Motivation

From deciding whether to carry an umbrella in the morning to helping an airplane pilot choose the best flight path, accurate and timely weather information is essential to keeping us comfortable and safe.

The LEAD project from University of Indiana provides a Web-based virtual organization and portal to scientific research tools for meteorologists, atmospheric scientists, and anyone who wants to interactively explore the weather as it evolves.

A Whether Forecasting Process…

The Story

So a scientist requires a system ... • To depict the real world problems or scientific scenarios as workflows.

• To execute the workflows and monitor them in real time.

• To secure some of his workflows from unauthorized access, while accessing the secured services.

5

Story Continues ...

• Traditional workflow languages or xml technologies have a large learning curve.

• He wants to prototype the workflows quickly.

• He is interested in using the data provided by web based APIs.

• He likes to integrate data sources like web feeds into the system.

6

Mashups to the rescue

• Mashups aggregate contents and services from two or more sources.

• Rapidly developed by mashing up APIs.

• Little investment in learning the mashup APIs and for using them.

7

Mooshabaya

• Exploring synergy of the workflow domain and the mashup domain by a potential merge.

8

Not Re-inventing the Wheel..

• XBaya Graphical Workflow Composer from Indiana University as the workflow composer of Mooshabaya.

• WSO2 Mashup Server to deploy the generated mashups.

• WSO2 Registry for the services.

Discussion

Using mashups to deploy workflows as a light-weight medium

Rapid workflow prototyping and testing Complete life cycle of a mashup Seamless data aggregation to workflows

taking service-level requirements in-to consideration

23

Conclusion and Future work

Using Mooshabaya as base... Mashup perspective Workflow perspective

Providing non-functional requirements Security Monitoring RM Atomic processes etc.

24

Conclusion and Future work

Let's not converting high value business processes into mashups

Rather use mashups based implementations in data intensive workflows with the consideration of security, monitoring etc.
