1.go.owl源码

<owl:Class rdf:about="http://purl.obolibrary.org/obo/GO_0045019">
    <obo:IAO_0000115 rdf:datatype="http://www.w3.org/2001/XMLSchema#string">Any process that stops, prevents, or reduces the frequency, rate or extent of the chemical reactions 
and pathways resulting in the formation of nitric oxide.</obo:IAO_0000115>
    <oboInOwl:id rdf:datatype="http://www.w3.org/2001/XMLSchema#string">GO:0045019</oboInOwl:id>

    <oboInOwl:hasExactSynonym rdf:datatype="http://www.w3.org/2001/XMLSchema#string">down regulation of nitric oxide biosynthetic process</oboInOwl:hasExactSynonym>
    <oboInOwl:hasExactSynonym rdf:datatype="http://www.w3.org/2001/XMLSchema#string">down-regulation of nitric oxide biosynthetic process</oboInOwl:hasExactSynonym>

    <oboInOwl:hasExactSynonym rdf:datatype="http://www.w3.org/2001/XMLSchema#string">negative regulation of nitric oxide synthesis</oboInOwl:hasExactSynonym>
</owl:Class>

2.实现程序

package test;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;

import org.apache.jena.ontology.AnnotationProperty;

import org.apache.jena.ontology.OntClass;
import org.apache.jena.ontology.OntModel;
import org.apache.jena.ontology.OntModelSpec;

import org.apache.jena.rdf.model.ModelFactory;
import org.apache.jena.rdf.model.Property;

public class Insert2 {

    public static void main(String args[]) throws FileNotFoundException{
        final OntModel ontModel = ModelFactory.createOntologyModel(OntModelSpec.OWL_MEM);
        ontModel.read(new FileInputStream("f://myowl.owl"), "");

        String OBO = "http://purl.obolibrary.org/obo/";
        String OBOINOWL = "http://www.geneontology.org/formats/oboInOwl#";
        //新建类
        OntClass ontClass = ontModel.createClass(OBO+"GO_0045019");

        //新建property
        AnnotationProperty p = ontModel.createAnnotationProperty(OBO+"IAO_0000115");
        p.addLabel("definition", "");

        Property p1 = ontModel.createProperty(OBOINOWL+"id");
        Property p2 = ontModel.createProperty(OBOINOWL+"hasOBONamespace");
        Property p3 = ontModel.createProperty(OBOINOWL+"hasExactSynonym");

        ontClass.addProperty(p, "Any process that stops, prevents, or reduces the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of nitric oxide.");
        ontClass.addProperty(p1, "GO:0045019");
        ontClass.addProperty(p2, "biological_process");
        ontClass.addProperty(p3, "down regulation of nitric oxide biosynthetic process");

        ontModel.write(new FileOutputStream("f://go-minus1.owl"));
    }

}

3.实现结果

 <owl:Class rdf:about="http://purl.obolibrary.org/obo/GO_0045019">
    <oboInOwl:hasExactSynonym>down regulation of nitric oxide biosynthetic process</oboInOwl:hasExactSynonym>
    <oboInOwl:hasOBONamespace>biological_process</oboInOwl:hasOBONamespace>
    <oboInOwl:id>GO:0045019</oboInOwl:id>
    <obo:IAO_0000115>Any process that stops, prevents, or reduces the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of nitric oxide.</obo:IAO_0000115>
  </owl:Class>

  <owl:AnnotationProperty rdf:about="http://purl.obolibrary.org/obo/IAO_0000115">
    <rdfs:label>definition</rdfs:label>
  </owl:AnnotationProperty>
