Miss Grant's Controller 2012-03-09 (mca) Sample hypermedia M2M app based on Martin Fowler's Miss Grant's Controller example found in his book "Domain Specific Languages". This example appears in the first chapter. ASSUMED GOAL The goal for this project is to open the "secret" panel. It is only possible after certain tasks are completed (i.e. certain items are in the proper "state"). HUMAN Version (app.js) The version "tuned" for humans to use provides more than two transition options in responses. Humans are given the options to "play around" with the set of objects in order to reach the proper "state" and achieve success. To run this version, use app.js as the startup script and follow along in the UI. MACHINE Version (m2m-app.js) The version "tuned" for machines to use supports the same outcome, but does so via a different "interface" to the same set of states. The machine is only offered up to two transition options each time (and one of them is to return to the start). The machine also is not asked to provide any unique variables for the transitions; just to use the data supplied in the affordance. With these constraints the machine interface is able to reach teh same goal in almost the same number of transitions. To run this version, usem2m-app.js as the startup script and follow along in the UI. Note that the MACHINE version offers a "start bot" option. This will run a bot that follows the action elements to achieve the goal. BTW - since the interface for the bot version is kept very limited (only one option moves the application forward), it is possible to introduce new steps along the chain and the bot will still achieve the goal (w/o any change in the user-agent programming). http://my.safaribooksonline.com/book/software-engineering-and-development/ide/9780132107549
