Dear FIWARE team,

I am writing to you in order to inform you about my recent article
published in MDPI-Sensors journal. The article elaborates on the use of
FIWARE NGSIv2 data model and API for enabling semantic interoperability
among diverse application domains such as video processing, social media
integration, weather data, etc.

The article is available here:

Abstract: One of the main obstacles towards the promotion of IoT
adoption and innovation is data interoperability. Facilitating
cross-domain interoperability is expected to be the core element for the
realisation of the next generation of the IoT computing paradigm that is
already taking shape under the name of Internet of Everything (IoE). In
this article, an analysis of the current status on IoT semantic
interoperability is presented that leads to the identification of a set
of generic requirements that act as fundamental design principles for
the specification of interoperability enabling solutions. In addition,
an extension of NGSIv2 data model and API (de-facto) standards is
proposed aiming to bridge the gap among IoT and social media and hence
to integrate user communities with cyber-physical systems. These
specifications have been utilised for the implementation of the IoT2Edge
interoperability enabling mechanism which is evaluated within the
context of a catastrophic wildfire incident that took place in Greece on
July 2018. Weather data, social media activity, video recordings from
the fire, sensor measurements and satellite data, linked to the location
and the time of this fire incident have been collected, modeled in a
uniform manner and fed to an early fire detection decision support
system. The findings of the experiment certify that achieving minimum
data interoperability with light-weight, plug-n-play mechanisms can be
realised with significant benefits for our society.

Best Regards,
Nikos Kalatzis
