The “OpenAgri Gatekeeper” serves as an API Gateway with centralised authentication, ensuring secure, efficient, and seamless centralised data exchange between the services in the OpenAgri ecosystem and third-party services. The Gatekeeper responses uses JSON-LD with the OpenAgri Semantic Model to ensure compatibility with modularised and evolving solutions for the agrifood sector, and is deployable on both Edge or Cloud to enable the data sharing through harmonised access to webservices in areas with limited connectivity. It reuses open standards and tools that avoid vendor lock-in, and therefore ensures that the stakeholders maintain full autonomy over their data sharing process.
