CommonHIT is a simple, small library for reducing the boilerplate usually needed when designing HITs for Amazon Mechanical Turk.
Status: Experimental.
A small basic example can be found here. The use of foreach templates is described on this page. Be sure to inspect the source code.
The use of heat-map timelines is described on this example page. Again, be sure to inspect the source code of the page.
The example on this page shows how you can reuse a single LLL.Player in a task and distinguish easily between the two uses through the newSession() method.
A full example on how you can use CommonHIT to create an annotation HIT can be found here.
