I was just looking to see if anyone knows about an open source app using the xml interface. I just started dabbling with the xml interface a little bit and it helps to look at what others are doing. I am looking for a console type app for the operator. Very simple operations like transfer, hold, status, park, etc. We are currently using the FOP, but I always have to update the fop configs to add a new button after creating/changing an extension. Our data is in a realtime DB, so I guess I could build a console that uses the realtime db and the xml interface. Anyone else in the same boat? Thanks.
