue. > I notice Jena has the concept of Container : > [https://jena.apache.org/documentation/javadoc/jena/org/apache/jena/rdf/model/Container.html]. > I can see write orientated methods that refer to this. -- This message was sent by Atlassian Jira (v8.3.4#803005)
