The global attribute DATA_QUALITY specifies information on quality of the data. This attribute is mandatory for datasets which follow a GEOMS template description, otherwise the use is optional. Currently GEOMS does not regulate the content of DATA_QUALITY, thus the data quality classification is  to be defined by the data provider.
