Motivation for a WoT Thing Description (TD)
Who are you?
What kind of function do you have?
What kind of data do you serve?
How can I access the data/function?
Atomic use cases: engineering, application/service development, discovery / identification, plug & play (e.g., T2T), monitoring, …
What kind of protocols/encodings do you support?
Are there some security constrains?

TD Overview
6
Goals: - minimal vocabulary set to describes Things capabilities and how to access/use these
- extensible to add domain specific and unspecific context
- optimized representation for being feasible to resource constrained Things
Current Working Assumption JSON-LD Sample

Collaboration of W3C WoT and BIG IoT
- Evolve W3C WoT’s thing description to platform descriptionenables “understanding” of what a IoT platform can serve us concepts will rely on the W3C WoT TD and scale it up to the platform level
- Important for Thing-2-Thing (T2T) interaction demos/scenarios in BIG IoTExamples:
- Things from city infrastructure (e.g., traffic lights) and vehicles- danger detection (e.g., bicycle vs. vehicle)- …
- Based on our experiences we can give input to the W3C WoT group and vice versa
