Let’s clarify a few concepts as part working with wis2box:

  • topic hierarchy: structure defined by WMO to categorize and classify data, allowing for easy and efficient search and identification

  • discovery metadata: description of a dataset to be included in the WIS 2.0 Global Discovery Catalogue

  • catalogue: a collection of discovery metadata records

  • station metadata: description of the properties of an observing station, which provides observations and measurements

  • data mappings: the wis2box mechanism to define and associate a topic hierarchy to a processing pipeline
