Open Knowledge Nepal (OKN) is a member of the Data for Development (D4D) programme which is coordinated by The Asia Foundation. As a part of D4D, OKN launched the ‘Data Unit Strengthening Program’ in Tulsipur Sub-Metropolitan City with the aim of strengthening municipal data management. Through this programme OKN identified significant gaps in: A. The connectivity and interoperability between the different management information systems (MISs) in use B. Public access to municipal data. In response to these gaps, OKN developed a concept for an Integrated Data Management System (IDMS) to be implemented by each municipality. An IDMS is an integrated database with a publicly accessible interactive dashboard that has capabilities for semi-automated and automated data retrieval, the latter via APIs. It facilitates improved data sharing, storage and accessibility.
