Using googles panorama API

I want to use google's API for displaying panoramas. Apparently I need for input a jpg with the panorama, in which I embed the metadata in XMP format. How can this be done? is it my job as a developer or the one's who creates the panorama? can this be done with a tool? ie photoshop?

Ok this is how I did it, I used photoshop which has an option to pass metadata from a custom template so I created an XMP file using the metadata mentioned in google documentation page. Hope it helps anyone who finds this post!
