The event Networks of Government and Smart Cities 2022 - Norte Grande, held in early October by Grupo Convergencia, brought together in Resistencia, capital of the province of Chaco, the three pioneer provinces in the implementation of the Digital Ecosystem of Integrability (EDI, in Spanish). Neuquén, as the most experienced case, and Chaco and Catamarca, as spearheads in the replication of data exchange on X-Road, shared their experience in the cultural, regulatory and technological dimensions and, in particular, the challenges faced by public agencies in their adherence.
