The metadata flow of MOSAiC is based on the O2A framework:

General Data Flow

Data annotated with metadata regarding device description and device operation will be stored in the onboard MOSAiC Central Storage (MCS) and transferred to the AWI storage (land MCS) after each leg. The land MCS will be accessible only to MOSAiC Consortium members prior to the data public release date 1.1.2023.

Data flow onboard Polarstern in MOSAiC

From left to right: Metadata of every instrument is registered in SENSOR. Data acquisition is logged with DSHIP Actionlog. Data is ingested into the MOSAiC Central Storage (MCS). Ingested data can be monitored with different tools providing that it is converted accordingly and registered appropriately with the monitoring tools. Data analysis onboard is supported with virtual workspaces. Eventually all data shall be published in an appropriate data repository, e.g. PANGAEA.

...

The directory structure on the MCS is derived from the URN of the device entered SENSOR. Each respective device or subdevice folder will contain a subdirectory named according to the device operation ID in DShip in which the device was used. Raw data obtained during each device operation have to be uploaded (automatically or manually by Data PI) to the respective subdirectory.
