What is the role of an information consumer in the IoT ecosystem?
a) To collect data from their own sensor deployments and make it
available to others
b) To build a new application that draws on multiple disparate
sources of data, identify relevant data, obtain permission to use it,
and integrate it into their own development
c) To manage access control for IoT platforms
d) To perform a specialist function in the system
B
What does DCAT stand for, and what is its purpose?
a) Data Catalog Vocabulary, a W3C recommendation aimed at
facilitating interoperability between data catalogues
b) Data Control and Access Technology, a system for managing
access control for IoT platforms
c) Data Catalog Visualizer, a tool for representing and exposing IoT
platform catalogues over Web technologies
d) Data Compression and Transformation, a method for reducing
technical barriers faced by both providers and consumers of
information

In the context of IoT, what is the purpose of discovery?
a) To identify which aggregators contain information of interest and
find specific data sets
b) To control access to data provided by information providers
c) To enable data communication between IoT devices and
platforms
