WoT scripting API use cases

The following document describes some possible scenarios of the interactions between WoT Scripts and the underlying runtime. In particular, it focuses on how scripts will use interaction affordances to communicate with a remote Consumed Thing.

The use cases are divided into three categories: high, middle, and low-level interactions. The different levels express a different level of control about data transmission/acquisition/translation. At the lowest level the application has the complete control of the data packets transmitted/acquired over the network, wheres at the highest level most of these details are hidden by the implementation.

note: Currently, security use cases are ignored

High level interactions [DRAFT]

In this use case the application does not have any particular requirements about how the data is retrieved or transmitted. Therefore, it seeks the easiest way to obtain/communicate the desired information. Those scenarios can be further dived in to two

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

Follow standard conventions.
Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
Boy scout rule. Leave the campground cleaner than you found it.
Always find root cause. Always look for the root cause of a problem.
