O2A data is archived. The data structure for archiving is described here. The SENSOR's parameter codes (URNs, Uniform Resource Names), e.g. vessel:polarstern:hydrosweep_ds3
describes the root base storage directory for this specific device. This base directory is defined by the metadata description in sensor.awi.de. Examples for base directory: vessel:polarstern:hydrosweep_ds3 , towed_systems:loki_10001_02
...
Examples for different level of nesting in Sensor URNs:
(type:item:item:item) vessel:polarstern:tsk1:sbe38
...
(type:item) towed_systems:loki_10001_02

Sensor URNs describe the data storage location in our archive. E.g. temperature data from the sbe38 sensor, from termosalinograph keel 1 tsk1, on vessel polarstern, are stored unter the root directory /vessel/polarstern/tsk1/sbe38/. Picture data from loki_10001_02 are archived under /towed_systems/loki_10001_02/. This is the base-directory.
The base-directory is given by the sensor urn. Expedition data is located under /base-directory/exdata/ The first level describes the expedition.

Examples for expeditions: PS120, PS122_1, MSM09_3, HE_400, * data/[year/[month/[day]]]/
