This publication showcases the goals of the FIESTA-IoT project. The presented testbed was designed to facilitate interoperability between disjointed Internet of Things (IoT) environments using a common semantic approach. Published in April 2018, the areas explored in this work remain highly timely and important today; the platform opened for access in May 2018, allowing a range of institutions to interconnect their IoT facilities. In light of this progress, however, this two-page paper provides little detail on how the platform’s features have been enabled.

FIESTA-IoT is described as enabling experimentation as a service (EaaS) and facilitating service orchestration; however, brief details are not included on how this is achieved. These are significant areas of ongoing research within the IoT, and are ones which are not easily solved due to the ad hoc and siloed way in which IoT technologies are typically deployed. As a result, the reader is left with questions: How is interoperability facilitated to support dataset sharing? How does the middleware enable testbed-agnostic operation? How do the semantic definitions integrate the siloed systems? These important details can help to uncover the market gap that this research responds to.

Unfortunately, few references are provided to elicit this information; deliverables from the project, as cited in the reference list, include the FIESTA-IoT YouTube channel and a book chapter. Additionally, the project leaves a legacy behind at http://fiesta-iot.eu/; however, similar questions also arise here, as “training” links on the site are no longer operational.
