The Astronomical Collaborative Toolkit
ASCOT is a web based framework which facilitates collaboration between astronomers. Through the use of a customizable dashboard interface, users can easily visualize, manipulate and share large data sets from many different sources, available through Virtual Observatories.
By selecting from a list of gadgets, users can arrange their own toolset to construct a persistent dashboard which keeps track of any changes they make to it. After arranging the dashboard how they wish, users can fork or share it with others. Because all of the changes made are persisted on the server, sharing what is on your screen is as simple as sending someone the url to your dashboard.
