Metadata

Metadata is information about data. It usually contains information such as who, what, when, where and how were data produced. The mandatory metadata in Pangaea are Event label, with its geographical position and the PI of the data, even though in most cases, this will not be sufficient to fully understand a data set. Any information available should be provided.

Pangaea should not be used for the management of comprehensive metadata only, e.g. as reference database or just listing campaigns/events of a project. In principle metadata are archived only, if the related data are available and archived in the relational system or the storage archive of Pangaea.

Metadata fields consist of those defining a sampling locality (event) and fields desribing the factual data for each data set (bold are mandatory fields). The size/composition of a data set depends on the definition of its granularity.
