Import of metadata and (OpenDAP) grid references (since 2019.02)
It is possible to import gigabytes of grids in a fraction of a second. To achieve this only references to grid data in NetCDF files, OPeNDAP are imported. The grids are streamed from the OPenDAP service or NetCDF file to the wms service, oc, fss. The central database can be released of big gridded model results by exporting the model results directly to OPeNDAP and import the references back in the same workflow. This works even without any configuration changes in other areas as long the OPenDAP service is reachable. When a netcdf file is created in a workflow an external process is often moving this file to the final opendap location later on. This future file url can be configured (since 2021.01). The data becomes visible in the OC as soon the netcdf file is moved to the final location.
