The Nigeria e-Government Interoperability Framework (Ne-GIF) provides a structured approach for integrating government ICT systems to deliver seamless, citizen-centric public services. It details levels of interoperability organisational, semantic, and technical and prescribes standards for data exchange, open metadata, and common interfaces. This framework promotes “Whole-of-Government” coordination, emphasising collaboration, resource sharing, and consistent technical guidelines, all of which streamline service delivery, reduce duplication, and facilitate efficient e-government operations in Nigeria.
