Flag Conversions

FlagConversions are defined to map internal quality flags to external quality flags. For each flag to be converted a conversion can be identified, but a default flag may also be given to ensure the exported or imported data carries a flag. A flag to identify missing values must also be configured. Until version 2008.01, each FlagConversion file had to be registered in the FlagConversionsDescriptors configuration (see Regional Configuration), but this descriptor file has been obsolete since version 2008.01 and since version 2016.01 this file is no longer supported. The Id used in registering the FlagConversion is the same as the name of the configuration file. When available on the file system, the name of the XML file for configuring a FlagConversions called for example NWPFlags may be:

NWPFlags 1.00 default.xml

NWPFlags

Fixed file name for the NWPFlags FlagConversions.

1.00

Version number

default

Unit to indicate the version is the default configuration (otherwise omitted).
