Wolfram Alpha is a computational knowledge engine at Wolfram.com. It is a pretty neat application at aggregating content and data and displaying it using powerful graphing, statistical techniques and mathematical forms. It also has a method of displaying musical notes, chords, progressions, etc.
I noticed that it also displays Hindustani ragas:

However it doesn't yet display Carnatic ragas. I guess it displays ragas like Hamsadhwani because they are shared between Carnatic and Hindustani (for the same scale).
Any suggestions, ideas, inputs?
