This is a web application to gather how subjects feel about a variety of objects. It is primarily used as a custom replacement of Doodle or FramaDate with more preference levels and a transposed presentation (so that when there are a lot of time slots and a few people, one scrolls vertically instead of horizontally).
It consists of a CHICKEN Scheme HTTP server which handles POST requests and updates a JSON representation of the data, and some static files served by a regular webserver (e.g. nginx).
It depends on Spiffy webserver and sql-de-lite binding of SQLite for persistent storage.
