Wiki source code of Use Cases

Rohan Sobha 28.1 1 Here we present our use cases that we envision for WAF (our prototype). There are six use cases in total of which four were actually implemented in the prototype and the remaining two were thought of, but not taken into account for the current version of WAF. To note: requirements, claims or IDP columns that are filled in with a **-** (hyphen) are there to indicate that there is no requirement, claim or interaction design pattern (IDP) belonging to that specific Use Case (UC) step.
