OpenDataKit =========== Overview -------- OpenDataKit is a suite of tools that help organizations collect and manage data, typically via mobile application. The most interesting components used on SpotterVM are - **ODK Aggregate** - Main data storage server and analysis tool, written in Java, running on Apache Tomcat using PostgreSQL database. - **ODK Build** - Drag-and-drop form designer, written in Ruby 2.4, requires NodeJS for frontend assets. - **build2xlsform** - Service to convert ODK Build forms to xlsform-compliant XLSX, written in LiveScript (NodeJS). Upstream URLs: - **ODK Aggregate** - https://github.com/getodk/build - **ODK Build** - https://github.com/getodk/build - **build2xlsform** - https://github.com/getodk/build2xlsform ODK Build exports ----------------- ODK Build runs in a container separate from ODK Aggregate and doesn't use any database engine for its persistent storage. ODK Build can however export the designed form to ODK Aggregate via HTTP endpoint. In case HTTPS is used with self-signed certificate, it needs to be imported to OpenSSL trust store prior to first communication attempt. In our container, this is ensured by ``add-ca-cert`` script. build2xlsform lives in the same container as ODK Build and allows for export of ODK Build JSON forms to XLSX files editable via any modern office suite.
