Hi,
The the RDF triple example you give is just a matter of format.
But anyway according to ur words, I think what you want is to generate a
single file with the format u want, and I will tell you how to generate it.
Forget the protege I've just mentioned, and
follow the following codes and try to adapt to ur codes.
Create three class, 1) define ur concept/schema 2) contain the main
function and generate rdf data 3) output a file u want :
--------------------------------------------
1) CustomizedSchema.java
// define ur class, conceptual level thing,
Public class CustomizedSchema {
public static final String URI = "http://
your_URI<http://define_your_URI>
";
private static Model m = (Model) ModelFactory.createDefaultModel();
// define the properties, public static final Property propertyName1 =
m.createProperty(URI, "propertyname1");
public static final Property propertyName2= m.createProperty(URI,
"propertyname2");
// and so on...
}
2) MainGenerator.java
public class MainGenerator {
public static final String URI = "http:// your_URI<http://define_your_URI>
";
Model model = ModelFactory.createDefaultModel();
Resource sub = model.createResource(URI+"subName");
model.add(sub, CustomizedSchema.propertyName,"ur value");
GenerateRDFFile.writeModel(model);
}
3) GenerateRDFFile.java
public class GenerateRDFFile {
public static void writeModel(Model model){ File f = new File("give a rdf
file path and name"); Model modelBase; try{ //read the old data.rdf
if(f.exists()){ modelBase = FileManager.get().loadModel(rdfDataName); }
else{ modelBase = ModelFactory.createDefaultModel(); } Model uniform =
modelBase.union(model); OutputStream out = new FileOutputStream(f); //write
and close; uniform.write(out,"TURTLE"); out.close(); } catch (Exception e){
System.out.println("Error:"+e.getMessage()); } }
}
------------------------------------------
That's all, right?
Hope you can succeed, :)
Best regards,
Dongsheng wang
