BlueSquare is migrating openIMIS to the new modular architecture and plans to have a fully open sourced software stack for openIMIS by October 2022 ( Project: 2020.T3 Modularisation ). A few things from the legacy version will not be included and need to be done in other engagements.
The RESTful API is currently used by the mobile applications in Nepal an Tanzania. It will have to be migrated to PYTHON based on a GraphQL layer, that will be provided by Bluesquare.
