It should be possible to identify the extent to which each supports the recommended interoperability points. It should also be possible to determine the level of support for each of the generic scenarios, providing a structured comparison method for digital information systems. A limited set of functionality should be covered in the initial version of the document with aditional functionality being added later in the study. In their simplest form, scenarios are enumerated lists describing the steps required to perform a particular task. User is prompted for search terms.
System presents results to user.
Repeat step 3 until user exits search. The generic scenarios developed in Task 2 and the architecture developed in Task 1 should be used as a basis for gathering high-level requirements from organisations with a requirement to offer a hybrid information environment. Depending on the organisation the requirements may describe a fully or partially existing system or a system that is currently being considered. Interoperability requirements for each of the interoperability point identified in Task 1 should also be considered. The focus should be on functionality rather than specific protocols.
