У меня есть файл совой, и я пытаюсь запустить запросы на него, но не получаю никаких результатов, пожалуйста, кто-то поможет мне понять это и объяснить основной запросSPARQL запрос с использованием РДФ: ID не возвращает никаких результатов
public static void main(String[] args) {
String filename="H:/Samson_study/nodeTest/hRESTS-TC3/ontology/ApothecaryOntology.owl";
Model model=ModelFactory.createDefaultModel();
OntModel model1=ModelFactory.createOntologyModel(OntModelSpec.OWL_DL_MEM,model);
try
{ File file=new File(filename);
FileInputStream reader=new FileInputStream(file);
model.read(reader,null);
String query1=" PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> PREFIX my: <http://127.0.0.1/ontology/ApothecaryOntology.owl#> SELECT ?result WHERE { ?result rdf:ID my:HealthInsuranceNumber .}";
Query query=QueryFactory.create(query1);
QueryExecution exe=QueryExecutionFactory.create(query, model1);
ResultSet RES=exe.execSelect();
ResultSetFormatter.out(System.out, RES, query);
}catch(Exception e)
{
e.printStackTrace();
}
}
онтология выглядит следующим образом:

Я не получаю ошибку, но я не знаю, как запросить филин файл, пожалуйста, помогите
Вы загружаете файл в свой «модельный» объект, но затем запрашиваете «model1». Вместо этого попробуйте model1.read (reader, null). –
еще не получил ответа –
Есть ли у вас какие-либо лица в онтологии, или у вас есть только схема? –
