CETIS makes online documentation system for QTI ASI available
CETIS Assessment SIG member Niall Barr of Strathclyde University has developed a rather nifty system to browse the many elements of QTI as well as a list of possible response types. Not just that, you can discuss them as well.
The resource is mainly of interest to the increasing amounts of IMS QTI developers, but is intended to benefit the development of the spec itself as well.
Niall's guide does this by providing a convenient way of looking up the various QTI 1.2 elements, and see what they are supposed to do according to the IMS Best Practices guideline. The same goes for the response types that the spec provides.
To further enhance best practice, each element and response type has a discussion area were a common interpretation of the element or response type can be reached. The more people participate, therefore, the better the interoperability between different implementations will become.
Lastly, the process of reaching a consensus could very well uncover issues with the current version of QTI that can be addressed in the next version.
You need to register to make use of the discussion facilities, but the online QTI documentation resource can be browsed without it.
