University of Moratuwa on top of the world in GSoC

The University of Moratuwa (UoM), Sri Lanka became the top of the world in Google Summer of Code 2009 with 22 students accepted for the second consecutive year.
Google Summer of Code (GSoC) is a global program in which Google awards stipends to hundreds of students who successfully complete a requested free software / open-source coding project during the summer.
Congratulations for all the UoM GSoCers for raising the UoM flag up once again.
I'm very proud to be among the top Sri Lankan GSoC 2009 winners, together with my colleagues from the Computer Science and Engineering Department from University of Moratuwa.
This is because the Computer Science and Engineering department of University of Moratuwa promotes the students to participate to this competition. Especially the open source software organizations like WSO2 Inc. and Lanka Software Foundation promote and guide students on applying for GSOC. Though there is very few open source software organizations located in Sri Lanka, the contribution they have made with the participation of University of Moratuwa towards this remarkable success is marvelous.
Finally I congratulate all the Sri Lankan students who were accepted and completed their GSoC projects for last 4 years and made this small island, Sri Lanka into a rising star.

The project Mooshabaya (මූෂාභය) - Brings the knowledge from workflow domain to Mashup domain

The idea for the project "Mooshabaya" was emergerged as a final year project, coordinated by the department of Computer Science and Engineering, University of Moratuwa.
The project "Mooshabaya" targets to generate Mashups to describe the composed workflows, by modifying XBaya Workflow Composer.
XBaya addresses the above mentioned issue regarding to the modeling of workflows based on web services. It is a graphical client program for workflow composition and monitoring. It provides an easy-to-use GUI for users to compose workflows from Web Services described in WSDL. It helps the developer to build a graphical representation of the workflow. To facilitate the execution phase of the workflow XBaya also enables the developer to insert the concrete deployment details such as end point URLs present in WSDLs to the workflow model metadata as well. To actually make it executable in real world this workflow model has to be converted in to an executable format which can be deployed within an existing workflow execution engine. BPEL is such executable workflow language which can be run inside a WS-BPEL compliant workflow engine. BPEL has been standardized by OASIS standard body. Currently conversion to BPEL from the XBaya workflow model is present where the converted workflow can be deployed in BPEL engines such Apache ODE.
XBaya currently exports the composed workflows into BPEL and Jython. Though Mooshabaya focuses and uses XBaya as its workflow composer, it can easily be generalized to be compatible to any other workflow composer. Mooshabaya will find the services from a service Registry, which governs SOA deployments, and the composed workflows are deployed into a Mashup Server as mashups.

Let's take a look at on what a mashup is. A mashup is a web application that combines data or functionality from two or more sources to create a new service. It enables fast and easy integration of services and data sources using open API s. This enables the realization of workflows in yet another format and which seems to be very promising due to the proliferation of web services and mashup enabled services on the Internet, a classical example being highly popular Google Maps. Currently there is no mechanism to export XBaya workflow models to mashups which we feel is a significant shortcoming. So we intend to fill this void by extending the XBaya export mechanism to include mashup exports. Also to facilitate monitoring of the workflow during its execution we intend to introduce event notification facility in the generated mashup codes.

How a simple mashup looks like.
Here is a simple mashup that will invoke a partner service "AdderService" and return the result inside "invokeFunctionProcessService" operation.

this.serviceName = "FunctionProcess";this.documentation = "Invoke AdderService" ;
system.include("AdderService.js");

invokeFunctionProcessService.inputTypes={"param0" : "Number", "param1" : "Number"};
invokeFunctionProcessService.outputTypes="Number";

function invokeFunctionProcessService(param0, param1)
{
var adderServiceResponse = AdderService.add(param0, param1);
return adderServiceResponse;
}

So this approach enables to create workflows and business process (like BPEL processes) using in simple javascript.

Things to be figured out - Still, we do not have a clear image on how the mashup domain and the mashup technologies would fit in to the existing workflow domain. So still we are not sure about the actual functional requirements of this project.
We are still in the initial stage of this project. So in future we'll bring you more information in a more official way.

Remarkable performances made by Sri Lanka in GSOC

When I went through the Google Summer of Code statistics for last four years I observed the remarkable performances made by Sri Lankan students. Especially the University of Moratuwa has become the top university for the number of accepted students for GSOC projects over the last four years with a count of 57.
This is because the Computer Science and Engineering department of University of Moratuwa promotes the students to participate to this competition. Especially the open source software organizations like WSO2 Inc. and Lanka Software Foundation promote and guide students on applying for GSOC. Though there are very few open source software organaizations located in Sri Lanka, the contribution they have made with the participation of University of Moratuwa towards this remarkable success is marvelous.
Finally I congratulate all the Sri Lankan students who were accepted in GSOC for last 4 years and made this small island, Sri Lanka into a rising star.
