The migration tool extracts the metadata and inserts it into a management tool for sensor and device data using API calls. The tool is implemented in Python and highly configurable in terms of the source database and the target sensor-management system. We use it to migrate the Tereno metadata to the Helmholtz Sensor Management System. Loup, Ulrich(Forschungszentrum Jülich)
