The evolution of Mooshabaya

Mooshabaya is a Mashup generator for XBaya workflow composer of Indiana University. Mooshabaya is implemented by a team of four, and Mentored by Dr. Srinath Perera and Dr.Sanjiva Weerawarana of WSO2 Inc. As the team members we have had several online chats and informal meetings with our mentors. This post will mention only the formal meetings we had regarding the project.

May 22nd [WSO2/Dr.Srinath/All members]: Initiating The Idea : [10 a.m - 11 a.m]
The team meets Dr.Srinath Perera offline. This was the first meeting we had with Dr.Srinath, regarding the project. The project idea was first developed to form to considerable level. Dr.Sanjiva Weerawarana was also present in the meeting.

We decided to implement a mashup generator for the XBaya workflow composer. Currently the workflows are exported as jython scripts or BPEL. Our project will export them as mashups, combining the mashup and workflow domains, including a considerable amount of research, hence this project has not been implemented before. The services will be found from WSO2 Registry and the generated mashups will be deployed into WSO2 Mashup server. It was mentioned that the current implementation of XBaya uses several other components from the Extreme! Labs of Indiana University, including XRegistry.

June 4th [WSO2/Dr.Sanjiva/Dr.Srinath/All members]: Combining the groups : [10 a.m - 12 p.m]
We, with the other group of 4 WSO2 interns, decided to have a merge between the groups and met Dr.Sanjiva Weerawarana and Dr.Srinath Perera. After discussing several ideas and possibilities, the project was finalized.

The other team will be developing "Scalabale and Hierarchical Tuple Spaces". We discussed a use case where our project will develop scripts which can be deployed in browser. That will become a common scenario for both the teams as the other team will have a use case to have a tuple space that runs in a browser. Hence both the teams will be a loosely coupled combined team [M2SC]. Mora Middleware for Scalable Computing (M2SC), will have two independent components those can be developed without much dependency on each other team's component.

July 17th [WSO2/Dr.Srinath/All members]: Further Discussion regarding the use cases and usability :[11 a.m - 12 p.m]
Since Mooshabaya - our project will be based on XBaya source code, we had to install and run XBaya. For XBaya to be running, we needed WS-Messenger. We have installed both WS-Messenger and XBaya. We discussed about XBaya, Messenger, and the other Extreme! Products that are involved in XBaya including XRegistry and XSUL. Discussed further about the requirements. Some basic design constraints were discussed.

July 22nd [CSE/Dr.Srinath/All members]: Discussion on XBaya and Extreme! Labs products : [9 a.m - 9.30 a.m]
We discussed the issues we faced in monitoring workflows using XBaya. After the meeting and discussion XBaya is successfully installed and configured to monitor the workflows.
