List of attributes

DMQS metadata

In the R&D project Datenmanagement und Qualitätssicherung im Verkehrswasserbau (DMQS) new guidelines for the creation of metadata were formulated, especially in connexion with use of simulation programs (see Mathematical Models for Coastal Areas and Estuaries).

All resulting recommendations are described in recording of metadata for a simulation (available in German only). Recommendations for the creation of metadata can be regarded as a replacement for file input from nc_meta.dat (see subsequent section). They shall be used with priority.

Metadata from nc_meta.dat or other input steering data files

Creation of metadata shall be carried through with priority according to the recommendations given in the above section related to DMQS metadata. If this is not applicable, input from nc_meta.dat can be regarded as an alternative.

Remarks

Global attributes describe the data source as well as the institution which originally created the data. An overview of the use history is also given. Also informations about metadata conventions used are contained.
From the attributes listed above not all of them are always present.
