Searchable metadata

Advanced search based on field name metadata

Advanced search based on field names and further metadata

Simple search through metadata content

  1. Fields annotated with an asterisk were clearly obligatory. For Zenodo, options for the advanced search can be found in the search guide (https://help.zenodo.org/guides/search/). For Pangaea, the metadata required for submission (https://wiki.pangaea.de/wiki/Data_submission), the reference height (https://wiki.pangaea.de/wiki/Geocode), and the advanced search options (https://wiki.pangaea.de/wiki/Pangaea_search) can be found in the Pangaea wiki. For AADC, we added further metadata not mentioned in the submission mask based on metadata from existing data sets. It was not clear to us which further metadata is obligatory for AADC in the DIF format metadata record.
