I have made an Ontologu in Protege and imported in Eclipse.My ontology already 10 instances and i want to add more instances.The following piece of code adds instances to existing class (Noun) of ontology. After excecution it do not update ontology model and shows same number of instances.
public static void main(String[] args) throws OWLException, IOException{
OWLOntologyManager manager = OWLManager.createOWLOntologyManager();
File file = new File("D:\\word.owl");{
OntModel model=ModelFactory.createOntologyModel(OntModelSpec.OWL_MEM_RULE_INF);
System.out.println("Model is called successfully");
OWLOntology ont = manager.loadOntologyFromOntologyDocument(file);
System.out.println("Loaded ontology: " + ont);
String SOURCE = ("D:\\word.owl");
String NS = SOURCE;
OntModel base = ModelFactory.createOntologyModel(OntModelSpec.OWL_MEM_RULE_INF);
base.read( SOURCE, "" );
OntModel inf =ModelFactory.createOntologyModel(OntModelSpec.OWL_MEM_RULE_INF, base );
OntClass Noun = base.getOntClass( NS + "Noun" );
Individual jack = base.createIndividual( NS + "Jack", Noun );
Individual Helley = base.createIndividual( NS + "Helley", Noun );
manager.saveOntology(ont);
System.out.println("Number of individuals: " + ont.getIndividualsInSignature().size());
}
}
}
Output
Model is called successfully
Loaded ontology:
Number of individuals: 10
I dont use that API but I can see your issue.
At the start of your code you create an OWLOntology object:
OWLOntology ont = manager.loadOntologyFromOntologyDocument(file);
And here is the issue, you do not alter ont anywhere in your code, so when you call the line below, it will only show/save the same 10 individuals that you loaded from file at the beginning of your code:
manager.saveOntology(ont);
System.out.println("Number of individuals: " + ont.getIndividualsInSignature().size());
So to fix this you need to somehow modify ont to include the new Individual before using the above lines.
This works:
import java.io.FileWriter;
import java.io.InputStream;
import org.apache.jena.ontology.Individual;
import org.apache.jena.ontology.OntClass;
import org.apache.jena.ontology.OntModel;

public class Mgt {
public static void main(String[] args) throws Exception {
String namespace = "http://www.semanticweb.org/Word#";
String file = "word.owl";
OntModel jenaModel = ModelFactory.createOntologyModel(OntModelSpec.OWL_MEM_RULE_INF);
InputStream in = FileManager.get().open(file);
jenaModel.read(in, null);
OntClass Noun = jenaModel.getOntClass(namespace + "Noun");
Individual Organization = Noun.createIndividual(namespace + "Organization");
jenaModel.add(Organization, RDF.type, Noun);
FileWriter out = new FileWriter("word.out.owl");
jenaModel.getWriter("RDF/XML-ABBREV").write(jenaModel, out, namespace);
out.close();
}
}
Note that namespace is not related to the file name.
Updated Code It gives Exception in thread "main" java.lang.NullPointerException

I am trying to use a model that is built on java. Here is the model main class:

I am getting this error:

I am not sure what the problem is. could you guys help? I think the problem has to do with some missing or clashing dependencies.
By the way, I am using Java "11.0.2" 2019-01-15 LTS and running the model in eclipse.
thank you
Objective : I want to read a WSDL and print the services in the WSDL, complex types and Complex type definitions.
Worked : I've used WSDL4J for reading WSDL and successfully able to print the services and their parameters (complex types). Now I want to read the complex type definitions which is available in XSD. I'm unable to read XSD .Is ther any way to do it ?
I'm getting XSModel as null

You can use xsd2java plugin with maven
https://github.com/qaware/xsd2java-gradle-plugin
Here is an example showing how to retrieve the XSModel from an XSD URL, and print the complex types declared therein.
import org.apache.xerces.impl.xs.XMLSchemaLoader;
import org.apache.xerces.impl.xs.XSComplexTypeDecl;
import org.apache.xerces.impl.xs.XSElementDecl;
import org.apache.xerces.xs.XSConstants;
import org.apache.xerces.xs.XSModel;
import org.apache.xerces.xs.XSNamedMap;
import org.apache.xerces.xs.XSTypeDefinition;
public class Test {
public static void main(String[] args) {
try {
String xsdURL = "http://fsharp.github.io/FSharp.Data/data/po.xsd";
XMLSchemaLoader xsLoader = new XMLSchemaLoader();
XSModel xsModel = xsLoader.loadURI(xsdURL);
// print global element declarations
System.out.println("\nGlobal Element Declarations:");
XSNamedMap globalElemDecls = xsModel.getComponents(XSConstants.ELEMENT_DECLARATION);
globalElemDecls.forEach((k,v) -> System.out.println((XSElementDecl) v));
// print global complex type declarations
System.out.println("\nGlobal Complex Type Declarations:");
XSNamedMap globalComplexTypeDecls = xsModel.getComponents(XSTypeDefinition.COMPLEX_TYPE);
globalComplexTypeDecls.forEach((k,v) -> System.out.println((XSComplexTypeDecl) v));
} catch (Exception e) {
e.printStackTrace();
}
}
}
If you got null at xsLoader.loadURI(xsdURL), it is likely there are some flaws in the given XSD file. For example, "White spaces are required between publicId and systemId". You might need to fix these flaws first.
#JasonPlutext,
Hi Jason! I tried the above code but it just replaces an totally the image deleting the whole template.
I would like to just replace/add a particular relationship of the image ,say
<Relationship Id="rId8" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/image" Target="../media/image10.png"/>
in place of rId8 i would like to replace rId7 image.
My Source Code:
public static void main(String[] args) throws Exception {
String inputfilepath = "C:\\Users\\saranyac\\QUERIES\\Estimation\\PPT-PSR\\PSR_Dev0ps\\PSRAutomationTemplate.pptx";
PresentationMLPackage presentationMLPackage = (PresentationMLPackage)OpcPackage.load(new java.io.File(inputfilepath));
MainPresentationPart pp = presentationMLPackage.getMainPresentationPart();
SlidePart slidePart = presentationMLPackage.getMainPresentationPart().getSlide(0);
SlideLayoutPart layoutPart = slidePart.getSlideLayoutPart();
System.out.println("SlidePart Name:::::"+slidePart.getPartName().getName());
String layoutName = layoutPart.getJaxbElement().getCSld().getName();
System.out.println("layout: " + layoutPart.getPartName().getName() + " with cSld/#name='" + layoutName + "'");
System.out.println("Master: " + layoutPart.getSlideMasterPart().getPartName().getName());
System.out.println("layoutPart.getContents()::::::::s: " + layoutPart.getContents());
//layoutPart.setContents( (SldLayout)XmlUtils.unmarshalString(SAMPLE_PICTURE, Context.jcPML));
// Add image part
File file = new File("C:\\Users\\saranyac\\PPT-PSR\\PSR_Dev0ps\\ppt\\media\\image10.png" );
BinaryPartAbstractImage imagePart
= BinaryPartAbstractImage.createImagePart(presentationMLPackage, slidePart, file);
Relationship rel = pp.getRelationshipsPart().getRelationshipByID("rId8");
System.out.println("Relationship:::::::s: " +imagePart.getSourceRelationship().getId());
// pp.removeSlide(rel);
java.util.HashMap<String, String>mappings = new java.util.HashMap<String, String>();
mappings.put("rId8", imagePart.getSourceRelationship().getId());
String outputfilepath = "C:\\Work\\24Jan2018_CheckOut\\PPT-TRAILS\\Success.pptx";
//presentationMLPackage.save(new java.io.File(outputfilepath));
SaveToZipFile saver = new SaveToZipFile(presentationMLPackage);
saver.save(outputfilepath);
System.out.println("\n\n done .. saved " + outputfilepath);
}
Please help me how to replace an image in the generated PPT.

Saranya

I am having trouble with parsing some html files from a directory into an output directory. I'm using Jsoup to remove HTML tags and writing to an output directory but some of the data is lost when I'm testing it. What I want to do in the end with the parsed files is to populate a hashmap so that I can sort the words by frequency and then in a separate directory sort them by alphabetical order. This compiles and runs, but I am getting stuck at the very end when it comes to write out. Code would be lovely and all, but I'm only interested in the steps to take in order to set this entire thing up. Thank you.
