What is the expected type of semantic web applications?

a tool or service that assists users in manipulating semantically enriched resources based on shared ontology.

Manipulation includes:

• Model - determine resource models by selecting shared ontology
• Edit - change
• Import/Export - Format interpobability
• Publish - obtain annotated and semantically enriched resources
• Reuse - Reasoning, search, representation and visualisation

Key features includes:

• Distributed - the semantic data should be ideally located in different places
• Inteprobable - if it is a web service, it must follow WS-I.

Key issues includes:

• Storage
• Modular and reusable resource processing - e.g., namespace driven resource consumer auto-loading
• Provenance

MCV - Model, Controller and View

Model: ontology, semantics data such as OWL and RDF triples

Controller: Ruby
http://wiki.rubyonrails.com/rails shows a description of the Rails MCV

make a web service client using axis

java org.apache.axis.wsdl.WSDL2Java SimilarSearch.wsdl

will generate a set of helper classes according to the wsdl definition.

then make a client java as below:

/*

/**

package SimilarSearch;

import java.rmi.RemoteException;

import javax.xml.rpc.ServiceException;

public class similarSearchClientTester {

public static void main(String[] args) {

// create an instance of our service locator
SimilarSearchServiceLocator locator = new SimilarSearchServiceLocator();

// create an instance or our SoapBindingStub
SimilarSearchBindingStub stub=null;
try {
stub = (SimilarSearchBindingStub) locator.getSimilarSearchPort();
} catch (ServiceException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}

SimilarSearchIn in = new SimilarSearchIn();
in.setNumber("ct01003");

// make a call to a method we created in our web service
try {
System.out.println("read to similar search");
SimilarSearchOut out = stub.doSearch(in);
System.out.println("result:"+out.toString());

} catch (RemoteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}
}

useful commands and tips

% java org.apache.axis.client.AdminClient list


deploy a web service:
% java org.apache.axis.client.AdminClient deploy.wsdd
Done processing

display an environment parameter
% echo %classpath%

a new command prompt needs to be reopened each time the "myComputer"->property->"enviroment setting" is changed.

testing a web service from browser:
http://localhost:8080/axis/services/SimilarSearch?method=doSearch&number=ct01001
