Generally about Actions

In order to add certain ‘Actions’ to items, several ways are available:

  • in case the item is located on one of the large or medium-sized german research vessels (Polarstern, Sonne, Meteor, Maria S. Merian, Alkor, Heincke, and Poseidon) you could use the autocompletion functionality (strongly recommended). Simply type the first three characters of the station label as listed in PANGAEA’s expedition catalogue ( to comfortably get the metadata fields under ‘Action’ filled out for you and this way avoiding possible typos,
  • if the autocomplete feature does not apply to your items you could use user interface to insert the mandatory information, or
  • you could use the Rest-API ( to insert the information by any programming language that is capable to sent HTTP requests.

The actions

  • calibration
  • comissioned
  • deployment
  • mount

automatically create a new version of the item (including a handle, such as this one: to have

Since creating a new version can be omitted when reassigning an item, there is still the chance to do so (just for the case you recognized it was mistakenly without version) by manually create the mounting event and hence triggering the creation of a version. 

‘Actions’ additionally give you as a user a chance to become more visible in DWS. Properly added missions make this data stream pop up there in the facet ‘Mission’. Furthermore entries of the types ‘Mission’ and ‘Deployment’ are searchable in DWS.

Field in DWS to filter for Action Labels from

If the above mentioned facts were not convincing you to manage your metadata, the standardized entries from can be forwarded to other places with ease, e.g. applications that make use of the API, such as Jupyter/R notebooks, knitr, webpages, portals or something alike.

Creating Actions

Adding new Actions in

When adding new events some fields are mandatory and some are not. Nonetheless it is strongly recommended to fill in every field, since several services, such as autoQC ( make use of it. Furthermore, especially the spatial information can be used in map applications.

Calibration15The item was recalibrated, the respective Calibration certificates and/or associated documents should be supplied via the Resources tab in the upper navigation banner.c922c7f9-a2d8-464c-8f30-3ae60a30394a
Commissioned215This Event Type applies to large-scale platforms, such as land-based stations, research vessels, and aircrafts. It describes the beginning of the operational use of this device.3a791fbc-f2c8-4277-91e7-2c68e8c7dc55
Configuration317Describes a change in an items configuration (something new has been mounted, the item has been recalibrated …)9fc7575c-6125-4dc6-89a7-eee2eb25755b
Decommissioned216This Event Type applies to large-scale platforms, such as land-based stations, research vessels, and aircrafts. It describes the end of the operational use of this device.94ae38e6-8fda-4c07-b40c-01833982812f
Deployment187A device is deployed, means it is in operational use. Deployment applies to small-scale vehicles and ship-operated devices, such as CTD rosettes, buoys, etc..047a4f46-020b-4187-808a-6f245caebbc3
Information50Describes issues associated with this item relevant for its operation. Includes failure and maintenance information.d865bf37-04c3-44f5-a474-0458dc68f915
Maintenance16The Event Type Maintenance describes functional checks, servicing, repairing or replacing of parts. The device might still be operational, but the device's measurements might be affected by means of maintenance.d1a2a98a-8ad1-44a5-902f-9ce1513262cf
Mission182A Mission refers to the device's operation within a defined range of time and purpose.78318577-0e23-4dfe-ad2b-bfe6cb23b9a7
Mount25The device installed/attached to a parental device. The Event Type Mount mostly applies to ship- and airborne sensors.13c8e2d6-a0ff-4612-bc7c-3d6540f52655
Partial_failure200The Event Type Partial Failure should be set if the device's functionality somehow is restricted or limited.f663f3a3-78bc-4c47-a9eb-f146571907e8
Processing470Used in laboratory context, when samples run down a processing chain.e45c70dc-5b6d-4ab9-a3eb-9d2c1597dad2
Recovery188When a device is retrieved from water or ice the Event Type Recovery should be set. Then it is no longer operational. This usually applies to buoys or moorings.6fac6351-0c4a-48c1-87e4-a5e721f9c1ae
Total_failure201The Event Type Total Failure denominates the total loss of functionality of the respective device. Any re-use is foreclosed.a6f292be-e5f6-4f4f-b34a-8e335675ed92
Unmount26The device is extracted from a parental device. The Event Type Unmount mostly applies to ship- and airborne sensors.6f705b42-bc1f-4f47-89c8-7d89efabfdd5
