Port RDFReactor project to .Net (written in C#)

[About NRDFReactor]:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

NRDFReactor views the RDF data model through object-oriented .NET/C# proxies and makes RDF easy for C# developers. It is somewhat of RDFReactor(in Java) in .NET/C#. However, It not only implements functions of RDFReactor, it adds some features based on RDFReactor.

[Features]::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

• Think in objects, not statements  (RDFReactor)
• Dynamic state (RDFReactor)
• C# interfaces are generated automatically from an RDF    Schema/OWL  (RDFReactor)
• Context class and related operations.
  • contexts often are used for managing data aggregation and recording provenance like in Redland, Jena etc.

Steps of jenerating C# classes:

   1.  Write or find an RDF Schema
   2.  Generate API

      CodeGenerator.generate("schema.rdf", "./src", "nrdfreactor.example","rdfs", true, true);

Example Generated APIs:

public class WfMSContext : NRDFReactorBase {
        public WfMSContext(Model model, System.Uri uri)
            : base(model, WfMSCONTEXT, uri){}
        public void AddActivityID(string actID) {
            Add(ACTIVITYID, actID);
        }
        public void AddCurUser(Person p) {
            Add(CURUSER, p);
        }
        public void AddPara1(string para) {
            Add(PARA1, para);
        }
        ?­?­
}

public class Person : NRDFReactorBase {
    public void AddPhone(int value) {
            Add(FOAFPHONE, value);
        }
        public void AddPhone(int value, Context cxt) {
            Add(FOAFPHONE, value, cxt);
        }
        public int GetPhone(){
            return (int)Get(FOAFPHONE);
        }
        public int GetPhone(Context cxt){
            return (int)Get(FOAFPHONE);
        }
        ?­?­
}

3. using NRDFReactor:

Model model = RDFTKWrapper.CreateDefaultModel();
WfMSContext  wfmscxt = new WfMSContext(m,"http://zz.com/#WfMSContext");
Person p1 = new Person(m, "http://xx.com/#person1",wfmscxt);
Person p2 = new Person(m, "http://yy.com/#person2",wfmscxt);

p1.setNameInCxt("Joe");
p2.setNameInCxt("Jim");
p1.addKnowsInCxt(p2);
               
Person[] p1friends = p1.getAllKnowsInCxt();
for (int i = 0; i < p1friends.length; i++) {
  System.out.println(p1.getNameInCxt()+" knows "+p1friends[i].getNameInCxt() );
}
