i4Trust contributes to break "data silos" and stimulate sharing, re-using and trading of data assets by launching an "incubator of Trusted B2B Data Sharing ecosystems of collaborating SMEs linked to Digital Innovation Hubs". Actors in these ecosystems will share data by using iSHARE, CEF and FIWARE building blocks. Goal is boosting the participation of SMEs in development of innovative services in different sectors based on sharing of data across value chains. i4Trust value proposition will contribute to build trust with data users and data suppliers by supporting 32 Bottom Up Experiments that will involve at least 150 SMEs and 32 Digital Innovation Hubs. The project will help them in understanding the demand for data, establishing data sharing partnerships, identifying concrete use cases relying on trusted sharing of data, by adopting user-friendly and proved technologies for B2B data sharing such as iSHARE, FIWARE, and CEF Building Blocks, which cover all the operational, legal, technical and governance aspects related with B2B Data Sharing. The project execution relies on a LEAN consortium of experts in B2B Data Sharing with deep roots in the European DIH Network. The project coordinator, FIWARE Foundation, is linked to a network of European FIWARE iHubs and they also bring a deep expertise in FIWARE and CEF Building Blocks technologies. FundingBox Accelerator – European leader in Financial Support to Third Parties – is also a member of 6 DIHs and partner of another 37 all across Europe. The iSHARE Foundation, on the other hand, brings to the project a deep knowledge in operational, technical, legal and governance issues related to B2B Data Sharing they have accumulated during the research and development process related with the launch of iSHARE, a neutral trusted data sharing network, with high international acknowledgement and uptake.
