According to the FDSN stationXML schema, the metadata is organized in 5 levels, imbricated one in another as russian dolls :- the inventory is the higher level of information, which contains all sublevels,
- the network level lists the seismic arrays available in the inventory; it also contains the references and dois needed to acknowledge each dataset,
- the station level gives information about the stations present in an array, including their name and geographical coordinates,
- the channel level gives information about the instrumentation used and the time-period of the measurements,
- the instrument response allows to convert the numerical data into a geophysical signal, such as a displacement, a velocity or an acceleration.
