"The project results were achieved in 7 different work packages.
WP2 interacted with WP3, WP4, WP5 and WP7 by providing the requirements for the specification of the BIG IoT API, marketplace, realization of use cases, and Open Calls.
WP3 provided the BIG IoT API as well as implementations of compliant platforms to the pilots in WP5.
WP4 was responsible for providing the marketplace that connected the different stakeholders and enables the BIG IoT ecosystem for the pilot regions in WP5.
Inputs from WP2, WP3, WP4 and WP5 were used in WP6 and WP7 for the dissemination and exploitation of achieved results.
The key results of the project are:
# The BIG IoT API and its implementation as a software library addresses the interoperability gap. Naturally, it is impossible to dictate one API for the IoT, since purpose and domain of IoT platforms differ. Instead of defining a single gigantic IoT API that covers all possible IoT platform functionalities, the BIG IoT API defines a generic base structure, which can be instantiated by annotation with terms from a semantic vocabulary. The advantage is that the semantic vocabulary is easier to be developed in a community process, which is essential for building a multi-platform IoT ecosystem. In this way the API is kept slim and easy understandable while being generic and applicable in different domains.
# The BIG IoT Marketplace has shown how the market entry barriers to an IoT ecosystem can be further decreased. Such a marketplace is the corner stone of an IoT ecosystem and enables the advertising, discovery and monetization of IoT resources.
# The BIG IoT pilots (Barcelona, Berlin/Wolfsburg, and Piedmont) and 2 open calls evaluated the developed technologies by integrating several IoT platforms that contributed over 220 publicly accessible IoT resources. Together with multiple service and application implementations, these platforms were BIG IoT-enabled.
A key pillar of the project's exploitation path is the contribution of the marketplace implementation and inconjunction with the BIG IoT API implementation to the Eclipse Bridge.IoT open source project. Based on this major achievement, the partners developed exploitation strategies and business models specific to their organizations.
As key dissemination highlights of the BIG IoT project, we list here 2 overview journal articles. These are 2 exmples out of many further publications and talks that are outcome of the project's work.
