Prototyping Fedora widgets framework

Hi all, As discussed over IRC, I am working on prototyping a framework to power generic widgets for Fedora. This framework will allow writing widgets for Fedora in Python, mostly. Basic components ============== Dispatcher ---------------- Dispatcher is part of a daemon process which keeps on listening to fedmsg messages and invoking widgets to save data as needed. Widgets can be tied to the dispatcher using signals, observer patterns, etc. Widget ---------- I define a widget implementation as a standalone entity which knows: 1. How to handle raw fedmsg data, format it and save it for enabling faster query 2. Render data from saved data. API ------ Provide REST interface to fetch data from a widget for a particular entity, say, badges info for a user for UserBadgesWidget. I have started working on a prototype based on the Observer design pattern here[1]. Please provide your feedback on the same. I am also thinking to work on a prototype based on signals, to see which prototype allows us to expose friendly interfaces for writing widgets.
